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.

Temporary Trail Closure at Reserve - Phase II

The trails to Hummingbird Island, over the Whistlestop Levee, and to the North Marsh Overlook will be closed due to construction between September 2 - 12.  A short bypass trail is being opened to enable visitors to complete the South Marsh Loop Trail.

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 will both improve the tidal range and circulation in the Whistlestop Lagoon, as well as stabilize the levee and reduce the trail's maintenance. It took several weeks to complete the initial work. This closure will allow us to finish up the work. Overall, this project will enhance the habitat at Whistlestop Lagoon and improve the public’s access to Hummingbird Island.

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