I feel a great sense of accomplishment for my 10 year old daughter, who was the only kid on the trail to Chasm lake today. It was a great hike! So lucky to see a moose, out of nowhere, crossed the trail in front of us. It was scary and amazing at the same time! We waited a few long minutes for the clouds over Long’s peak to blow away. It got so windy but we came prepared and finished the hike.

Wow, this is an amazing hike! It was the perfect length and difficulty, for the occasional hiker. We started at 7:30. Got the last spot on the side of the road at the trail head. We got to the lake at 11. We had a some sandwiches. The hike took almost 6 hrs. We took 45min total for rest. So happy we did this hike instead of Twin Sisters.

I thought this was an alright hike. I’ve been earlier in the summer (June) and it was a beautiful walk in though we didn’t make it to the lake due to snow. Beautiful snow capped mountains and roaring waterfalls. Went again mid August and wasn’t nearly as beautiful walk in and the lake was nice but I’ve seen much more beautiful ones in Colorado. Probably best times are June and July and then fall which I assume will start in September/October.

Do you like rolling your ankle? Do you like busy trails? This is the trail for you then. The trail is clearly visible until the scramble to the top on the near peak, I stayed on the northwest side and found a route suitable for me without any issues. The worst part of the trail, other then being really rocky, was a stretch right after the washed out area. Lots of incline there. For me slow and steady wins the race. Great views from the top. I wanted to go to the second peak but I could see storms moving in so I left.

Great trail, rained on us but other than that it was awesome!!!

This was a great hike with breathtaking views... My partner and I started around 7:45 AM and reached the summit just after 9:30. We spent about an hour at the peaks before heading back down, and we reached our car around 12:00. We traveled at a brisk pace with a few stops to hydrate and catch our breaths. The air is thin and dry, so take your time, and (as always) bring more water than you think you’ll need. As many of the previous reviewers have stated, I would rank this hike as more moderately-difficult than hard. The trail has a slight incline most of the way with a few steep portions in between. It is rocky/jagged towards the end, at the summit, and on the way back down, so wear footwear that have protective soles lest you hurt your feet. The majority of the hike is in the forest- very shady and peaceful... Overall, this hike is a great choice for inexperienced hikers. Very doable, and the views will definitely not disappoint!

Climbed Longs Peak to celebrate my 50th birthday. Had a great group of friends and my son along. It was my first 14er and was an awesome experience.

nice quick hike up to the lake, not too challenging. awesome views at the top with a second lake if you continue which we didn't have time to do. the road up to the trailhead is very rocky so be careful driving. highly recommend.

they don't allow dogs so if you plan on bringing your first baby don't go here

beautiful, moderate hike, very crowded on the weekends. recommend arriving at trailhead before 730am. diamond lake has plenty of space for the masses but is busy by 930am. recommended!

Great hike! Definitely not too difficult... fairly trafficked on the weekend as of you approach the Lake. Lots of fun waterfalls and little features along the way.... If you’re doing this on a weekend definitely make it to the trail head by 7-7:15AM or you’ll be in a jam to find parking! We made it at 8 and parked about a half mile down!

A great hike! 4 stars instead of 5 because the first ~2.8 miles of the route got a little boring with all the trees (which were pretty! Just the same view for a while), but the view at the top was gorgeous. If you’re comfortable with it, definitely climb up the rock peaks at the top to get an even better view.

It took us just under 2 hours to get to the top, and about 50 minutes to get back down. However, we normally walk fast, and passed many people both ways. There were some pretty steep parts, especially halfway through, but nothing too difficult or unsafe. If you’re regularly active and in good shape, you’ll find this trail to be moderate and not “hard.”

this was beautiful at the top but it's definitely HARD

We thought we were doing the easier Kreutzer trail as there are two entrance points in the picnic area that you can get on the trail. It was a bit difficult for my 8 and 10 yr olds. Lots of burned and beetle kill trees. We will come back for the easier trail and the kids can build up their strength for the harder one.

Awesome! Incredible views. We camped in the Boulder fields. We booked months in advance, heads up! Morning hikers will wake you (we had some bozos playing music at 4AM hiking through camp, LNT is more than picking up garbage). Watch out for slick rocks if it rains. There were multiple water sources available. It is a popular trail. Be careful and follow the trail markers.

Did this on 7/23. Parked at 3:00 AM and was only headlamp I could see on the trail above tree line. There were several cars in the lot and many Long’s Peak hikers. Very windy and steep then when trail splits to Chasm it gets much easier. Views were breathtaking and this is one of my favorite hikes of all time. Add this one to your list and do it. Sunrise on Long’s was worth it all.

This ended up being one of my favorite hikes of the trip. It was definitely a challenge for me and my friend, two Midwesterners who have never climbed a mountain or generally even faced high altitudes before. The elevation gain and rocky terrain are brutal at times but definitely manageable, I think having hiking poles would definitely have made it easier. It took us 3.5 hours to get to the top, going at a reasonable pace and making frequent stops to let our lungs adjust to the altitude. The views at the top are astounding, especially if you scramble up to one of the peaks to get the full panoramic view, but the first 3 miles of the hike itself isn't terribly exciting. You are surrounded by beautiful huge trees for most of it though, so it was peaceful, and when we began our hike around 8:30 AM we saw several elk right off the trail. All an all I would definitely recommend this hike if you're looking to summit a mountain but are an inexperienced hiker.

My entire body feels like I got hit by a truck. Type 3 fun for sure. Make sure you know what you’re getting into before beginning your trek, though it’s really not as sketchy as others say it is, just be aware.

The hike up isn’t the most interesting, but the view at the top is definitely one of the best in the park. The trail gets pretty steep at a bunch of points, and the altitude can really get you if you are not used to it, but if you can, hike Twin Sisters.

Awesome hiking but not for the faint of heart. Be well acclimated before heading out on this beautiful hike.

Second time doing this hike. We got to trailhead at 6 am. Parking lots was full but I parked on the side along the entrance so didn’t have to park down the road. We got to lake at 9am. So took us 3 hrs to get there with minimal breaks. It was sunny and no clouds in the sky. Couldn’t hAve asked for a more perfect weather. There’s definitely an incline and last half mile requires scrambling up rocks but it’s so worth it!! One the best and moderate trails to do!

Absolutely beautiful - one of the best, if not the best lake hike in Colorado! My only criticism: far too many steps built into the trail. Steps needlessly make this a more difficult hike than it needs to be.

We arrived 6am Wed. Parking lot was full. We parked 1/4 mile down the road from the trailhead. The trail runs 8.4 miles roundtrip per Rocky Mtn Natl park website. It is a moderate hike, IMO (some will find it easy, some hard, depending on conditioning).

The final climb to the lake is a steep rock scramble, under 0.2 miles. it is generally intuitive and partially marked by cairns. If you can't ascend, you'll miss the lake but still be treated to the majesty and splendor that lies before you.

PLEASE, PLEASE, PLEASE respect the mountain and weather. I saw one person who had no water or backpack, and people hiking in sandals and one in overalls. Cotton is the worst thing you can be wearing if you get wet. Summer rains mean windy and temps in the 40s, or lower.

Be prepared. The rangers can suggest the right items.

Amazing climb, I’m 61 years old, have been doing CrossFit for three years and still got my butt kicked by this hike. This was one of the most exhilarating and foolish things I’ve done in my life (but truly rewarding). The weather was perfect. Don’t forget when you get down, you still have a six mile hike back to the car! Acclimate for a week, we went up after just 48 hours in Estes. Call me crazy, but I would do it again!

Excellent hike! We did this on August 7, 2018.

Standard Keyhole Route

I did this Wednesday, 8/8/18, from the Longs Peak Trailhead. I arrived in the lot around 2:20am and started at 2:31. There were probably 8 parking spots left.

As others have said, it's a pretty straightforward hike on a well maintained trail to the Boulderfield. Once to the Boulderfield (about 5am) I stopped to use the privy (two there, looked like they were building two more). The Boulderfield is well marked with cairns - even in dawn lighting conditions I was able to see cairns. I joined a handful of others in the lighting shelter atop the Boulderfield to wait on a little more light (and eat, change layers from jacket to vest).

I went through the Keyhole around 6am. It's where the real work starts. But seriously. It's no joke beyond the Keyhole - the hard work and sketchy-ness is just beginning. And it's both hard and sketchy. About the sketch aspect of Longs...listen to yourself - if you're too scared, turn around! But I was able to summit because I mentally focused on the next immediate challenge rather than the 100x challenges beyond (some of which you can see). I think people pysch themselves out by getting overwhelmed by all the impending difficulties.

I summited around 8:15am, spent about 15 minutes at summit, and was back to my car at 12:40pm-ish.

A few extra notes/thoughts:
-Per my GAIA GPS app: 13.93 miles, 10:06 total time, 4,871' ascent
-This is NOT a hike! It's not a good first 14er or one to take lightly. I'm serious - a slight mistake after the Keyhole can seriously injure or kill you (or someone else).
-Water. I drink a lot of water and went through 3.5 liters on ascent. I filtered water in the Boulderfield on the descent.
-Helmet. I'd estimate 90% of people don't wear one. I didn't (because I don't own one) but I'm not gonna lie - I wish I would've had one. Falling rocks/boulders would've just been one less worry in the Trough.
-Do others around you in the Trough a solid. If you cause a rock/boulder to come loose yell "rock" so those below you can be aware.
-I was glad to have a pair of light jogger type gloves for after the Keyhole. It's a little chilly in the shade but the rocks are cold and you'll be using your hands a lot!

This is definitely not a moderate trail. There's an extended area of narrow trail and you have to do some scrambling that's actually climbing. It's beautiful and challenging!

This and Mt Ida are my favorite RMNP trails. Really amazing and spectacular. Parking lot was full by 8:15am. We parked about 1/4 mile down the side of the road which isn't too bad. We had perfect weather with clear skies. No dark ominous clouds. Rangers were making trail improvements on a segment of the trail. Turns out they use horses to carry logs up.
Steady incline throughout entire trail with gorgeous view once above tree line. There is excellent view of Long Peaks about 1 mile out where there is also the first privy stop. Great place to take a break. Then the trail flattens a bit along a narrow path by the side of mountain with view of waterfall. The trail crosses on top of that small waterfall. At the base of Chasm lake, there is another privy stop. The last 0.1 mile was a bit of scramble up the rocks to get to Chasm lake. It was steep but that was also quite fun especially knowing that the lake is just above on the other side. Well worth the last bit of scramble.
Took us a little over 3hr to get up (with plenty time to rest and take pictures and absorb the surrounding scenery) and a bit over 2 hrs to get down. We spent a good 40 min by lake to have lunch and soak up the beautiful scenery. Highly recommend.

Amazing hike, started at 4am and got to chasm lake by 7am. Hike is pretty strenuous for someone from the flatland. Overall amazing views and would do this hike over and over again!

Started this hike at 7:25 this morning and finished around 2. Parking lot was full so be prepared. Used this as our practice for Longs Peak and I would rate this hike as hard, not moderate. First portion isn’t difficult. Once you get past the small boulder field and on the actual trail for Chasm it contains some pretty narrow areas but with great views. Some scrabbling is required to get up to the lake and that part of the trail isn’t marked very well. Very easy to get lost in that area. Have plenty of water and sunscreen because that sun can be very hot above tree line. Highly recommend using hiking polls too, I’m 20 years old and an athlete but the polls saved my legs a ton.

This was a nice, moderate hike. We had to park a ways up the road because there were so many cars.
We saw plenty of people on the trail, but many were backpacking, so the parking situation made it seem worse than it really was. The first mile or so is shared with the trail to Arapaho Glacier and shortly after the split is a lovely waterfall. We hiked up the waterfall area near the lake as well, and I'm bummed because we didn't realize there were more lakes! We didn't explore as much as we should have.
