Elkhorn Slough National Estuarine Research Reserve Trails

The Elkhorn Slough National Estuarine Research Reserve is home to 5 miles of hiking trails that meander through a variety of habitats. The colored lines on the map mark the trails.

The trails to Hummingbird Island, over the Whistlestop Levee, and to the North Marsh Overlook are now open!

The trails were closed earlier this summer in order for us to remove three impaired culverts (pipes that carry water) under the trail at Whistlestop. We replaced them with a 15' long box culvert opening which doubles as a bridge (pictured right).  This change improves the tidal range and circulation in the Whistlestop Lagoon, as well as stabilizes the levee and reduce the trail's maintenance.

Overall, this project will enhance the habitat at Whistlestop Lagoon and improve the public’s access to Hummingbird Island for years to come!

Project funding was provided by the American Recovery and Reinvestment Act and the California State Coastal Conservancy.
