Ther is a great trail about 1 mile up of switchbacks. People actually mountainbike up it. At the top is a beautiful meadow and the resevoir that was created when they built a dam several years ago.
Its fabulous and only about 15 to 20 minutes away from where you live.
Chris,
I believe ocean views might be possible in the Elfin Forest and great surfing is only 15 to 20 minutes away if thats important.
