Final Thoughts on Rainbow Hot Springs
Rainbow Hot Spring rewards hikers willing to cover 10 to 12 miles round-trip for a free, undeveloped soak in a genuine wilderness setting. It suits experienced hikers, backpackers, and anyone comfortable with river crossings and primitive conditions.
It is not a good fit for visitors seeking an easy, short walk or a developed facility with amenities. One detail worth remembering: trail distance estimates vary by source, so budgeting extra daylight is safer than trusting a single mileage figure. Plan the hike with proper gear, and the reward is a quiet soak deep in the San Juan Mountains.
