Fishing licenses are also sold. Fishing and boating are what draw people to Calaveras. There are two access points for boats, and fishermen use the cleaning and weight stations.
Fishing here is excellent for red drum, hybrid striped bass and channel catfish.
Largemouth bass are also caught, but in smaller numbers. There is easy shoreline access. There is no established trail system at Calaveras, but adventurous types will have plenty of shoreline to explore. Camping facilities are primitive. Motorhomes are allowed in the park, but there are no hookups.
