One of the largest protected natural areas in the Lower Rio Grande Valley, Laguna Atascosa National Wildlife Refuge is situated just a few minutes' drive away from the city. Extending over 97,000 acres, the park is a valuable resource that is essential to protecting local wildlife and plant species. Aside from spotting the endangered ocelot, there is plenty to see and do in the park and its coastal waters. Popular activities include fishing, hiking, and wildlife photography, as well as simply just admiring the stunning landscape from your Brownsville campervan rental. The refuge is also a bird spotter's paradise with more different bird species sightings recorded than in any other park in the National Wildlife Refuge System. Padre Island National Seashore makes up part of the refuge and is a definite must-visit in your Brownsville RV rental. It's an essential nesting ground for Kemp's Ridley turtles and one of the longest barrier islands in the world, protecting 70 miles of coastline. The park features two developed campgrounds and is a popular place to go canoeing and kayaking. You could also spend your time bicycling, beachcombing, or if you check your dates, you may even get to watch a sea turtle hatchling release. Another park located just minutes away in your Brownsville motorhome rental is Resaca De La Palma State Park and World Birding Center. Home to 1,200 acres of semi-tropical land, be sure to stop by the visitor's center and take advantage of the four decks that overlook the resaca, as well as taking the 2.76-mile tram tour loop. There are plenty of trails to explore either on foot or with one of the state park store's bicycle rentals. There are numerous park events throughout the year, including interpretative trails, visits to the butterfly garden, and craft displays. Spend the day exploring the 11 miles of park trails through sub-tropical wetland and woodlands, including Texas ebony and anacua trees, some of the most threatened tree species in the country. Several of the trails are also ADA-accessible, with plenty of useful information available at the park office. Take the short drive to Palo Alto Battlefield National Historic Site in your Brownsville camper rental. This must-visit park preserves the site of the Battle of Palo Alto, the first major battle of the U.S.-Mexican War. Much more than just a battlefield, the park also provides valuable insights into the causes and consequences of the war, as well as providing a peaceful haven for a variety of plant and wildlife species. The park extends over more than 3,400 acres of broad coastal prairie land, interrupted by resacas, or shallow ravines, that make for a marsh-like habitat during the rare heavy rains. If you're planning on visiting the park, it's a great idea to take a seasonal guided tour, so check out the program around your Brownsville RV rental reservation dates and really make the most of your visit. Also, check for any special events such as Living History programs and hallmark events during your vacation period.
