Passini Road connects to the Skyline Trail, the Buckeye Trail and Lake Marie Road for shorter loops.

Skyline Wilderness Park is an 850-acre wilderness area in the southeast
corner of Napa and is managed by a non-profit organization and is fee based to
assist with costs associated with the upkeep of the park.  The parks hosts tent and RV camping, archery
fields, Frisbee golf, the Martha Walker Native Plant Garden and a community
hall and picnic areas. There are over 17 miles of hiking trails open to hikers,
bikers and equestrians meandering through old growth oak woodlands, grassy
meadows and hillsides, to streams and canyons.
