Very hard when you do the loop clockwise. 1 mile of non stop steep climbing. Rest of loop is much easier. The view from the top is worth the effort.

Great hike! Make sure you do the full loop. Beautiful views. The last couple miles of the trail follow along the river. Fairly easy incline.

Great and challenging hike. Good elevation gain. Was able to do in about 3 hours. Quite a few trail runners, decent amount of wildlife too. Awesome views! You do have to pay for parking on the weekends, fyi.

Fabulous hike. Sturdy views, etc. highly recommended.

Great trail!

My girlfriend and I hike to Jasper's lake 5/25-5/27. We intended to do the whole loop but there was to much snow. Snow made it a little miserable but also fun. At some point there wasn't a trail just branching paths of foot prints. We got lost two or three times but nothing a little back tracking couldn't solve in a few minutes.

The hike to Jasper's was gorgeous. Will probably hike the whole loop at some point but when it's warmer for sure.

This was a beautiful hike. My wife and I did it in about a day and a half. We hiked it counter-clockwise, starting from Hessie. We left our car at 12:30, and camped at Devils Thumb lake that night, arriving around 6:30. The next morning we were on the trail at 6:30,and back to the car at 2:30.

As some others have said, I felt that the north half was the prettiest, but the whole thing is great. Also, aside from right near Kings Lake, and the first mile of the trail, we didn't see too many people.

I would definitely do it again. And splitting it up the way we did was nice, because we didn't have to do the whole climb up to the continental divide in one day.

Pretty easy hike as far as elevation climb goes.. it is mostly flat with only small inclines and declines. The burned trees don't make for the prettiest sight but the lake full of lily pads is beautiful! Probably not my favorite hike but seemed family friendly as we saw lots of families with very young kids hiking. The creek and boulders are also a neat part of this trail.

We started out early (7:30) and avoided most of the crowds. Headed out from the fern TH to make the finish easier - better to walk 1 mile on a dirt road when it’s cool and empty. We saw wild turkeys, elk, marmots. The lake is nice, but the pool is way better. Coming down along the Big Thompson river was crowded. Loved it. Done with an 11 and 13yo.

It’s a very nice trail !!

It’s a very nice trail !!

Beautiful views: mountain-backed lakes, harsh ridge lines, and wildflowers. Well-marked trail.

We hiked clockwise, three days, two nights -camped at Bettie Lake and Devil’s Thumb Lake, felt alone at both. Jasper Lake looked like a popular camping spot, and there was a site by the stream right before the off-shoot to Bob and Bettie Lakes if you don’t want to leave the loop. We were skinny-dipping at Devil’s Thumb and realized there was a lone fisherman across the lake getting a great show, haha, but otherwise, camping was very peaceful.

I was thankful for layers because it was really hot during the day, but surprisingly cold as soon as the sun dipped. We made Nalgene hot water bottles to supplement our 20* sleeping bags.

We hiked mid-week (Aug 8-10) and saw more hikers and trail-runners than backpackers. Some people struggling, but then also an older couple of women crushing it, and a Dad with two young kids. I’m a beginner with a heavy pack and ended each day smiling.

Brought my 35lb pup - she wore off her front pads chasing marmot in the rocks... which wouldn’t have been a problem if I had kept her on leash. She loved it. Didn’t see many (any?) dogs out towards the peak, but lots at the trailhead. Leash definitely required for the first bit.

Elevation is no joke, but plenty of places to refill water, so keep drinking!!

Side note: we stopped in Ned on the way home and ate at the Thai restaurant - killer $10 lunch deal!

Nice trail. Took me about three hours. Great views all the way throughout.

Arrived at 5:15 am on Saturday and there were a lot of cars parked on the side of the road but still plenty of space. People can't seem to agree on which way to go- I decided to go counterclockwise and I'm very glad I did.

I have been up to Jasper Lake a couple of times but this is the first time I tried the loop. In my opinion the north side of the loop is more scenic. It's best to do it in the morning when the lighting is better and you still have energy. Also I like steep inclines more than steep declines as they're more exciting and less stressful on the knees. Saw a bull moose about halfway up to Jasper Lake. That was pretty terrifying as he was only 25 yards or so off of the trail hidden behind some trees. I snapped a quick picture and got out of there.

The trail is pretty easy. The distance is the hard part. I was feeling pretty haggard on the last 3-4 miles. Got back to the parking lot a little before 3PM. I probably could of finished at 2 if I hadn't of taken so many pictures.

Overall an awesome hike! My favorite one so far

Hard but the views at the top and along the way are gorgeous! Saw my first snake on the trail which was a little spooky and there's plenty of signs up warning about mountain lion and bear spotting so keep your guard up!

Oh boy, we saw a black bear cub on the amphitheater trail. Luckily a trail runner came through and scared it off. Other than that the trail has its difficulties in terms of large steps going up to and after the peak. It also started raining on us so i’d prefer to try again on a sunny, bear free day.

One of my go-to faves, especially when preparing for the next 14er.

A 4 outta 5. The lake and Bridal Falls made it worth it. The back part of the loop is indeed hot but it's a little ridiculous to complain about it!

I got a late start with my 19 month old daughter - left the Lumpy Ridge Trailhead at 830am on a Monday (7/30/18) and did the loop counter clockwise. I ended around 330pm. I gotta be honest, it was tough sledging on the last ascent on the backside of the loop. Mostly because I was carrying my daughter in a pack which weighed ~47 pounds and I was getting worn down.

A few things:

-Per GAIA GPS: 13.08 miles, 2,790' ascent, 7:18 hours (1:36 of stoppage time - lunch at the falls, water filtration, diaper changes).
-I was surprised at the lack of people. Saw ~8 people between TH and Gem Lake. Probably ~5 between Gem Lake and Bridal Falls area. ~12 around the Falls. ~10 from Falls, around back part of loop, and TH (mostly within a mile of TH).
-Water is pretty much everywhere. I refilled near the Falls.

You need a discover pass just FYI!

Once again you can never tell what the rating system AllTrails uses.i would say the rating of moderate doesn’t seem to fit. I would rate the climb in to be difficult. The distance to be easy and the descent technically challenging. Morning rides are less packed and 5pm everyone and their brother/sister hits it after work. High traffic for sure on weekends and evening. I’ve seen lots of people carrying their bikes up hill and going ass over apple cart on the descent. Some may say it’s the line you take. There is some truth tho that.
I would tell my friends to ride it in the morning. that it’s lots of fun on the down hill and the climb is a challenge. It’s a trail short enough to do laps. Enjoy!!!

This trail is quite difficult! My husband and I wanted something hard-but man this kicked out butts! At one point you’re climbing up a ladder...so there’s that. The views were beautiful. The one thing that was a bummer-at the top there was an unusual amount of flying bugs...like a ridiculous amount. It made the summit a bummer and we didn’t spend much time there. But we would def do this hike again!

My husband and I tried this one at a friend’s suggestion. The burned trees are sad to see, but the meadow is lush and there is a lot of healthy vegetation. The first couple of miles are a gradual incline, rocky in places, but manageable. The lake is a little over two miles in and it is gorgeous! It’s covered in lily pads. After the lake, the trail winds through some wooded areas and the Thompson River becomes visible. It’s also very pretty and there are multiple places to rest, have a snack, and dip your toes in the water. About a mile and a half before the end, there are several large, random boulders. We saw several people practicing their bouldering skills. All in all, a great hike with lots of photo ops.

Wonderful trail. Great wildflowers. the hike is a great start. slow build to a good climb and around. Don't forget that you start at either cub lake trailhead or Fern lake trail head and end at the other one. they are a mile apart to walk between. wasn't too crowded in the morning. must do hike.

Good and strenuous hike. The 3/4 mile steep section was fun and tough up and down (recommend hiking poles). Enjoyed the shade during that section. Exactly two hours from tail head to peak (with several photo stops) and about 1:45 down. Nice 360 views from the peak.

I absolutely love this trail. Wide open plains, trails around the foothills and narrow trails through the trees up into the mountains. Riding through the foothills of Lyons is just so beautiful. I heard watch for rattlesnakes on the rocks by the trails but haven’t see any. I love it here!
IMO horses need boots or shoes for sure through some of the really rocky areas. It’s mostly smooth sailing but I still wouldn’t go without them. Parking for trailers is an easy pull through.
GPS to the trailhead was off for me it was about a mile further up ahead on the right. Almost missed the turn into the trailhead. Because I thought I had past it. I pinned it for the next time. Watch out for trail closures on the website before heading out. Closes a lot because of muddy trails after a rain. Approx 9 miles. Happy Trails!

good hike great view of boulder at the top of bear mountain

Did this on 7/21/18. Get to trailhead early! Do this loop clockwise
so you go by the meadows first increasing your chance of seeing elk and deer. Lots of wildflowers, moderate elevation gain and great views at the top. Look for wild raspberries- yum! Nice lake and some aspen groves. The hike back after the pool is crowded and mostly flat.

First third is easy! Second third is somewhat rocky and begins the incline. Last third is fairly steep and very rocky. Wonderful lake...quiet and peaceful.

I won’t lie this hike is pretty legit! Easy and enjoyable walk the first couple miles and then it gets gnarly!! Totally awesome, only made it to the saddle and got turned around due to weather. Super cool trail and I’ll definitely be back to finish it! Check out my photos to see where it gets tough!
