What Should You Know Before Going to Sand Dunes Pool
Sand Dunes Recreation is a commercial hot springs facility, which means it comes with amenities not found at primitive sites—like showers, restrooms, changing rooms, a snack bar, and onsite lodging. The main pool is family-friendly and kept at a comfortable 98°F to 100°F, while the therapy pool and Greenhouse Lounge tubs are warmer, up to 106°F.
The resort operates on a daily schedule, but is closed every Thursday for weekly cleaning. Admission is paid at the entrance, with discounts available for children, seniors, and military, and an additional charge for access to the adults-only Greenhouse Lounge (ages 21+).
The Greenhouse Lounge includes a bar, music, and multiple hot soaking tubs in a leafy, tropical-like setting. It’s quieter than the main pool and perfect for relaxing with a drink after sunset. Note that no outside food or alcohol is allowed, but the facility offers a café and bar.
The resort is especially popular in summer and on weekends, so arriving early or visiting on a weekday is recommended for a more relaxed experience. Towels are available for rent, and both day visitors and overnight guests are welcome.
How to Get to Sand Dunes Pool
Sand Dunes Recreation is located in the town of Hooper, Colorado, about 30 minutes north of Alamosa and 40 minutes southwest of Great Sand Dunes National Park. From Alamosa, take Highway 17 north, then turn right onto County Road B just before reaching Hooper. The entrance is clearly marked with a large sign, and the turn is easy to miss—so drive slowly and keep an eye out.
The resort has a gravel driveway that leads directly to a spacious parking lot in front of the main entrance. Parking is free and available for both day-use visitors and overnight guests. RVs and campers can also park here if they have a reservation.
There’s no public transportation to the facility, so a private car is essential. The roads are generally well-maintained and accessible year-round, but in winter, check local conditions for snow or ice.
Once inside, you’ll check in at the main entrance building, where staff can provide pool access, towel rental, and information about the Greenhouse Lounge or camping.
Best Time to Visit Sand Dunes Pool
Sand Dunes Recreation is open year-round, but the best time to visit depends on what kind of experience you’re after. The most popular months are spring (April–June) and fall (September–October), when temperatures are mild and the outdoor soaking areas are most comfortable. These seasons are also ideal for combining a soak with a visit to Great Sand Dunes National Park, located about 40 minutes away.
Summer (July–August) brings longer hours and warm evenings, but also larger crowds—especially on weekends and during school holidays. The facility remains open late, making evening visits a great option to avoid the heat and enjoy sunset soaks.
Winter offers a quieter atmosphere and steamy soaking under snowy skies, but note that reduced hours apply (1:00 PM to 8:00 PM), and some nights can be quite cold after sunset. If you’re visiting during winter, check road conditions and dress accordingly for the walk between your vehicle and the pools.
No matter the season, weekdays and early mornings tend to be less crowded, especially if you’re looking for a more relaxed and peaceful visit.
