Dogs in Cosumnes River Preserve

Can I bring my dog, and on which trails?
Limited access

This wildlife and wetland preserve does not allow pets. Only leashed service dogs are permitted, since loose dogs disturb the birds and other animals the preserve protects.

Pets are banned on all trails including the popular Cosumnes River Walk loop. Only service dogs on leash may join you. Leave other pets at home.

Where dogs are allowed

Where dogs are not allowed

All trails and grounds. Only leashed service dogs are allowed.

Seasonal closures

The preserve is a major stop for migratory birds, so fall and winter are the prime viewing seasons. Mountain lions, venomous snakes, and poison oak are present.

Leash rule

A 6-foot leash is required in developed recreation areas like campgrounds, trailheads, and picnic sites. On most of the open BLM land there is no leash law, but your dog must be under control at all times, and local field offices can set stricter rules.

Service animals

Service animals are allowed where pets are not, under the ADA. A leash is still required.
