If mountain biking is your thing then absolutely bring your bike for this cache! Tompson Street Reservation has some of the best riding this area has to offer, from man made objects to crazy ledge formations it has it all. A bike is not needed though, the hike in is not terribly difficult and has some great views of the ocean if you get to the top of the right ledges. The cache is an ammo container just steps off the trail in an area with most of the man made objects for MTB. Be careful and enjoy this incredible place
