Great Sand Dunes in April: what the park service says
April is when Great Sand Dunes' camping season starts: Piñon Flats Campground is open from April through October, and vehicle camping in the park becomes possible again after the November-to-March ban. The visitor center keeps its year-round hours, 9 a.m. to 4:30 p.m. The Medano Pass Primitive Road opens for driving and camping in late spring, depending on conditions, and needs a high-clearance 4WD vehicle. It is still too cold for most insects, though a few no-see-ums, tiny biting gnats, may appear on warm afternoons.
