We started on this trail in Hayden Valley just after sunrise... the trail was foggy and wet but the sun soon burned through! We saw large herds of bison and ended up going off trail several times to avoid some that were in our path. Trail was flat and enjoyable and made for great pictures and wildlife sightings.

Just did 6 miles out and back from the trailhead north of alum creek. There are plenty of parking spots across the four pullouts south of the Mary Mountain trailhead. Saw a dozen bison less than a 1/4 mile from the trail, and had to walk between three bison around mile 2. We did the hike in late May and the trail was really muddy (I nearly lost a shoe in mud) high winds around 30 miles per hour. Beautiful scenery but not a lot of animals besides the bison.

We did about 5mi of this trail from the Hayden Valley trail head. The trail is fairly flat and can get muddy if there has been rain. You can see lots of birds, hawks, and buffalo. You also get some nice views of distant geyser basins.

We did this as a day hike (start early). The scenery was simple in a beautiful way. Lots of large open meadows and some rolling hills as well as many bison eating off in the distance. We took a quick dip at the lake because it was hot. Was definitely worth hiking!!!

Because of all the tourist and traffic we desiderata at the last minute to do the trail. What a great choice We only went in several miles but we did not see one other hiker. Trail follows a perfect beautiful stream We felt like we were in another time. Great wildlife. We stumble across some awesome geysers that gave us our own viewing show. There was evidence of recent landslides and we spent time studying that. There are dangerous areas on the trail. When you see the white calcified ground be carful where you step. The ground is hollow and boiling water lurks just below so don't fall in you will die.

This was a most peaceful hike we loved it

Very confusing trail because of the bison that have trampled the trail and caused us to take one of their paths instead of the actual trail. Besides that a very moderate very scenic hike through Hayden Valley. Be careful of backcountry mud pots!!!
