Driving a vehicle up the hill might get you to the cache much quicker and easier, but for the real geocaching experience... I challenge you to bring out your bicycle and pedal your way up the hill as far as you can. I will warn you though, be very cautious riding your way back down the hill as it does get quite fast and their may be an occasional bump in the road. The cache itself is well camouflaged so don't be surprised if you can't spot it at first glance.
Happy caching, and don't forget to wear your helmet!
Congratulations to flatenr for the FTF!
