Beautiful lake. Lots of hikers but they were very considerate. Lots of big rocks and up hill a long way. Should have shoes or boots. Water and mud crossings. Not for beginners. Need a conditioned horse. Beautiful scenery.

It is a uphill hike all the way to the falls. Somewhat rocky but well worth it once you reach the top. The hike back down was extremely easy but the hike there takes a toll

I'd rate it as moderate for anyone in moderate shape. I'm 61 years old and didn't find it too stressful. There is a path and a separate parallel dirt road. If you stay off the road, you won't be bothered by ATVs/Jeeps. Footing is a bit challenging over the rock field sections. The lake is beautiful and I am told offers great fishing.

I first hiked this trail with my hiking group. I was amazed at the diversity of the trail and beautiful waterfall at the end. I took my husband, kids and friends the following year. Slightly strenuous at the beginning then levels out. Be sure and eat lunch by the falls and enjoy the mist... it’s heavenly.

Very nice but a bit busy, the hike itself it’s not a piece of cake but it’s not crazy hard either, you have to consider that it’s a steep hike up, just take your time.
We saw solo hikers, families, definitively dog friendly.
Took us about 1 hour and 40 min to go up, gorgeous views, we stop by the waterfall to have some lunch and then continue our way down the loop. About one hour down for us.
Totally worth it !

Pretty packed but a great trail with water along the way

Only giving 2 stars, because the guide information was wrong. It is a 20 mile loop (according to my GPS), not 15.9, so a bit on the strenuous side. Probably would’ve made it a backpacking trip instead if the information was correct. Very long day hike, but very beautiful and worth it.

The loop as a whole was a decent hike with some spectacular sections along the way. We did this in 3 days and 2 nights with very little planning because it was our plan B.

Day one (6.5 mi): Hiked up to Brown's Lake, stopping at the waterfall on the way. The waterfall was definitely the highlight of the day although the lake and valley between the towering mountains came in a close second. The mosquitos were absolutely terrible.

Day two(7 mi): We hiked up to the pass where you have the option to hike one more mile and 1,000 more feet to the top of Mt Antero. The hike up to this point is pretty brutal in some spots. Most of the hiking around this area is done on roads shared with 4-wheelers and jeeps, hence the 4 stars. We finished off the day by hiking down to a camping spot near the creek.

Day 3 (3.5 mi): Very easy and nice hike out for the final day. Pleasant single track that made the final day enjoyable.

I love this trail! It’s one of the best trails I’ve hiked on in Colorado. My husband and I’ve hiked it twice, once when the Aspen were golden and with a dusting of snow on the ground. It’s got beautiful scenery, a variety of terrain, and a lovely waterfall at the end.

Loved this trail. Moderate is the right description. Missed the turn off for the falls but the next mile and a half was great views. Hit the falls on the way back . Spectacular falls. Water is so pure.

First mile and half is a pretty steep climb, gets a little easier after that. Good coverage from aspen trees. Big payoff at the end with the falls. Lots of fun log creek crossings. I hiked this in May 26th with my 8 year old son - falls were flowing good.

Beautiful hike, the waterfall is worth it! We enjoyed it so much we continued hiking the additional 3 miles to Brown’s Lake!

The trail is great. Did it with my wife and two kids who are 9 and 6. They loved the trail also and really loved the falls at the end. We also took the dogs 12 and 3.

Vacationing from Kansas City, MO. Loved this trail!

GREAT hike. Trail marked well. What makes hiking worth it: getting to top, all to feel so small in this HUGE world.

Sorry Folks...despite all the other reviews...this trail is not Moderate...it should be rated as difficult and hard! Very rough terrain...lots of boulders and rocks to maneuver going up!! You are continuing looking down to make sure you don't trip and or go over the cliff rather than taking in the view! Once you do reach the waterfall more terrain...yes the fall is pretty but not worth it in my book...I've hiked many trails in Colorado but this should be deemed for the most experienced hikers! On the way down is just as treacherous as the way up!

Great hike! Steep start then levels out. Great falls!

Did this trail on 6/13/18 tool my wife and I around 1 hr and 50 minutes to get to the top and another hour to get back down. I would say the difficulty is accurate. This has been one of our favorite hikes, the scenery is beautiful with a good payoff. We met a few groups of people along the way and a little bit of snow towards the top but nothing extreme. I recommend having some lunch and coffee overlooking the lakes.

My 2 sons and I just got back yesterday 6/16 from an overnight at the lake. We got a really late start but still made it to the lake before 6 pm. The 3 miles from the falls were really hard work with packs but well worth it. The area is absolutely beautiful and so serene. We picked a spot right by the water and thought we were completely alone until the next morning when we took a hike beyond the lake. The water was so clean it looked crystal clear even before being filtered. Breathtaking.

We hiked this with our kids and small dog. The waterfall was gorgeous! We loved hitting the creek in a couple of areas on the way. The views are great. We hiked in and out within 4 hours. Bring plenty of water as it gets a bit hot in some spots.

This was a beautiful trail. It was a little bit challenging coming from Florida. I mapped 6.2 miles in 2 hours 40 minutes. The view of the lakes was incredible. I would definitely do this again and bring lunch and eat it overlooking the lake.

Hiked this over the weekend with kids aged 8/9/10 and they all loved the waterfall. I love the varying terrain of this hike and the nice climb to start. The drive to the trailhead is easy and the views from the trail are phenomenal.

Definitely marshy and snowy in parts, I found myself losing the trail a couple of times on the way down. But beautiful hike as a whole - I’ll be returning with my camera soon!

great moderate-easy hike. recommend it. Only made it tl the falls and it's amazing.

let's start off with.... I didn't die :)

this trail is not for the faint of heart. backpacked up with my 6yr old. started off late and only made 4 miles in first night which worked out great for second night as we were first to the lake to pick our spot. as others have mentioned, good spots up front, but if you want privacy you can walk an extra 5 minutes to the back. lake was windy but plenty of fish and relatively quite. there it's a 4x4 tail at the back side of the lake. think for next visit with rest of family we will drive up.

trail starts at with a good incline and ends with a good incline. pack light if your staying the night.

Great trail! Very well marked and we'll maintained. Easy out and back to the water fall, which was incredible! Loved how it was partially covered, then bits if exposure here and there. Nice variety.

First off, I’d just like to state that there is a sticker in the St. Elmo General Store that says “I survived the Grizzly Lake Trail!”, so if that doesn’t tell you something about this hike, I’m not sure what will.

I am young and mildly out of shape, but the first mile of this trail was absolutely hellish. I took about 2 hours (with 2 older women) to reach the lake, including plenty of rest breaks in the shade. Keep in mind, about a year ago I had an ACL replacement, and my knee was swollen up a half mile into this hike. The view at the end was definitely beautiful, but I wouldn’t attempt this trail again till I was much more physically fit.

The majority of the trail is a loose boulder field in the open, so wear plenty of sunscreen and bring lots of water, because it was very hot around midday. However, it was very interesting because there are lots of open mining pits (careful!) and old cabins to explore.

My main take away was this: this trail requires a physically fit person who is prepared to walk the majority uphill and who can carry lots of food/water. Do not attempt this if you think you might be unprepared, there is no cell reception and it is very lightly traveled.

Incredibly beautiful waterfall. Easy trail 3 miles out with a few marked T-intersections (pay attention at the intersections or use your GPS). Our dog loved the creek crossings. A few people on Friday afternoon.

Great hike for a moderate trail. Quite a few large sections of snow on parts of the trail in the upper half. Lost trail a couple of times. Trail also muddy in spots from melting snow. These issues created more of a workout. But it's all about the adventure - great hike with fantastic photo opportunities.

What a wonderful hike! As many have mentioned, you will have plenty of company on this hike. I now know why it is so popular, because it is wonderful! All the scenery changes, not to mention the waterfall, made this hike very enjoyable, I love a good goal at the end of a hike! As others have mentioned, most significant grade is at the beginning. Once you enter the forest, it is what my wife would call a nature walk, not tough at all. Will certainly return...with friends!
