Padre Island National Seashore
One of the longest stretches of undeveloped seashore in the US, the southern part of Padre Island is administered by the National Park Service. Its main feature is 65 miles of white sand and shell beaches, backed by grassy dunes and the very salty Laguna Madre. The island is home to all the coastal wildlife found elsewhere along the coast and then some.
As small as Luckenbach is – there are only three permanent residents, not counting the cat – it's big on Texas charm. You won't find a more laid-back place. The main activity is sitting at a picnic table under an old oak tree with a cold bottle of Shiner Bock and listening to guitar pickers, who are often accompanied by roosters.
