Great views of the Yellowstone Canyon on this. While there is the trail that can be walked in its entirety, there are also parking spots at various places so you can make this work however you please in terms of whether you want to hike it or just stop at the designated viewpoints. I went as the sun was setting and it was incredibly beautiful.

I have done this Mystic Falls loop three different times of the summer. Mid-to-late June is the best b/c the snow melt is awesome; the water is roaring; and there are small waterfalls that are very nice that are gone by mid-July and thereafter. Every time I go back to YNP, this hike is a Must. A repeat.

Well worth the hike will do again

I didn’t hike the trail —we only went to the touristy section where you can see Inspiration point and the canyon. It was amazing. So beautiful. Probably one of the prettiest places in Yellowstone.

Grateful our Hiking group took the time to see this even though was w little crowded. Go early for fewer crowds.

Make sure to do the entire loop. If you start low, keep going up and up and up after you pass the falls. It’s a peaceful hike and chances are you won’t encounter many others. The view at the top is great.

Wonderful sights!

Short mud pot trail, there are much better areas to view geothermal activities. 3.8 miles/6 km south of Norris Junction, the lower portion of this colorful hydrothermal area is wheelchair-accessible. The upper trail to the mudpots is steep and rough, and not recommended for visitors using wheelchairs. Fountain Paintpots is a better viewing area.

Beautiful trail with amazing views. Hiked parts of it in July 2017. You can get right next to the head of Yellowstone falls and/or take some great photos at a distance as well. Not for small children.

great trail.... away from all of the people in YNP... bring deet if hiking in summer.. tons of mosquitoes and flies.. a little difficult when hitchhiking to the trailhead... I hitched from old faithful to the start of the dirt road... then off and on until I got to the trailhead... I think I spent more time hitchhiking to the trailhead than on the trail! haha .. fun trail.. wide river ford at the beginning..

We started the trail from Wapiti Lake Trail head since the parking lot and part of the trail near Henry’s Trail is closed for renovations. It’s was an easy hike to Clear Lake which was stunningly beautiful, definitely worth seeing. You can continue to Lilly Pad Lake and or Ribbon Lake but the scenery wasn’t as nice past Clear Lake. We ended up turning around before Lilly Pad Lake.

Great hike, great views all the way to the top where Artist Point is. There were even artists painting up at the top. Our original plan was to take the Canyon Rim North Trail to Inspiration Point but that trail was closed. This trail had the opposite point of view from inspiration point, you could see inspiration point on the other side! Very happy we chose to do this hike since we couldn’t do the other. Don’t miss out on this hike! Highly recommended.

I have always come in from Fish Lake. This trail features three river crossings, which for me adds to the fun, and skips the elevation gain of the Grassy Lake trail. About the same total distance. Hardly ever meet anyone on this trail.

A good change of pace from the geyser basin boardwalk trails. No crowds and a surprisingly nice waterfall to view. We hiked to this from the Old Faithful Lodge so it was a little longer than the stated 3.4 miles.

Four stars because of the awesome scenery! Trail was closed in 2 places, so was unable to hike the entire thing. Pretty easy hike with lots of people.

An easy hike but one of the more enjoyable ones that we did on our trip. Gives you the feeling of being out of the way without having to go too far out into the back country. We ran into a few other groups but everyone was very considerate. Bring a camera and enjoy the falls!

Easy trail for the whole family. Glad we took the time to go and see the falls. Beautiful scenery. I would call this more of an easy walk with a few little hills here and there. Two trail routes, one that goes to the base of the falls and one that goes to the top. Both are beautiful.

What a great waterfall. so worth the hike. Went to the lower part of the falls

Great hike, came back in the dark, couple creek crossings, one big one . The water at Ouzel Pool was amazing. Heading back before the season ends. Falls was beautiful, the pool was the best.

The scenery is worth every step. We started at Cascade trail instead of Grassy Lake and did the Terrace Falls trail then came back to the trail sign and headed up Union Falls. Terrace Falls followed the river so the scenery was completely different than Union Falls. This made it a total of about 19.5 miles. Bring a swim suit and plan on swimming in the warm spring just a .3 mile detour to the left before Union Falls. At Unions Falls there is a trail that will take you down to the falls so you can get right next to it. Worth every step. 1 major river crossing. Heading back the cold water felt AMAZING on sore muscles. Even though this is not a steep trail plan on it taking you twice as long to get back because it is so long.

many portions of the trail are closed for repairs boooo

I would rate this trail moderate, not hard as in the description.

Coming from the Ashton side, there's about 25 miles on dirt roads, and it will take some time to get there. About one mile in, you will need to ford the Fall River. Depending on the time of year, the river can be anywhere from knee deep to thigh deep. As far as water crossings go, this one isn't bad at all. Trekking poles help a lot.

Beyond that, the trail is pretty straightforward, kind of rolling up and down the hills. There's generally plenty of shade, and plenty of spots to filter water.

The falls, located about 7.5 miles from the trailhead, are worth the effort. This is the second largest waterfall in Yellowstone, and is named for the two streams that converge at the waterfall.

Expect mosquitoes and horseflies from late June through early September (bring plenty of bug spray). Bear spray is also recommended.

Like another reviewer mentioned, this trail covers pretty much all of the features Yellowstone is famous for in this relatively short and easy hike. We saw lakes, meadows, forest, geothermal activity, and stunning views of the canyon all within less than 4 miles. Would highly recommend!

Awesome! The hike back is harder than the hike in. Easily one of my favorite hikes!

Great hike, beautiful scenery, lots of raspberries along the trail, no beat sightings, and just a few human sightings! Otters I. The creek on descent, and an adrenaline pulsing hail storm literally from out of the blue (sky!). Trail not clearly marked at times.

Nice short trail that gives you views of the canyon and a small lake to relax at. There is also some geothermal activity along the trail that you can view up close. Not a must do trail in Yellowstone but certainly not disappointing.

Very short and easy. If you take the one-way drive you can stop at multiple points along the canyon rim and have amazing views at each one. I would recommend going down one of the trails that actually descends into the canyon some because that is where the best views are.

The waterfall itself is decent but I think Fairy Falls, which is near the Midway Geyser Basin, has a prettier hike and waterfall. As other people have said definitely do the overlook as that is the best part of the trail but also optional.

We hiked the clear lake trail to sublime point, then to artist point. Clear lake is a wonderful trail. I didn't know what to expect, but was wowed by it. The trail covers almost every geological feature that makes Yellowstone so special. The trail encompasses beautiful flowered meadows, scenic vistas, colorful lakes at clear lake and lily pad lake, and then hydrothermal features. The trail then leads to the south rim with incredible views of the canyon. This was a stunning hike. One major benefit is avoiding the parking lot at artist point since the trail starts from the wapiti lot. Be aware, though, since the south rim and uncle tom's trails are closed that the only way back to the parking lot is either back the way you came, or down the road.

We took the trail up to the Biscuit Basin Overlook first. I recommend this highly. That way the reward of swimming in Mystic Falls and being refreshed is that much more worth it. It's uphill to the overlook, but not too bad. Take lots of water and some snacks.

Be ready to take pictures. Saw lots of beautiful birds along the trail. It's a busy trail but not with all the bus traffic.

Unreal views of the Grand Canyon of the Yellowstone!
