Sweet Springs Nature Preserve

Welcome to the Sweet Springs Nature Preserve!

The Sweet Springs Nature Preserve is located on Ramona Avenue in the town of Los Osos and has been managed by the Morro Coast Audubon Society since 1988. The preserve offers hiking trails, excellent birding opportunities, and excellent views of Morro Bay and Morro Rock. Sweet Springs is a 24+ acre preserve with a trail system over 1 mile long. There is no beach access.

For the protection of wildlife and bird species that inhabit and nest in Sweet Springs, dogs and other pets are not encouraged, but are currently allowed. Pets must be kept on a 6-foot leash and stay on trail.

History of the Sweet Springs Site - from ~500 AD to 2017
Archeological artifacts indicate the area where Sweet Springs is located was originally settled by the Chumash as early as 500 AD and they lived there through the late 1700s. The area was subsequently “discovered” by the Spaniard Captain Gaspar de Portola during the ‘Sacred Expedition,’ from Mexico through San Diego to Upper California, from 1769 to 1770.

East Sweet Springs Expansion Project
The Morro Coast Audubon Society acquired the 8.3 acre East parcel in 2008. In 2011 MCAS  applied to the County of San Luis Obispo for a minor use permit (MUP) allowing for native plant restoration and public access project at East Sweet Springs. In 2017 the MUP was approved and now East Sweet Springs will be developed with boardwalks, signage, benches, viewing blind, and more. Together with West Sweet Springs and Central Sweet Springs,  the Sweet Springs Nature Preserve will continue to be a place to walk, watch birds, and enjoy a quiet and peaceful natural environment.
