Continue the exploration of the Chihuahaun Desert by biking, hiking and canoeing through Big Bend National Park. Come along on a mountain bike ride on the back roads of the park and experience the beauty of an agave forest in bloom. Explore the park in search of signs of human occupation, from prehistoric fossils and cave paintings to European settlers and current-day explorers. Then canoe the Rio Bravo (called the Rio Grande by Americans) in one of the most isolated areas in Mexico. Hike and explore the flora and fauna found in canyons along the river.
