About Fish Hatchery
Fish Hatchery is a serene, cold spring located along the Mad River in California. Its tranquil setting beneath towering cottonwoods offers a peaceful retreat, with the river doubling as a traditionally clothing-optional swimming area. The water runs cool and refreshing, though it can become shallow during the hottest summer days.
Getting There
Access to Fish Hatchery requires a short walk of 2 to 15 minutes from limited roadside parking. The spring lies in Blue Lake, west along Route 299 from Willow Creek or east of Arcata. After taking the Blue Lake exit, follow Chartin Road, turn right onto South Railroad Street, and continue to the road’s end before heading down to the river.
What to Expect
This spot is one of the more rustic hot springs in California, featuring a natural river swimming hole rather than a developed pool. You’ll find a quiet, reflective atmosphere with few visitors, ideal for soaking in nature’s calm. Facilities are minimal or nonexistent, so expect a primitive experience surrounded by wild beauty.
Tips for Visitors
Visit during summer when water levels allow easier swimming, but be aware the river may become shallow in the heat. Bring water shoes to navigate rocky riverbeds and prepare for limited parking. There is no entrance fee, and the clothing-optional policy respects personal choice, so dress accordingly.
