El Paso is FULL of surprises, not the least of which being the home of the largest urban state park in Texas, the Franklin Mountains State Park! Hike rugged terrain in 37 square miles of desert wilderness, scrub vegetation and open space with 125 miles of multi-use trails that are especially popular with mountain bikers, hikers and mountain climbers. North Franklin Peak rises 3,000 feet above the city, and the park offers spectacular views from many locations. Here's a link to the park's website.
Preservation of the park's resources are a key issue. To read more, visit the website of the Franklin Mountains Wilderness Coalition and the elpasonaturally blog.
