Mercey Hot Springs is a historic geothermal spa nestled in California's Little Panoche Valley near Firebaugh across 144 acres. The resort offers diverse accommodation—nine cabins, tent camping, RV sites, Airstreams, and a Walkabout house—all with access to mineral-rich thermal pools heated naturally to 102-106°F, plus private soaking tubs, outdoor grills, and a disc golf course. Entirely solar-powered with no cell coverage, the property emphasizes ecological sustainability and offers guests stargazing, birding, and hiking in a quiet, technology-free setting. Nearby attractions include San Luis Reservoir, Pinnacles National Park, and historic towns of Gilroy and Hollister, though Los Banos (35 miles) provides essential supplies. (via official site)
