Conundrum Hot Springs Guide

Soak in a Wild Hot Spring at the End of a 17-Mile Round Trip · Aspen
A Kick-It Pick
Worth the drive
natural hot pools 8.5 miles into the wilderness under a wall of fourteeners, permit-only and earned on foot. Soak where you had to hike to get there.

There’s no road to Conundrum. The clothing-optional soaking pools sit at roughly 11,200 feet in the Maroon Bells–Snowmass Wilderness, and the only way in is the Conundrum Creek Trail #1981 — 8.5 miles each way, a 17-mile round trip that gains thousands of feet and stays snowbound into June. The reward is a string of hand-built rock pools of natural hot water perched on a bench with fourteeners standing over you and, after dark, a sky with nothing between it and you. This is a backpacking trip, not a soak-and-drive: you sleep up there, at one of exactly 20 designated campsites, and you carry everything back out. The altitude and the mileage are the filter — plenty of people underestimate both.

The move: Every overnight requires a permit through Recreation.gov, and there is no walking it back — the 20 sites sell out in minutes. Reservations open 8 a.m. Mountain time on February 15 (for April–July nights) and June 15 (for August–November); set an alarm and book the second they release. Go July through September once the snow's off the trail, filter your water, and store food in the required bear canister. Don't be the one who treats a 17-mile alpine round trip like an afternoon dip and runs out of daylight above treeline.
