You can park at the start of the dirt road and hike up the 1.7 km to the top, then its only a short distance to the cache. Otherwise you may choose to drive all the way up to the top. Most vehicles should be able to make it but you may prefer to have a 4x4 as you get close to the top. The view from up here is quite impressive. Its only a short hike from the tower to the cache location.
The cache is a small PB jar hidden on top of the mountain.
