San Luis Rey Bike Trail

The San Luis Rey Bike Trail in Oceanside, California, is a dog-friendly trail that also accepts cyclists and walkers. Dogs must be kept on a leash that is no longer than 6 feet in length. The trail is largely flat and paved, with many entry sites, most of which are where the road meets the path. It's a well-kept trail, but it's not lit, so be visible at night.
