Mt Sepulcher is named for it's strangely shaped formations of volcanic rock near the summit. There are a number routes to take to get to the summit - this overview is based on a loop beginning at Glen Creek Trailhead (5 miles south of Mammoth - across from Bunsen Peak). The trail starts at Glen Creek Trailhead and follows Sportsman Lake Trail to the Sepulcher Mt trailhead. It then climbs 2300 ft through open meadows filled with wildflowers and sage bushes. Incredible vistas, alpine wildflowers, and possibly snow await at the summit. The loop continues on through a much more wooded trail and visits the sepulcher area - rock formations that resemble grave markers. Keep an eye out for mountain goats. The trail then heads down alternating meadows and woods, with a large area of fallen burned down trees. You have a choice of routes to return you to the Glen Creek Trailhead. Keep an eye out for elk and bears.

A good workout for roughly 7 hours. Great to escape from the busy trails. Great lookouts. Be sure you take enough water. We spotted two black bears.

This trail had an constant swarm of horseflies, got many bites, little blood spots all over my short now. On top of that, mosquitos were Abundant. Lots of energy beating the flies off and worrying about more bites. Took the trailhead listed on other websites near Glenn Creek. 12.5 mile round trip. Very physically challenging, make sure you bring enough water or a water filter and most importantly BUG SPRAY

Me and my friend did this trail today, and it pretty much dominated us. We are fairly athletic guys, and understand that being in shape and hiking shape are two different things. We went to the left at the start of the trail which is “backwards,” and it was pretty much 6 miles of straight incline. The last few miles up there are hardly any trees for shade, and it’s pretty tough uphill battle. It’s a great workout, and the views are decent, but if you’re not an avid hiker, the juice might not be worth the squeeze. It is rated as hard, and I believe that to be accurate. Coming down the other side was extremely steep at times, so I imagine that would be a pretty steep incline, but not as long.

Trailhead was hard to find- it is slightly north of the mammoth springs and behind a private residence. Beautiful hike with great views of Lamar Valley, Bunsen Peak, and into Paradise Valley. We unfortunately didn't get all the way up because of a grizzly mama with at least one cub were on the trail ahead of us close to the peak. We were very spooked- be sure to carry your bear spray. There was a note on the trailhead that another group saw a grizzly and cub in June 2019. I've been coming to Yellowstone for 20 years every year, and had never done this hike. It was great to see a new part of the hike. We will try to reach the peak again :)

Started at the trailhead adjacent to Mammoth parking area and went up, up, up. Beautiful but relentless. Elk bugling everywhere. Blizzard conditions as we approached ridge - a bit dicey with wind/snow whipping up ridge. No views. Once on SW side of ridge slope is less steep and more dry/high plains desert. Be prepared for changing conditions and consider taking route in reverse if steep inclines are not your thing. Great workout. Elk, mule deer, grouse.

Hike wasn’t too tough. A lot of the trees were burned down, but overall pretty scenic.

Really tough start, the ascent almost seems endless. Especially at the exposed ridge near the peak. But the view of Paradise Valley was very well worth it. Otherwise the hike brought you through many varied terrains and opportunities for wildlife. Trail was very well marked with a few minor detours due to remaining snow drifts.

Very beautiful view with very little traffic. While we were hiking up we crossed a black bear across a scream, we brought bear bells and spray as the chance of crossing a bear was fairly high. Trail can be difficult at times to navigate as it is not frequently sought out, bring lots of water and food!

Hard on the way up. Great trail all around. At the bottom, take the sign to mammoth 3 miles. My nat Geo map showed a .8 spur to meet up with Howard Eaton and cut a mile off. Don't do it! Had to get a ride back to mammoth!

Great, well-marked trail with little traffic. We left Mammoth at 1:00 pm and back in the car by 6:00 pm. Saw 8 elk, wild flowers and had great views. Saw no one else on trail after 1/2 mile. Cold at the top, bring a fleece and long pants.

This was a good trail but the marking could have been better. There are orange tags to follow. Saw some great wild flowers but little wild animals. Nice views at the top. Got an early start which was good as it was hit by Noon. Overall, a good day hike.

Nice trail through open meadows before you begin the ascent. Got turned around by an agitated moose and her calf I encountered on the trail shortly after I started up Sepulcher Mountain. Summit will have to wait until next year.

One of my favorite hikes of all time! Started out from the meadows across from Bunsen Peak. Beautiful meadows and then up into the mountain. A lot of snow at the top at that time, but gorgeous flowers and INCREDIBLE vistas at the top. Carrying on through the loop we were challenged by 8 foot snow drifts and disappearing trail.. But rewarded with mountain goat sitings, and close encounter with a relatively young grizzly, beautiful wildflowers and lots of climbing over deadfall. Somewhere we made a misstep with our trail choice and wound up on the Hoodoos trail, where we encountered a very very large mama grizzly with cubs.. Turned back and headed the last two miles back on the road.
