Desert Reef Hot Spring

## Overview Desert Reef Hot Spring is a rustic, naturally heated geothermal spring located in the arid landscape of Fremont County, Colorado, at an elevation of roughly 6,000 feet along the eastern edge of the Sangre de Cristo mountain range. Situated at GPS coordinates 38.3684787501195, -105.049213957866, this remote hot spring lies in the high desert terrain south of Cañon City, offering visitors a unique soaking experience surrounded by sweeping views of the Arkansas River valley and distant peaks. Desert Reef is well known among Colorado hot spring enthusiasts as one of the few clothing-optional, primitive soaking spots in the region. The spring feeds into a series of shallow, hand-dug soaking pools that have been maintained over the years by regular visitors. Water temperatures at the source have been reported to range from approximately 100°F to 115°F (38°C–46°C), though temperatures in the soaking pools can vary depending on weather conditions, wind, and how recently the pools have been maintained. The area sits within the Rio Grande Rift zone, a geologically active region where the Earth's crust is slowly pulling apart, allowing geothermally heated groundwater to rise to the surface. This same geological activity is responsible for many of the hot springs found throughout central and southern Colorado. Desert Reef has historically been used as an informal, free soaking destination on public land, though visitors should be aware that access conditions and land management policies can change. The spring has a loyal following among locals and travelers who appreciate its off-the-beaten-path character and the stark beauty of the surrounding desert landscape. ## Directions 1. From **Cañon City, Colorado**, head south on **US-50** and then turn south onto **CO-115 South** (also known as Penrose Boulevard). 2. Continue south on CO-115 for approximately 10–12 miles. 3. Turn right (west) onto **Fremont County Road 11** (also referred to as Copper Gulch Road). 4. Follow CR-11 west for several miles into the desert terrain. The road is unpaved and can be rough — a high-clearance vehicle is recommended, especially after rain. 5. Watch for a turnoff or informal parking area on the south side of the road. The spring is located a short walk from the road in a low-lying area. 6. GPS coordinates **38.3684787501195, -105.049213957866** can be entered into a navigation app to help pinpoint the location, though cell service may be limited in this area. *Note: These directions are approximate and based on commonly reported routes. Road conditions and access points may vary seasonally. It is advisable to check current conditions before visiting.* ## What to Expect Desert Reef Hot Spring is a primitive, undeveloped soaking site — there are no facilities, restrooms, changing rooms, or services of any kind. Visitors should come prepared with their own water, sun protection, and anything else they may need. The soaking pools are shallow, hand-dug depressions that collect the naturally heated geothermal water. Pool conditions depend heavily on recent visitor maintenance and weather. During windy days, the open desert setting can make soaking cooler than expected, while calm, clear nights offer a spectacular stargazing experience from the warm water. The landscape is stark, open high desert with minimal shade. Summer temperatures can be intense, so early morning or evening visits are popular. In winter, the contrast between the hot water and cold desert air creates a memorable experience, though access roads may be more challenging. Desert Reef is traditionally a clothing-optional location, and visitors should be prepared for that possibility. The site tends to attract a respectful, leave-no-trace crowd. As with any primitive hot spring, visitors are encouraged to pack out all trash and leave the area as they found it. The water has been historically used for recreational soaking and is not treated or tested — it should not be assumed to be safe for drinking.
