Being Martha flowers and ask her.
Thank you so much!AFAIK there is no pass required for Martha's Grove, or for any part of Sycamore Canyon / Goodan Ranch north of the where the Ridge Trail (coming down from the top of Cardiac / Sycamore Park Dr. parking) hits the bottom of the canyon near the Goodan Ranch south gate.
Now if you want to ride the canyon south of there down to Santee, on the Stowe Trail, that's MCAS Miramar property and you need a pass from the Marines. This requires some forms to fill out and a bit of time spent at the base & decal office on base, east gate off Miramar Way. Last time I was there, I was in & out in 15 minutes.
I'll come back later and post the links to the forms. Funny enough, I was planning to go renew my pass tomorrow.
You are thinking of the Stowe Trail at the southern border of the area. Details here: Stowe Trail Alignment - San Diego Mountain Biking AssociationCan someone explain how to get a pass for Martha's Grove?
Thanks!
