Apart of Mission Trails Regional Park in San Diego, CA, Kwaay Peak's main established trail offers an easy access 2.5 mile out and back hike great for any short day hike.
Exiting 8 East from the city of San Diego, drive east on Mission Gorge Road, turn left (west) onto Father Juniper Serra Trail and drive 0.4 miles to the first large vehicle gate. There is ample parking available on the "Old Mission Dam" parking lot. You will see the sign for the Kwaay Paay Peak trail across the street (south) from the parking lot.
Father Junipero Serra Trail has two entrances, enter the park from the most eastern entrance from Mission Gorge Road.
I would highly suggest Jerry Schad's book "Afoot & Afield, San Diego County", Wilderness Press. Very throughout research into all the hikes in and around the San Diego region.
