 Some might say that without this tunnel Texas might not be the great state that it is. This tunnel is the result of man. We carved it out of the mountain so trains could haul goods to other parts of the state so everyone could prosper.

First stop on our trip to Canada. Old Tunnel State Park an hour away from San Marcos, Texas. The park is free and you can watch the bats fly out at dusk. #roadtripping #bats #tunnel #travel #BYADV #neatplaces #tpwd #oldtunnelstatepark

It was also the first railroad tunnel East of the Pecos River. It's 920 feet long and is still the only railroad tunnel in the hill country. Since it was abandoned in the 1940s it's now home to one or two bats. Which you're invited to come see at the Old Tunnel State Park.
