Pinnacles in May: what the park service says
May at Pinnacles shifts its wildflowers toward plants that like hotter, drier weather, the park says: chamise, buckwheat, clarkias, penstemons and roses. Plan around the caves: from mid-May to mid-July all of Bear Gulch Cave closes while the Townsend's big-eared bats raise their young, the largest maternity colony between San Francisco and Mexico. The dry season starts in early May. Dehydration is one of the most common emergencies rangers respond to here, so carry plenty of water on the exposed trails.
