Ownership is listed as other state land under a conservation designation, which in practice means park rules. Upper Arcadia, about ten miles away, is the nearest campground on file.

The record gives no best months, though the climate figures point to winter and the shoulder seasons over summer. Roadside. Park hours and any entry fee are not on record for this spring, so check before you go.

75 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 10% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
