Take Wyoming State Highway 410 South out of Mountain View about 8 miles. Where the highway makes a sharp right turn to the west go straight on to Uinta County Road 283 (gravel) and continue to Forest Service Road 072. Follow the signs past the Stateline Campground and past the China Meadows Campground to the China Meadows trailhead.

Super fun moderate hike. Water is plenty considering the river runs along most of the trail. The forest ranger had us move our campsite about twenty feet. He said every campsite needs to be "70 paces" from the lake. Also, fires need to be 1/4 mile from the lake. Stunning landscape and view as you ascend the trail towards the towering red castle. We saw three moose and a bald eagle.

This hike is amazing. The trail follows a stream the entire way, easy to navigate, and pretty flat until reaching the last 1.5 miles of switch backs. I calculated 23 miles round trip, so 11.5 miles each way. The lake is pretty shallow and my friend got leeches on her feet, so watch out for those if you get in. Camping spaces and water are plentiful. I took the China Meadows trail that starts here Forest Rd 186, Evanston, UT 82930. Happy trails!

Great trip with 11-13 year old scouts. This was our second year in a row coming here. We took three days for this trip. Backpacked to the lower lake of red castle and set up camp. Next day went fishing and played around. Fishing was great in the morning. Caught Brooke trout and Tiger trout both on spinner rods and fly fishing rods. Due to wind fishing was best on the West side of the lake. Didn’t make it up to the upper lake though but heard fish are bigger up there. Hiked 5 miles back and set up camp along the river. Last day fished and hiked back to the trailhead. Mosquitos were bad until you used repellent. Needed to reapply every four hours or so. Stars were amazing! No snow. Bring sunscreen. Nights were decent, not freezing. Afternoons were very warm.

Amazing place. Would be 5/5 but the mosquitos are still in full force as of 6/26/18. Mildly muddy. Still patches of snow around the upper red castle lake but the lake is thawed. Nights still chilly. Actually had a few snow flakes in the morning as we were heading out.

Top ten of my lifetime. Did this trail over two days (I'd recommend at least taking three). I started on a Saturday morning around 8:30AM and was at lower red castle in by lunchtime. I had the trail to myself for nearly the entire length. I saw deer, elk, and moose on the way up. Trail is in great condition, and had so many interesting turns, not at all unpleasant. Plenty of water to be had, so pack light and filter. The trail was never really steep, the switchbacks near the end are well graded and don't require a massive effort. Really exhilarating to hear the Red Castle disintegrating with the snow melt. I've recommended this trail to all of my friends, and will be back soon!

Did this a few days ago. Decent amount of mud but nothing crazy. Mosquitoes were decently bad in the trees. We camped in the open above the lake and it was super windy so mosquitoes weren’t a problem for us. Hiked to the upper lake and crossed one small snowfield but the upper lake was 90% ice. Caught 5 brook trout in the lower lake.

Gorgeous hike! Even spotted a moose on the trail not far from the lake. Expect lots of mud, multiple river crossings and TONS of rocks. The drive into the trailhead can be pretty rough also. There was still some snow on the trail 06/10/18 but wasn’t an issue at all. Trailhead had toilets available, no trash cans.

We did this hike in early June. I was worried it would be too cold but it wasn't too bad. There was A LOT of snow melt which resulted in muddy trails. There were plenty of rocks to step on to try to avoid getting muddy. We backpacked in and stayed the night at the lower lake. Red Castle was absolutely beautiful and worth the long hike. This was my first backpacking experience and it was a good one!

The red castle really is worth all the hype. The trail is pretty level and never steep, but the trail surface was trash from all the horse traffic, and really wore my feet out, so wear good shoes. There were moose along the lake. When we went the last weekend in August, it rained for a little bit but it was fine. There were also about a couple hundred sheep being run late at night from east red castle down the valley so that was... interesting. You’ll also pass lots of cows on your way there and the trail appears to be more popular with horse packers than backpackers. So it was more like the High Uintas Farm than a wilderness... still worth it to camp under the red castle.

We had a great time, hiked the entire trail to the lower lake in one day. Camped the night before at China Meadows. Left at 5 am and returned by 2pm. Didn't hike hard and stopped a plenty. Beautiful lake and Red Castle Mt is awesome!! A MUST-DO!

Just did this as a two night backpack over Labor Day weekend. It was stunning! And there are no more mosquitoes!!! I never had to use bug spray once. It also never rained! It is a long 10 mile hike in, but there's so little elevation gain it feels almost flat. There were a lot of groups camping, but everyone was very friendly and I enjoyed talking to great new people. Spent the second day going up to the upper lake for lunch. We sunned on the rock, dipped our feet in, and even swam for a second. We woke up to five moose in our campsite the second morning! I will never forget this incredible experience.

Stuff to think about on this trip:
Bug spray, sunscreen, waterproof shoes, woods stay pretty damp, hiking in some muddy spots, mushrooms, fishing pole, camera, basic survival kit.

This hike will take from 7-9hrs. in. I would suggest camping before the Upper Red Castle Lake. May be wise to bring rain gear if you don't typically pack it. It's worth the hike just to cleanse the soul.
Just go with it. It's good for you. You'll not have cell service.

Not a very difficult hike. Although you will find that most of the trail is mud as it's a heavily used equestrian trail. Dog friendly. Look for moose in the meadows! Mosquitos are plentiful. Trails seems busy on weekends.. We backpacked in and stayed two nights at Lower Red Castle Lake. Took a day hike to Red Castle Lake as it's only about two miles past Lower Red Castle Lake. Very scenic and peaceful place. Worth every mile!

This trail is the most beautiful trail I've ever hiked. Also the longest and I read some of these reviews saying it's too hard and what not.. well by the time I got to the lower lake I had been up for a total of 26 hours from working and then driving 2.5 hours and then taking the 6 hours it took me to get to the lower lake and although strenuous. It's not at all difficult. It's super muddy and it hailed on us everyday so be prepared. The upper castle lake doesn't provide much to look at but when you're up there looking out over the land and you can see red castle and the lower lake it's worth the hour hike over the boulders to the west of the red castle lake.

I've been making the trek to RedCastle for 27 years... it's never disappointing! I chose 4 stars because of the current condition of the trail... it's muddy and wet up there, lots of damage to navigate from horse packing, if you are on a horse 5 stars.
The fishing was great at the middle lake, nailed the tigers and cuts. Use black and yellow jigs, wooly buggers.
Campers need to be more tidy and clean.. came across a few spots where human waste or trash was noticable... bark beetles have wreaked havoc on about 80 percent of the lower pines.. but up above the switch backs ... the pines are pretty healthy. Such a beautiful place to visit and come back to!

Trail conditions were okay. Tons of horseback riders; makeing the trail really muddy at some points. Lots of mosquitoes. We spent a few days there and camped at a different place each night. Most camps had trash. Fishing was amazing. Day hikes were fun. Sunsets and weather conditions were good. Rained daily for about an hour in the evenings. Would definitely recommend.

Backpacked this in July, 2016. One of my favorite trails in the Uintas! I spent many nights in the Uintas as a boy scout and this was everything I remember and more. Saw a bunch of moose and saw some really deep back woods country only few can imagine if you've been here. Great two night adventure.

Great trail! Amazing views. The afternoon thunderstorms in the Unitas really are a thing so pack appropriately. Lots of bugs as well. Tons of moose in that area so pack your cameras.

One of the most beautiful hikes! This trail is a MUST. Super easy trail along the river into the open meadow and up the Red Castle Lakes.

Don't listen to Clayton(below), we hiked this trail with 3 beginners and not one person had an issue reaching the lake. Everyone carried 35lb packs and had no issues, very few breaks were necessary and the elevation gain was very moderate. Even the switch backs were extremely casual and short lived. The scenery was amazing and we had the entire lake to ourselves! The bugs were in abundance and constant application of bug spray was absolutely necessary but that was to be expected. I recommend this hike for everyone, including first timers.

Additionally I didn't download the map from this app and still tracked the trail with no issues.

9.8 miles, 3.4 hours, 1450 elevation change.

I'm so upset this trail was rated as "easy". So long story, but we ended up hiking in about 7 miles, and my friend decided he couldn't make the journey to the lake, so we backtracked a mile or so, headed up another trail for another mile or so. He sat down and I dropped off my pack, hiked in to see if I could find Lake Hessie about 2 miles, decided he couldn't get there, so I hiked back to where he was, and we put back all our gear and hiked all the way back to the car and headed home.

Now, maybe this wouldn't be too bad with just food and water, but it definitely wasn't easy with a tent and fishing gear. There were no distance markers whatsoever along the trail, so you never had any idea how far you had gone, or how far it was to go. I really think that would have been a huge help.

I'm giving the trail a 3 rating, because I never made it to the lakes, but the trail was pretty. We did see two moose. BEWARE, there are a LOT, I mean a LOT of mosquitos. They absolutely want to eat you, and possibly carry off your children, so bring high quality insect repellent, or you will be very sorry.

Another thing: I downloaded the alltrails app to my phone, so I could have an idea how far along the trail we were. The app is supposed to work without data. Now I'm not sure if there was absolutely no satellite signal up there, or what, but the app was completely unreliable.

Beautiful easy hike! The trail follows a meadow all the way up basically, until you hit a few switchbacks to get up to the basin where the lakes are. The trail keeps on going up past the Lower Lake and goes by several smaller lakes until you reach the upper lake. There is another top lake above the upper lake that is absolutely worth checking out. The upper lakes hold lots of Trout, great fishing. If time isnt a concern, the saddle to the West of the upper lake provides amazing views of the Uintas and is easy to climb up. Highly recommended camping out! Bring lots of mosquito repellent too.

Amazing hike! Not strenuous at all for the distance. A friend and I did 3 days with a basecamp at Lower Red Castle Lake (LRCL). Explored the second day making our way up to Red Castle Lake(RCL). Once you get past LRCL there was more snow on the trail, but for mid June and all the snow Utah got this year it wasn't bad at all. We did not go all the way up to Upper Red Castle Lake because of the snow. I highly recommend doing more than an overnighter to get up to RCL and URCL. The views are AMAZING! Water is plentiful, so keep your pack light and don't carry more than a liter (and a filter of course). Talked with some folks on the way out on the 3rd morning who spent their time fishing and told us that the fish were plentiful.

If you begin at the trail head and hike to the Lower Red Castle Lake it is only 9 miles in. From there the trail splits you can either head to the East Red Castle Lake up or to Red Castle and Upper Red Castle Lakes. The hike is beautiful and follows a massive meadow most of the way. If you hike in the evening or morning you are very likely to see moose and deer. I also saw lots of elk sign in the lower areas.

Great fun. Hard hike for a pack of 12 and 13 but worth it.

This was my first legit backpacking trail, and it was a worthy one. Like most any destination, pictures do Red Castle no justice. But the name does. The mountain rises almost vertically from the surrounding valley, and is flanked by features that are impressive in their own right. Settling at the base after the long hike into high altitude is a reward typical of Sister Utah's legendary landscape.

This relatively inexperienced hiker found the trail very doable, if tough, for a three day trip, two days of hiking. The trail itself is a very gentle climb until the last climb to Red Castle base. If you've been going all day, this last climb can drain you quick. The destination had many campers and firewood was scarce. The Upper Red Castle Lake is a quick climb into the alpine zone, but one that left me pretty wrecked after day one. Nighttime this high up can get pretty cold but days are temperate. Water always accessible, so keep the filter on hand and shed the extra backpack weight. Bring your fishing rod for these healthy lakes and mountain streams. Needless to say, be prepared for war with the insect kingdom in the summer months.

Overall, the hike will be no challenge to experienced hikers, but offers the scenic payoff to make it worth seeking out this relatively remote destination. I would highly recommend it to hiking newcomers, who will receive the joys of a taxing foray into a very special place.

This trail being rated easy is true but be aware of altitude, it can sneak up on you and you can become winded if your not use to it. With that said, I have hiked all over the South West mountain ranges and the Uinta range is certainly a hidden gem! Absolutely beautiful at every step taken.

Took a church youth group up to Red Castle! What an amazing place. When you get to the foot bridge and can finally see Red Castle in the distance it is very inspiring, and gives more motivation to make it to the top! The hike does not have any big inclines (expect the small switch backs) but you are constantly on a gradual incline. I will be doing this hike again.

I did Red Castle back in September of 2015. It was one of the best experiences of my life. It was about 31 miles for us round trip. We made base camp at the lower lake then day tripped up to the upper lakes. We did it in 2.5 days and it was so worth it. I keep wanting to take another trip up there! It was so beautiful! And the trail really isn't too hard. Just one spot that switchbacks up on your way in that got a little difficult but was still great. Not too many people were up there. We saw some forest rangers working on some of the trail and they were very nice and friendly. The fishing was great at the upper lakes too!!

The hiking is not too difficult, only slight inclines, and one short switchback . The length is the only difficult part of this hike. Navigation is easy, water is accessible regularly. Not a whole lot to see until you get to the river crossing where Red Castle becomes visible. Amazing sunsets with Red Castle lit up with the Alpenglow. Lower RC lake glimmers, and fish rising all over the lake. I recommend passing Lower RC lake a short ways, and setting up camp there.

Day trip it to Red Castle lake for some good size fishing and amazing views. Also day trip it to East RC lake, for a different view and good fishing as well. Lower RC has plenty of pan size trout.

I have been here on several occasions, and will return again for another. It can be done in 3 days or more if you want to spend some down time. Fairly quick and easy TH access from the Salt Lake City area.
