Free, informal spots with little or no infrastructure — the river bends, creek pools, and unmarked pull-offs that never appear on a tourism map.

These are the spots with no entry fee and little or no infrastructure: no lifeguard, often no restroom, sometimes no sign at the pull-off.

"Secret" is relative. Most of these are well known locally and busy on a hot Saturday — the difference is that nobody is managing them. Arrive early on weekends, park legally, and leave the place cleaner than you found it, because informal access is the first thing a landowner or county revokes.
