Sonny Bono Salton Sea National Wildlife Refuge

The Michael Hardenberger Trail is located at Unit 1 off Vendel Road, which is at the south end of the Salton Sea. The .9 mile loop encircles one of our freshwater duck ponds with access to a photo blind. The trail includes both an observation deck and observation tower, which overlook the refuge’s marsh habitat and farmed winter foraging fields. This trail is best used during the winter months when the ponds are filled for migrating and overwintering birds.

The Rock Hill Trail is approximately 2 miles roundtrip, leading visitors through several different habitats. It begins next to the picnic area at the Visitor Center and ends on the top of Rock Hill, which is located on the edge of the Salton Sea.
