Eden Landing Ecological Reserve, Nature reserve in Hayward, United States

Eden Landing Ecological Reserve covers 5,040 acres of former industrial salt ponds on the eastern shore of San Francisco Bay, in Hayward and Union City. Managed by the California Department of Fish and Game, the ponds are now a low-salinity waterbird habitat, with restored marsh and the remains of the Oliver Salt Company inside the reserve.

The reserve covers 5,040 acres of former industrial salt ponds on San Francisco Bay's eastern shore, managed by the California Department of Fish and Game. It forms part of the South Bay Salt Pond Restoration Project, the largest salt pond restoration on the U.S. west coast. Over 1,000 acres of marsh had been restored by the time new trails and a kayak launch opened in April 2016. The remains of the Oliver Salt Company stand within the reserve.

The reserve lies within the South Bay Salt Pond Restoration Project, the largest salt pond restoration project on the west coast of the United States. The Bay Area organization Save the Bay plants native vegetation along the edges of the salt marshes. Some waterfowl hunting is periodically permitted, and new trails and a kayak launch opened to the public in April 2016.

Visitors can walk four miles of trails and observe wildlife from designated viewing points throughout the property. Kayak launching is available at Mount Eden Creek for those wanting to explore by water.

Concrete foundations and earthen dikes from the old salt works remain visible throughout the reserve. These remnants allow visitors to trace how the landscape shifted from industrial salt harvesting to restored natural habitat.
