Padre Island
This is a trip down to the Padre Island National Seashore. This area is a 60 mile stretch of beach along North Padre Island. North Padre is not to be confused with South Padre of spring break fame. This is a four hour drive. Camping is required as is plenty of gasoline. You will have to drive almost 200 miles without refueling to make it back from the end of the island.
