## About Pecho Warm Springs

Pecho Warm Springs is inside Montaña de Oro State Park near Los Osos, San Luis Obispo County. The water is a little below body temperature, soaking warm without being hot. Access is open under state park rules. Islay Creek Road leaves you a short walk away, a bit under a third of a mile, and Los Osos is three miles off.

State park ground, so the park's rules apply. Islay Creek Road is the approach. The elevation is modest, a few hundred feet, and the climate is mild year round with no snow and a moderate amount of winter rain. Nothing in the file describes the outlet or whether there is any kind of pool, so do not count on one.

The record leans toward winter, though with no snow and mild temperatures the spring is reachable year round. Access is open. Cerro Alto, about thirteen miles off and well outside the park, is the camping the record gives. No fee appears in the file; check whether the park charges for day use. The water is warm, well short of hot.
