Follow the above advice plus pack extra mosquito killa in case of slack or North winds. You need a Matagorda County Beach Permit to ACCESS the beach and the access is across from the LCRA Nature Center. You can buy the permit at the only gas station/grocery in Matagorda, but I forget the name. Keep an eye out for news of beach/sand conditions, even 4x4s can get stuck, but even 2xs can maneuver fine: depends on conditions, vehicle and driver.
