The San Luis Rey River bike trail is a multi-use trail that follows the San Luis Rey River, whose headwaters are in the Palomar Mountain range some 60 miles inland. The path runs along the top of the flood-control levee built by the Army Corps of Engineers in the 1980s. Prior to paving the trail and it becoming the widely popular Class 1 bike route that it is today, it was used by the military as a private railway to move cargo along the river.
Starting in downtown Oceanside, along Neptune Way, the western terminus puts visitors a short distance from the Oceanside Transit Center, giving commuters easy access to points across the county and beyond. Additionally, visitors can connect with the planned 44-mile Coastal Rail Trail that will eventually link Oceanside to downtown San Diego.
The San Luis Rey River bike trail is a great opportunity to get outside for an extended bike ride, run, or just a brisk walk and see areas that are often hidden from the street. The west end of the trail begins at the beach and takes visitors along the river inland, offering up-close encounters with native plants, insects, and birds inhabiting the riparian zone. Common plant species include western sycamore, arroyo willow, cordgrass, and narrow-leaf cattail. Along with the native plants, this section is a great spot for bird watching, as many of the lagoons and rivers along Southern California’s coast are part of the Pacific Flyway. Birds commonly seen along the San Luis Rey include snowy egrets, blue herons, grebes, and various ducks.
The trail, designed with commuters in mind, is an easy-to-follow pathway; however, many sections do not have after-hours lighting and use after sunset is discouraged. As the trail takes visitors through various Oceanside neighborhoods, access to restrooms and water are available at stores and fast-food places off the trail. However, the two best spots along the trail to take a break with facilities are at the Alex Road Skate Park and Mance Buchanan Park.
Near Foussat Road and the Oceanside municipal airport is the Alex Road Skate Park. This park is open for skateboarding during daylight hours, 365 days per year, for skaters of all ages. Visitors can stop to watch the amazing skateboard antics, stop for water, or use the facilities. Be sure to keep an eye skyward when near the airport, as the area is a popular skydiving location.
Continuing east, the trail brings visitors to Mance Buchanan Park, with its soccer fields and running track, and finally to the edge of Guajome Regional Park and the current end of the trail. The adventure needn’t end there, as future plans call for extending the trail east all the way to Escondido.
Canyoneers are San Diego Natural History Museum volunteers trained to lead interpretive nature walks that teach appreciation for the great outdoors.
