Bobcat Woods Boardwalk & Trail (Length: 1.5 miles)
This boardwalk and trail along Cocklebur Slough provide exciting wildlife watching opportunities. Under a woodland canopy, stroll on the boardwalk or sit and watch the wildlife come to you.

San Bernard Auto Tour (Length: 9.4 miles)
The auto tour, which includes the three-mile Moccasin Pond Loop, offers visitors an excellent opportunity to see wildlife in a diversity of habitats — from forested edge to fresh water ponds to salt marshes. Watch for bobcats trotting across the road, alligators sunning on the banks, and songbirds flitting in the trees. Moccasin Pond Loop provides an observation platform for waterfowl and wading birds.  *The auto tour is also a great place to enjoy wildlife while biking.
