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.

Really tough start. Totally worth the varied climates and terrains.

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.
