The Mexican border and the Gulf of Mexico are two of the outstanding threads in the fabric of Brownsville, a Texas city that boasts natural beauty, historical attractions and a variety of traveler amenities. Birdwatching is enjoyed by thousands of avid naturalists in Brownsville each year, many of whom descend on the city during the Brownsville International Birding Festival in February. The Gladys Porter Zoo is another popular Brownsville attraction, as it is home to over 370 species of animals and 225 plant species. Children enjoy visiting the Children's Museum of Brownsville, which features several interactive and educational exhibits. Every year the city comes alive during the Charro Days Fiesta, a week-long February event that celebrates the local Hispanic culture. Those looking for fun in the sun flock to Brownsville's Boca Chica Beach or take the 27 mi (44 km) trek to South Padre Island.
