625 E Hopkins St, San Marcos, TX 78666, USA
That is the address for the San Marcos Public LIbrary. The park is sorta behind it, just pull into the library and go to the back of the parking lot...You can't miss it.
If you have any other problems finding it....Check in with www.bonelessone.com
, and find the San Marcos Skatepark thread on the message board.
