Hiking and camping attract lots of tourists every year especially during warm seasons. Travelers can always find some spots around the city, in the closest parks and natural areas. Outside San Antonio, in the northwestern Bexar County, there is a 12,000 acre Government Canyon State Natural area — beautiful destination for hiking and mountain biking. It's a great opportunity to see a variety of flora and fauna, explore more than 40 scenic trails and rest in a cozy cabin. One of the most special routes is a popular hike to see a hundred million years old dinosaur's footprint. The region is also full of beautiful rivers such as Medina, Blanco, Colorado, and San Macros, which offer their visitors kayak trips during the summer.
