Warm Mineral Springs (Big Salt Spr)
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Warm Mineral Springs, also recorded as Big Salt Spring, is a water-filled sinkhole in North Port, Sarasota County. The town of Warm Mineral Springs is about a mile away. Water on file is warm, somewhat under body temperature. It sits roadside, two hundred and fifty feet or so from Ortiz Boulevard.
Low and flat, ten feet above sea level, with no snow on record and a wet climate by inches of rain. Wikipedia puts the sinkhole a mile north of U.S. 41. Getting to the edge involves almost no walking from the road. Ownership and fee are blank in the record, so the practical side of a visit is not documented here.
Climate scoring favors the winter months. No campground appears. The water is warm, under body temperature, so there is no heat risk. Check current access before you go; nothing here says who runs the site or what it costs to get in.
Wikipedia describes the spring as a sinkhole whose main water supply is a vent deep beneath the pool's surface, and names it the only warm water mineral spring in Florida. The record also carries the name Big Salt Spring.

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.
