Although Sonoma County's inland parks are open, as a coastal preserve Jenner Headlands remains closed as are all other coastal state and regional parks.

The managers and rangers that live on-site will continue to care for and keep secure this magnificent landscape we’ve all come to know and love.

The situation with the pandemic changes daily. We are looking forward to a time in the near future where we can meet on the trail once again. Until then, be well and stay safe.

Please continue to visit this webpage or the Jenner Headlands Preserve on Facebook for future updates.


March 13, 2020 | The preserve is experiencing increased daytime Mountain Lion activiting on our trail system. Please hike with caution. Always keep your dog on a leash when visiting Jenner Headlands.

Mountain lions are usually calm, quiet, and elusive. When hiking in lion territory, it is recommended you hike in groups and keep your children close by. If you see a lion on the preserve, please do the following:

  • Stay calm. Hold your ground, face the lion, and stand upright. Never turn your back to the lion.
  • Do not approach a lion. Give them space to escape.
  • Do not run from a lion. This may stimulate the lion's instinct to chase. Instead of running, make loud noises and wave your arms.
  • Do not crouch down or bend over.

Jenner Headlands is a spectacular 5,630-acre mosaic of redwood and Douglas fir forests, oak woodland, chaparral, and coastal prairie overlooking the Pacific Ocean. The property adjoins Pacific Coast Highway for two and one-half miles adjacent to Sonoma Coast State Park just north of the Russian River Estuary. Many rare and endangered species inhabit the property including the northern spotted owl, peregrine falcon, and red tree vole. Deer, bobcat, coyote, mountain lion and steelhead trout are also found on the property.

This 2009 acquisition was a result of the dedicated four-year effort by the Sonoma Land Trust and the Sonoma County Agricultural Preservation and Open Space District. Five other funding sources: the California Coastal Conservancy, the California Wildlife Conservation Board, the National Oceanic and Atmospheric Administration, the Gordon and Betty Moore Foundation, and Forest Legacy Program. The Wildlands Conservancy loaned and guaranteed loans totaling $10.6 million to insure this acquisition when funding was threatened. It is the single largest conservation land acquisition in Sonoma County history.

In September 2013, Sonoma Land Trust transferred the fee title of the property to The Wildlands Conservancy to manage as a preserve governed by consensus management decisions between TWC and Sonoma Land Trust.

At the time of its purchase, Jenner Headlands was the single largest conservation acquisition in Sonoma County history.


Sonoma Land Trust and The Wildlands Conservancy worked closely in developing a resource management plan to restore the coastal prairie and to aid the recovery of old growth redwood forests from decades of logging. Restoration of logging roads and restoring clear running streams will aid the recovery of the endangered Coho salmon.
