Cosumnes River Preserve

Discover the wild heart of California’s Central Valley at the Cosumnes River Preserve, where nature and tranquility flow freely. Just a short drive from downtown Lodi, this 50,000-acre preserve offers a rare glimpse into one of the region’s last free-flowing rivers and its vibrant ecosystems.

Whether you’re an avid birder, a weekend hiker, or simply seeking a peaceful retreat among ancient oaks and seasonal wetlands, the Cosumnes River Preserve welcomes you with open skies and rich biodiversity. Stroll along scenic trails, paddle through serene sloughs, or bring your binoculars to spot sandhill cranes, herons, and over 250 bird species that make this preserve a birdwatcher’s paradise year-round.

This is more than a walk in the woods — it’s a chance to reconnect with the land, breathe in the fresh Delta air, and witness the rhythms of nature in a place that feels worlds away, yet so close to home.

Tip from the locals: Visit in the early morning or golden hour for the best wildlife sightings and unforgettable photo ops. Don’t forget your water and sturdy shoes!
