Monserate Mountain Preserve is a nearby trail we checked out recently. A short but steep trail just off Interstate 15 in Fallbrook, CA. I will warn you the trail is rocky and a bit unleveled. I think each of us had our fair shares of stumbles. I wouldn't advise this trail for any children under age 8. On a positive note, the trail is heavily populated and has a great mountaintop view.
Wild Sage growing along the trail.
Wild Rosemary growing along the trail.
I'm loving this trail for a heart healthy and nearby hike.
But not loving it enough to visit again.
