Skyline Wilderness Park is located in the hills immediately east of the town of Napa and rewards hikers with great terrain from oak forest and grassland to lakes and mountain tops. Winemakers know that Napa Valley is a great place to be all year round, hence it's possible to find great hiking conditions here on virtually any month of the year.

Love this trail. I live just down the road so go on it a lot. Definitely tons of wildlife - NOT the trail to zone out and listen to your music on! Pay attention to snakes, pigs, lizards, turkeys, and deer aplenty. I've never seen a wildcat but know many people who have! I like to go counter-clockwise to kick off the workout in high gear and then take it easy the rest of the time. Also a good out and back if you go counter-clockwise to the Lake Marie and back.

Great trail that takes you along Lake Marie and up to Sugarloaf with breath-taking views of Napa Valley and San Pablo Bay. Wear comfortable hiking shoes, bring plenty of water, and a snack. Expect to spend about 3-5hrs hiking.

With all the recent rains there was a lot of running water, it was peaceful.

This was a decent, somewhat strenuous hike. It is *extremely* dusty. The first quarter of the trail is deceptively easy. Rock Rim was the hardest part of the trail by far.

Love it, I run it at least once a week. Its an excellent interval workout, with fantastic views, especially if you take Skyline to the top to loop around and Chapperell on the way out. Bring water! IMPORTANT: *Keep attention though*, the place is not joking about the Rattlesnakes, Wild pigs, Coyotes, and Mountain Lions that they warn you about on the many signs on the way to the trailhead. I run into at least one or 2 of those things every week. Making Noise on certain parts of the trail or going in a group is a good way to avoid problems, but makes it less likely to see wildlife. The Coyotes will run away, The mountain lions are very shy, My eye is always looking in the trail grass for rattlesnakes, and well; The wild pigs are *a**holes (but rarely encountered) Have fun!
