Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Pacific Flyway refuge at the south end of the Salton Sea where managed wetlands, fields, and desert uplands support huge seasonal concentrations of waterfowl, shorebirds, and rarities. The visitor center on West Sinclair Road anchors the Rock Hill Trail to a small volcanic cone with Sea overlooks; Unit 1 offers an observation tower and photo blinds. One of the West's premier desert birding destinations despite the Sea's environmental challenges.
