This cache is a few miles up a dirt road that can be travelled by just about any car. There are a couple of rough spots so I recommend a vehicle with a little bit of clearance.
A sedan will get you to within .15 of the cache (750'). However, it will NOT get you to the cache. For that you'll need a 4WD and some brass ones because in the last 750' the road climbs 250'!!!!
Or of course you can be safe and there is room to park a short distance up the hill, and you can walk from there.
Have fun, Stay Strong, and Cache On!
