Napa Lapa
The Napa Lapa Trail Adventure is Inside Trail’s first time-based run. This means that instead of running a pre-determined distance as fast as possible, you’ll be running for a pre-determined amount of time as far as possible. And what other place could be better than the beautiful, rolling hills of Napa’s Skyline Wilderness Park?
Skyline Wilderness Park is located in Napa, California. In 1979, the land beside the State Hospital was declared to be surplus and was to be sold to a private party. A group of concerned citizens got together and enlisted the help of various members of the community and government to allow the group to use the land as a park for the Napa Valley. The idea of a park was formed, a constitution was created, incorporation papers drafted, environmental impact studies made, etc. Since there has never been a private sector leasing state land for a park system, the State leased the land to the County of Napa which then subleased it to the Skyline Park Citizens Association. More on the history of Skyline Wilderness Park here.
Skyline park has 25 miles of multi-use fire road and singletrack trails of various skill levels. As a memorial to Martha Walker, the Martha Walker Native Habitat Garden in Skyline Park was created, inviting visitors to enjoy a unique presentation of flora from all over the State.
