About Sulphur Cave Spring
Sulphur Cave Spring in Colorado offers a rare and authentic experience with its warm, mineral-rich waters nestled within a cave. The spring's unique ecosystem, including a newly discovered species of worms, adds a sense of wonder to this sacred site revered in Native American legends. Its tranquil atmosphere invites quiet reflection away from typical tourist crowds.
Getting There
Reaching Sulphur Cave Spring requires a challenging 60-minute hike through rugged Routt County terrain. The trail demands a good fitness level and navigational focus, with limited parking at the trailhead. Prepare for a strenuous walk, as this primitive spring remains far from developed roads or facilities.
What to Expect
The spring water hovers around a mild 68°F, cooler than most hot springs in Colorado but inviting after the hike. The cave setting creates a serene, almost mystical environment with minimal visitors, allowing you to connect intimately with nature. Facilities are non-existent, reinforcing the raw and natural character of this swimming hole.
Tips for Visitors
Visit year-round but plan for changing weather and trail conditions. Bring sturdy hiking boots, ample water, and allow extra time for the return hike. Clothing is required in the spring, so pack swimwear you’re comfortable wearing in a primitive setting. No fees are clearly posted, so check local updates before heading out.
