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.

Amazing trail with plenty of water view and river trail!

So beautiful

One of my favorite hikes in RMNP! The views are incredible! If you are going to hike Flattop you might as well go to Hallet Peak. Maybe another half hour push from Flattop but well worth it for the unobstructed 360 views of RMNP.

Finally found parking at Glacier Gorge Trailhead. Hiked out to Alberta Falls and then headed back to the trail junction and headed to Bear Lake. Walked the .5 mile loop around Bear Lake. Took the shuttle back to Glacier Gorge. Absolutely beautiful hike. Took a lot of pictures. Not a pro hiker. Uphill stretches are tiring but well worth it.

Not an easy hike but a mid-40's couple from Denver took their time and got to the top in about 3 hrs. Some of the most amazing views the park has to offer. Surprised how many other people were on this trail, most younger than us and blazing by. Oh well! We were beat afterwords but loved this hike. May take it all the way into Grand Lake next time.

This trail was even better than we expected! I would actually consider the destination to be not just Flattop Mountain summit, but also Tyndall Glacier, which is incredible! The views were amazing and we saw lots of pika and marmots as well. The Emerald and Dream Lake overlooks are a nice bonus! We didn’t try hiking up adjacent Hallett Peak this time but will try it on a future trip. We hiked this trail on August 11, 2018.

Took about three hours to complete, two out and one hour on the return trip. Took upper path on the accent, and descended via the lower trail. Great views almost the entire hike. Advise getting to the trail head pre 7am as parking is very limited on the Old Fall River Rd near the trail head.

If I were you, I'd do one of two things and neither is just summitting flat top. If youre up for a slightly longer hike, continue past flattop to hallett where the view is 10x better. It only took us about 45 minutes round trip to do this extra bit and we were very glad we did. If you're less up for it, just go up flat top past the two lake overlooks and after you get above the tree line. The views there are very cool and the other reviews are right - the summit views of flattop itself are a little anticlimactic. Still a beautiful hike if you're up for a pretty uphill hike in the sun! Loved it

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.

If you’re not parked in the parking lot (which fills up really early), be VERY careful where you park as they tow cars parked on the side of the road on the side of the yellow curvy road sign that is closer to the trail. As per an officer, you’re ok if you’re not parked after that sign (on the way up), not in front of a no parking sign, and have both wheels completely off the road, i.e. to the side of the white line.

Very easy beginner trail but so beautiful everyone will want to go. I walked Bear lake trail first then took Alberta Falls Route. A lot of people on weekends.

This was my first hike at RMNP, and it didn’t disappoint! My husband and I started at the bear lake trailhead, took a portion of the flattop mtn trail then when flattop mtn trail branched off to the left, we continued straight on the fern lake trail. We took the trail for a few miles and turned around right before two rivers lake. The incline was a good, challenging pace, not scrambling but not flat. We are beginner to intermediate hikers so this was perfect for us. The higher you get the rockier it gets on the trail. Some nice streams along the way and while it started off sunny and warm, it cooled at bit on the way up while in the pine forest. There was a portion of the trail that is next to a mountain that is nothing but rocks, so we slowed down a bit on this. This portion was also very sunny, but did not last long. Did not see any wildlife. I would do this again and next time probably go farther! Beautiful views along the way and not too crowded. I noticed the farther we went on the trail, the less foot traffic we came across. We arrived at the trailhead around 8:20am and it was full. Was able to snag a spot though. Might consider arriving a little earlier next time. First time at RMNP and I’m hooked. I never want to leave!

Pretty darn good hike. We parked at fern lake trailhead and hiked to the bear lake trailhead and took the shuttle back. Note that the shuttle does not go all the way back to the fern lake trailhead. You will still have 0.7 miles to get to the actual trailhead. Overall it’s almost 10 miles and about 2700 ft gain in elevation. It would be a lot easier to go bear lake to fern lake. Bear lake is higher so the climb is much less daunting. Parking is more difficult at bear lake. Either way the scenery is gorgeous and the streams and lakes are beautiful as is fern falls.

I combined this trail and the Emerald lake trail, for totally about 4 hours. The scenes along the trail are very good. Maybe because the elevation here is too large (~3000m), I was very tired although the trail is not hard.

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.

Liked it better than Flattop mtn, Hallett Peak, and even better than Emerald Lake. The least crowded hike in the Rockies so far with the best views going both ways on the trail. Amazing views at the lake. Wish we would have done the social trail to Helene Lake on the way back...next time.

Hike to Alberta Falls was easy and nicely groomed but heavy foot traffic. Attempted trail to Mills Lake but ran out of time. that trail was equally nice. On way back hiked to Bear Lake (all up hill) but very nice.

I hiked this both from Bear Lake trailhead and Glacier Gorge trailhead. I preferred entering via Glacier Gorge trail because it was a little more scenic. The difference - hiking from Bear Lake trailhead, you'll descend for quite a while until you begin ascending toward the falls. If you start from Glacier Gorge trailhead, you'll be ascending. This starting point will offer you more cardio.
The walk to the falls is lovely and offers you views that span for miles. Gorgeous. ...but even more gorgeous if you pass the falls and hike to either MIlls Lake or Loch Lake. Trust me, it's worth it. :)
The reason why I'm giving it only 3 stars is for a couple reasons - it's populated with tourists who aren't equipped to hike to the falls. Point being, they're a hazard, so watch out. Secondly, although I thought the falls were lovely and the sound soothing, I thought they'd be grander. If you hike on towards one of the lakes further up the trail, you'll continue to parallel the falls, which is nice because that sound of rushing water accompanies you.

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.

Great trail, with diverse landscapes and reasonable uphills. However I recommend to do an extra effort and continue to Bear Lake instead of coming back. This would imply a “hard” hike, taking into account the uphill between Fern Lake and Lake Helene. But it pays off!: You don’t repeat landscapes and you will experience the rocky world of the RMNP, with vistas of some glaciers. And you arrive to the crowded Bear Lake, where the bus is waiting for you to bring you back to Lake Fern trailhead. Give it a try!

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!

Lovely, easy trail. The falls are just beautiful. Can get busy, but there's plenty of room for everyone to move around and enjoy. Keep going up to Loch Lake Trail, it's more challenging and worth the hike.

Beautiful views. Definitely a must see

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.

my pedometer says 10 miles, and 3500ft vertical. Another Thing To Know Is That This Is A climb, not a hike. you are going up, at least 30 degrees, the entire time. A hike is at least half flat.

storms hit this mountain every day, yes, every single day. I don't Care what your weather app says. bring layers, be prepared for rain and hail, thunder if not lightning. there is a shelter hut by a privvy about 75% of the way up, can't get in but can hide in doorway.

Devote 12 hours to this, bring plenty of food, I recommend caring water cantina and filter, as carrying water up a mountain will be incredibly hard. plenty of people take 2 days on this hike, its a serious physical feat.

Views on route were breathtaking! However, as others mentioned, the view from the summit itself isn’t the greatest given how flat it is. Many hikers continued to Hallett Peak - and it may be worthwhile to plan ahead and give yourself more time to include the second peak.
