About this place

Conundrum Hot Springs sits at 11,200 feet in the Maroon Bells-Snowmass Wilderness near Aspen, Colorado — one of the highest-elevation natural hot springs accessible by trail in the state. This is public land managed by the White River National Forest, not a developed naturist resort. You'll earn your soak: the trailhead starts near Aspen, and it's roughly 8.5 miles one-way with significant elevation gain through aspen groves, conifer forest, and alpine meadow. The payoff is two small soaking pools fed by mineral water that hovers around 100°F, set in a stunning high-country basin with views of jagged peaks. Clothing-optional use is a decades-old tradition here, though the Forest Service doesn't officially designate it as such. You'll find a mix — some visitors strip down, others don't. Weekends in summer (especially July through September) see heavy traffic, and the pools are small enough that 6–8 people fill them comfortably. Crowding is common. This is wilderness. No bathrooms, no trash service, no cell signal. You pack in everything and pack it all out. Camping near the springs requires a permit from the Forest Service, and those fill up fast during peak season. Conundrum isn't part of the organized naturist network — no AANR affiliation, no resort amenities. It's a backcountry pilgrimage for people who want natural hot water, alpine solitude, and the option to be nude in a spectacular setting.

Who visits

You'll see a broad cross-section: serious backpackers, day hikers willing to push hard, Colorado locals, and out-of-state visitors drawn by Aspen's proximity. Weekends skew younger and more social; weekdays attract solitude-seekers. Families occasionally, though the distance and elevation filter out casual visitors. The clothing-optional tradition attracts naturists, but textile visitors are equally common. Expect a respectful, low-key vibe — most people are too tired from the hike to be anything but mellow.

How to find it

The trailhead is near Aspen off Castle Creek Road, about 10 miles south of town. Park at the Conundrum Creek Trailhead — popular and often full by mid-morning in summer. The trail follows Conundrum Creek valley, crossing the stream multiple times (log bridges, but expect wet feet). It's well-marked and heavily trafficked. The final stretch climbs steeply into the alpine basin. High-clearance vehicles help on the last miles of access road, but most passenger cars manage.

Things to watch out for

This is serious high-altitude backcountry. Weather changes fast — afternoon thunderstorms are common in summer, and snow can hit any month. Overnight camping requires a free permit from the Forest Service, available online and at the Aspen Ranger District, but they're limited and book out weeks in advance during peak season. Bears are active — bring a bear canister or use the provided food storage. Altitude sickness is real at 11,200 feet. Water from the springs isn't potable; treat or filter creek water.

Etiquette & ground rules

Respect both clothed and nude visitors — it's not exclusively naturist. Keep voices down, especially if camping overnight. Don't use soap or shampoo in the pools. Pack out everything, including toilet paper. The Forest Service has installed composting toilets near the camping area — use them. Photography is common but ask before including people in shots. Give arriving hikers space to decide their comfort level before claiming the pools.

Boulder Reservoir

Boulder Reservoir is a City of Boulder managed recreational lake with one of the few formally designated clothing-optional beach sections in Colorado — Beach 3, at the eastern end of the reservoir, where nudity is officially permitted by municipal policy. The C/O designation has been in place for decades and is a point of local pride in a city that has long maintained a progressive approach to outdoor recreation and body freedom. The reservoir's beaches are flat, sandy, and sunny, with the Front Range as a backdrop to the west and the Boulder Flatirons visible on clear days. The water warms to comfortable swimming temperature by mid-July and stays swimmable through September. Beach 3 tends to draw an older, relaxed crowd of regular locals and university-connected visitors who treat it as their neighborhood swim spot. The city charges a day-use fee for reservoir access. Parking is available, and the beach is reachable without a long hike — making this one of the most accessible designated C/O freshwater beaches in the Mountain West. Sailboats, kayaks, and stand-up paddleboards share the water with swimmers.

Dream Canyon

Dream Canyon is a popular climbing and swimming destination in Boulder County, west of Boulder along the North Boulder Creek drainage, near the town of Nederland. The canyon is named for its dramatic granite formations — the same rock that draws technical climbers to its walls — and the creek below offers cold, clear pools that have attracted informal clothing-optional visitors for as long as Boulder residents have been coming to the area. The C/O tradition is strongest at the more secluded pools upstream from the main access area, where the combination of canyon shade, cool mountain water, and the working assumption that clothing-optional behavior is normal in these contexts has persisted through multiple generations of Boulder outdoor culture. It's not a posted C/O area, but the regulars treat it as one. Summer is the primary season — the creek runs cold from snowmelt through July, then warms slightly through August and September. The canyon sits at roughly 6,500 feet, which keeps temperatures pleasant even in peak summer. Fall colors in the aspens above the canyon make September and October visits particularly scenic.

Dakota Hot Springs

Dakota Hot Springs is a natural geothermal facility about 5 miles north of Desert Reef Hot Spring in the Arkansas River valley of Fremont County, Colorado. The spring feeds pools at approximately 102°F in an open high-desert setting with mountain views. Like its southern neighbor Desert Reef, Dakota operates as a clothing-optional facility — the two springs together make this part of the Arkansas River valley a destination for Colorado naturists who want a dedicated C/O soaking experience without driving to the mountains. The facility is smaller and simpler than Strawberry Park — it's a local, community-oriented operation rather than a tourism product. This means fewer amenities but a more regular-crowd, relaxed atmosphere. The surrounding Wet Mountain Valley and Fremont County terrain is dry, open, and distinctly Colorado Plateau in character — different from the alpine hot spring experience in the mountains. Both Dakota and Desert Reef are accessible from US 50 east of Canon City, making them practical stops on a drive through central Colorado.
