5.5mi Meritage Loop

Rate this Adventure San Francisco Skyline Wilderness Park

Added by BayTrailrunners

  • Distance: 5.5 miles
  • Total elevation gain: 1167 ft
  • Single track, fire road, hills

Skyline Park is the perfect playground for the committed trail runner. The park has fast and swoopy forest singletrack, semi-technical climbing, and everything in-between. The miles and the elevation gain here make the runs in the park somewhat demanding, but you can start with smaller distances and bail out on the fire road if you run out of steam on the singletrack.

To access these trails you can park in the official Skyline Parking lot off of Imola Ave, or, if you prefer, you can park in the picnic area across from Napa Valley College on Streblow Road. Run East across Napa Valley Highway heading into the forest on the River-to-Ridge trail. Run 1.5 miles over swoopy sandstone until you reach the Lake Marie Road. Take Buckeye trail up the ridge, then continue straight through multiple trail junctions until you reach the Skyline Trail. Turn left and run past Lake Marie, heading deeper into the hills. The trail now makes a simple lasso loop-- simply stay on it and it will loop you around after 2.5 miles and return you to Lake Marie. Follow the Skyline trail along the ridge, bypassing the Buckeye that you ran up. Stay on Skyline as it winds down the ridge and exit via the River-Ridge trail that you came in on. (A shorter variation of this route can be done by turning right on Skyline and heading down immediately after reaching the top of Buckeye). Source
