Big Bend in April: what the park service says

April is the last month of Big Bend's main season, which the park service puts at October through April. Through April the Chisos Mountains Lodge and all developed campgrounds still fill every night, and any holiday weekend draws extra visitors, so book a campsite or room before you arrive rather than hoping for a spot. Campers who pull into a parking lot or roadside for the night get cited, so have a reservation or a plan outside the park.
