This is an easy boardwalk that offers lovely views. However, to really enjoy the Grand Prismatic Spring I’d suggest taking the overlook trail.

Great views and a fairly short, very pretty hike. Kid-friendly. We were cautioned to watch for bears, as some frequent the area.

Very nice and easy hike. Amazing views. One is the few still open in October.

Such a pretty magical place. Absolute must if you go to Yellowstone.

Trail closed, bear activity. 9/26/18

A nice short walk.

This a a great hike with gorgeous views most of the way up. It took us about 1:15-30min to get to the top and that includes a few breaks for water and pictures (and about 45min to hike down). All 4 of us are decently experienced hikers and it was a bit strenuous at times, but not hard. Once at the top, there were some people up there and we decided to keep walking straight for about 5-10 more minutes to an area that had 4 stones to sit on and eat our lunch with 360 degrees of stunning views!

My wife and I did the loop yesterday. I used a website I found that shows the last time Old Faithful and the Grand erupted and an estimate for next eruption. We watched Old Faithful erupt twice; once from right beside it and once from the observation trail. The observation trail is much better vantage point. after that, we began walking the trail. I knew Grand was supposed to erupt sometime between 1 pm and 3 pm with my best estimate at 2 pm. We were approaching the Grand at 155 pm and it started to erupt!!!! I was like a little kid, partially because I lucked out on my estimate to be there and partially because the eruption was utterly amazing...much better than Old Faithful and longer. The crowd was amazed as well. The loop is a nice relaxing walk that just about anyone can do.

More geysers. All unique

Did this as a loop, going up the Bunsen Peak trail, east off the summit and down to the Osprey Falls trail. The Bunsen Peak trail is excellent. Well maintained with excellent views all the way up. View from the top is outstanding. It looses a star for the crowds, even after Labor Day, and the cell service at the top. This led to cell phones ringing and people texting or on their social media.
You leave everyone behind when you go east off the summit. The down side to that is that the trail isn’t in as good shape. There was a short stretch near the top crossing scree that required some path finding. After that the trail stays near the top of the ridge through mostly burned forest for a mile or so before going down steep switchbacks to a road. The views on the second part of the hike are not as good as on the way up but it’s nice to get away from crowds this close to one of Yellowstone’s major attractions.
Finally, even with my sea level lungs and arthritic knees I’d rate this hike moderate, not hard. There are many hikes rated moderate in AllTrails much harder than this one. Don’t be put off by the hard rating.

The geysers and pools are pure magic. Castle Geyser was definitely a favorite.

I personally enjoyed the beautiful pools of West Thumb even more than the Grand Prismatic area. It features beautiful views of Yellowstone Lake, and the pool depths and colors are other-worldly. The trail offers a brochure that talks about each feature that can either be returned or they ask for a dollar donation.

Go at sunset to get a great view of Grand Prismatic and alpenglow covered mountains. The new overlook trail is a steep but short hike.

Amazing view but very hard to enjoy with the crowd. Lots of rude foreigners with no consideration of others at all. Glad to see it from that vantage point once but will never do it again because of the crowd.

great view.

Don't be intimidated by the hard rating it is tough but very manageable and the views at the top are breathtaking.

A great hike. Well maintained and mostly clear trail. Easy to walk and maintain a good pace. Beautiful views all the way up. Hiked with my husband and 5 year old daughter.

nice walk along the lake. can be quiet windy but beautiful with the pools.

dragon's mouth spring was the neatest feature here. the mud pots at artists paint pots are cuter, lol.

being a scientist, of course i had to honor bunsen (burner, lol) peak! i found this hike refreshing after getting bogged down by the crowds on the boardwalk sights. although, it didn't feel like ~2 miles on the ascent. great views at the top.

Awesome view.

Good walk.

Nice walk. Beautiful views.

a short boardwalk stroll to very beautiful thermal pools
get there before it warms up to see the steam wafting through the air

So many mud pots. It's my first time to see the boiling mud. Very cute.

A interesting hike. Lots of mud pots. One of the advantage of this trail is that there will not be so many visitor as other places in Yellowstone. You can get peace here.

It's a great view to see the grand prism from this trail, and it's very easy.

The grand Grand Prismatic Spring is certainly one of the most deserve to see in the Yellowstone. However, It's too large to see the whole prism besides it. I suggest to hike both this trail and the other trail going to the mountain besides the prism and see it from above.
