Great hike. quiet and not too many hikers

Challenging! Could take casual hikers 4 hours to complete (more if you're not active). Give yourself the day and bring LOTS of water. More experienced hikers are still in for a challenge but a doable one.

Views are gorgeous, plenty of shade, and there's a cool map of all the visible peaks at the summit. The way back is relaxing and all downhill.

Meh. Nicely built trail. Views at the top were pleasant. But the road-crossings made this feel like I wasn’t really off the beaten path. I never found the ladder?! And I didn’t find the trail to be nearly as hard as others describe. I carried poles but never even took them out of my backpack.

This was my favorite hike ALL summer. Not heavily trafficed, closer to Denver, and stunning views the whole way up! I highly recommend. Make sure you arrive early so that you don't have to hike up to the trailhead. I believe there is public transportation that brings you directly there as well - maybe look into that.

This is a moderate intensity 3 to 5 hour trail depending on how rigorous vs. leisurely you want to be. I've hikded this trail in both directions. Ascending via Amphitheater is a steeper incline, and more gradual descent via Ranger and Gregory Canyon, compared to vice versa. I recommend this route if you're looking for a more challenging climb that's gentler on the knees coming down. There is plenty of shade and some open spaces. The view from the summit is beautiful.

Absolutely beautiful hike!!

I hiked to the bottom lake on 15 September 2018. I probably should not have. wasnt ready for this trail. lol. know your limitations, then pass them by. awesome hike. so beautiful. friendly people along the way. 3 hours to the first lake for me. 2.5 hours back down. my goal is to get down to 1.5 hours going up. definitely recommend this hike. dont quit. the view is worth the a fib. lol

Great trail, but definitely a workout with lots of steep inclines and rocky terrain to climb up and over. We went clockwise starting on the Gregory Canyon trailhead in the parking lot and then meeting up with the Flagstaff trail. Saw some mule deer, but more importantly, heads up for bears! Not-so-little guy was greeting people at the parking lot towards later afternoon hours, so be aware. Also parking is very limited and there is a $5 fee if your not registered in Boulder or have a pass.

This is one of the most enjoyable hikes I have ever done. Gorgeous views the whole way. Mild ascent to the first lake followed by a short (but steep) climb to the upper lakes. Hiked this trail on 9/15 to enjoy the fall colors.

Good hike...go early as it gets busy with hikers. make sure you wear your hiking boots. it's a bit rocky in places.

Great trail. We hiked in and camped at Lawn Lake Campground. Had the lake to ourselves. Didn’t see many hikers on this hike because of the length. It’s a tough hike if you’re not acclimated. The breathing gets harder at 11,000 ft. Approx 18 Long switchbacks up. The elevation gain is rapid and rocky. Overall, it was amazing and a breathtaking adventure.

My husband, dog, and I hiked this trail today. First things first, this trail is wayyyyyy more than advertised. We clocked it at almost 9 miles with our GPS watch. Besides that, Ice Lake was absolutely beautiful - blue and full of water. The scramble further to island lake had some sketchy spots that I would have loved to use trekking poles on. Island Lake itself wasn’t as pretty as Ice Lake but still cool I guess. The water was kind of green and not nearly as striking as the ice blue water.
As far as the trail goes, it starts out in a nice pine forest that goes in and out of sunny aspen meadows (some of the leaves already started turning yellow which was beautiful!). Finally you get to a clearing where it flattens out a little followed by a pretty long and difficult climb to Ice Lake. The scramble to Island lake was less than a mile.

Amazing view at the summit. The last half mile or so is brutal for low altitude lungs. It was worth it though. Be forewarned, taking Greenman and back up via Ranger adds a couple of miles and some intense inclines to get back to the top. We ended up being gone for about 5 hours adding that loop. Take breaks and snacks. It's an amazing hike.

Just did this trail today and loved it! The views are amazing! The beginning is pretty easy but it is challenging at the end, but overall a great hike!

Waterfalls everywhere on the way up, ice lake was gorgeous...I’ve never seen water so blue. Island Lake is a quick scramble over. We took the loop down...it was steep! I’m glad we took the trail to lower basin, ice lake, island lake...because there is a spot where the trail cuts and you can hike to island first. I would not recommend. We saw a bobcat on our way out. Can’t wait to explore more in the area. There is a camp ground at the base and a few places to camp if backpacking by the lower basin. (Hiked mid August)

This was my first ever backpacking experience. Nothing will make you feel like you over packed quite like this incline! It was definitely hard but so worth the trek. We went the Thursday and Friday before Labor Day to avoid the weekend camping crowd. The views and feeling of seclusion was a great way to round out summer. You can’t have fires up in the campground area, so be sure to pack some fuel for a camp stove and pack layers. It was fairly windy most of our stay there, but being in the tent at night was plenty cozy.

This hike was beautiful! It was my first backpacking trip and I was not disappointed! The day I went, there was a chance of a storm... luckily there wasn’t. My friends and I truly enjoyed it! Awwwww sooo fun! The incline was a little strenuous, but nothing too difficult!

Busy area and trail but very beautiful. I thought the atv's were loud until a car full of tourists showed up around 6 a.m. On my way down, a group of young white people, whom thought I was out of earshot or just didn't care, started making fun of how I looked. Sad way to end the day but everyone else I crossed trails with earlier in the day, was very kind.

Fantastic for a short hike, quick elevation with a family!

Terrific hike. Best I've done in the RMNP area. Not too strenuous on this longish trail, so you can get the distance in, which makes it a real hike. Once you get away from the half milers as I call them the trail is very quiet. Rewarded with views as soon as trail starts and this continues. Even in wooded areas everything seems open and light. Go for it you won't be sorry.

This a nice trail without too many rocky parts. My GPS shows 12.8 miles. Did this hike on a Saturday starting at 8:20am. Very few people on this trail but saw a lot of fishermen at Betty lake.

Great hike. Went up to the pass. The trail is very well maintained until the trail goes above the vegetation line. It's a little rough above that but very doable until the pass.

Good route, good views from top & a few other places, good weather today, good hike.

Fantastic trail. Like someone else said, it’s a great leg workout going up. There was a deer just off the trail and didn’t mind us being there at all. It was a great experience.

Outstanding hike. First part is a pretty decent incline but after mile 2 or so it isn't too bad. The climb from the lower lake to the second lake is, once again, a pretty decent incline but the payoff of the view makes it all worth it. Lower lake is aqua blue and crystal clear. Upper lakes are still amazing but totally different feel than the lower. Ran into quite few groups of hikers but never felt "crowded" by any means.

Nice short and relatively easy hike! Took us 45 min to get to the cave. The views from boulders are great.

Beautiful hike!

Great hike. Arrived Sat morning at 10 am had a few parking spots available. We hiked past the 1st lake to the overlook above the lake. Amazing views! Steep incline thru most of the trail. Took us 5 hours to complete.
