E-Bikes Allowed

Family Friendly Juanita Cooke Trail and Laguna Lake are both very popular for kids and families.

No restrictions. Sections may be closed immediately after rainfall. Somewhere around 20 or so road crossings. Park at the Courthouse and head northward to go clockwise around the Loop.

Overview

A very easy 11+ mile loop right around downtown Fullerton with lots of variation. The loop flows clockwise and contains bridal trail and railroad-adjacent sections, true singletrack, a few steep and rutty climbs, lots of "extra credit", fast downhills, scenic vistas and even a shady lakeside section.

Need to Know

There are many junctions that are not marked specifically, so it helps to study the route via google earth before you hit it the first time. It is easy to miss some of the turns if you are unfamiliar with the route. Use the MTB Project mobile app to help follow the route. Elevation gain on this one is closer to 1015 feet rather than the listed 693 feet.

Description

Park at the Courthouse and hit the Bridal Trail, then head north to Hiltscher Park Trail, across Euclid past Sunny Hills HS along the tracks. From there, it's a long steady climb through Grisson Park to Tree Park.

Hop back on Rosecrans Ave for about a mile, then turn eastward over many climbs and drops on Horse Trail, across Gilbert and back to Euclid via the Nora Kuttner Trail.

Pass Laguna Lake with a scenic respite, then back to the bridal trail southward to the train tracks. Go over the small dam on the Brea Dam Trail and down along the golf course, under Bastanchury Road, through the wilderness and over Brea Dam, down to Harbor Blvd. and back to the Courthouse. Simple as that.

History & Background

The Juanita Cook trail was originally the route of the Pacific Electric Railway "Red Car" line to Fullerton. The western portions surmount West Coyote Hills.
