Castor River Conservation Area offers multiple access points via County Roads 820 and 822 for fishing at Fishing Lake and Grassy Creek, with parking areas and vault toilets available at designated locations.

The area features primitive camping at Trace Creek and Horse Camping areas, plus a shooting range, with multi-use trails for hiking and horseback riding throughout the 9,600+ acre property.

Note that direct access to the namesake Castor River is extremely limited, though several perennial streams provide riparian recreation opportunities.
