Start your adventure at the Padre Island National Seashore, a 70-mile-long stretch of undeveloped beach. Spend the morning exploring the park's four distinct ecosystems: the Gulf of Mexico, the dunes, the grasslands, and the Laguna Madre. Take a dip in the ocean, go kayaking, or fish on the shore. In the afternoon, take a guided tour led by a park ranger to spot nesting sea turtles and migratory birds. Catch the breathtaking sunset before heading back to the city.
Drive to Mustang Island State Park, a barrier island with five miles of beachfront and sand dunes. Spend the morning hiking the park's nature trails or go birdwatching. Visit the Mustang Island State Park Fishing Pier and try your luck at catching some fish. After lunch, rent a bike and pedal your way on the beach or go for a horseback ride along the shore. End your day with a scenic sunset kayak tour through the island's bays and estuaries to experience the park's marine life.
