The Aliso Creek Trail goes from South Laguna to Rancho Santa Margarita. It is an 18.5-mile multi use trail corridor that goes through a number of parks on the way. There are plenty of rest areas on the way for you. Starting shoreside, the trail goes gradually uphill, but it will be a fun trip on the way back.

Mission San Juan Capistrano was founded more than two hundred years ago, in 1776. It was the 7th of 21 missions in California. This mission is one of the few that only allows visitors with a purchased tour, but riding by bikers can get a view of the old structures.
