Day Hikes While You Are Here
From Lajitas and Terlingua, there are some great trails you can get to in a few minutes, and hike for an hour or two, or make a day of it.  See our new day hike page.

On Saturday before, and Monday after the race, a guided hike by Ranger Amber Harrison will leave at 10 am from the Contrabando Trailhead for a 6 mile round trip hike. An easy hike to loosen up, it will be on the Fresno Divide Trail. Last year was a great success, so Saturday before has been added.  We need a minimum number of participants, so sign up in advance.   See our new day hike page.

A Great Event !!!

The Big Bend Ranch State Park is a fantastic place to run, and the Big Bend 50 owes it all to the volunteers, park rangers, EMS teams, ham radio operators, hotels, campgrounds, timing team, sponsors, and our great runners for making it happen, keeping everyone safe, and having fun.
