South Laguna Summit-to-Sea Professional Review and Guide
"Although most of this ride is busy with motor vehicles, there are bike lanes along nearly the entire route. Thus, bicycles and motor vehicles can coexist— well, not always in harmony—through some of southern Orange County’s most favored scenery.
The ride is hillier than Ride 21, Laguna Beach Pageant of the Pedals, which is this ride’s companion, making this the more challenging option. The climbs are strenuous, but the descents are rewarding, and there are some great ocean views. The recommended direction for this ride is clockwise, to take advantage of right turns."
