U.S. District Court Judge Terry Hatter Jr. sided with four hikers who
contended that Southern California forests were improperly requiring them to
buy an Adventure Pass even when they didn’t use any developed facilities.

Although the Angeles, Cleveland, Los Padres and San Bernardino forests
reduced the number of fee areas, they continued to require a pass at certain
busy sites equipped with amenities such as toilets, interpretive signs and
picnic tables -- even if hikers were only parking and not using the
facilities.

That, Hatter said in Monday's opinion, violated the law.

“What they can’t do is just assume that anyone who is parked at a trailhead
is using the facilities,” he said.
