Marathon is located in the remote Big Bend region of West Texas. Due to its remoteness, low population density, geographic location, being located in an ancient sea bed known as the Magnificent Marathon Basin, surrounded by mountains, at over 4000' and a community of only 430 full time residents, no wonder Marathon has been blessed with the darkest skies in the lower 48 states!

Big bend National Park was recently awarded the designation of Gold Tier Dark Sky Park as recognized by the International Dark-Sky Association.
