The view wasn’t super stunning, but It was worthy long hike! Good outdoors exercise! Make sure you wear hiking boots and stay on the trail. We saw a rattle snake in the grass.

Decent hike. Some veiws but nothing spectacular and to close to civilization for me.

Nice uncrowned hike shared with more mt bikers than fellow hikers. Mix of sun and shade with nice views. Cool Karma Kit ( left bug repellent; didn’t take anything but what a great idea!) Ate lunch in the garden afterwards lots of benches and shade. The trails branch and you’ll have your choice of various routes.

Very nice 2 hour 45 min hike. Trails were all maintained very well. Deer, turkeys, rabbits. There were two “karma kits” for hikers and mtn bikers...air pump, snacks, water. Lots of loose gravel, wear hiking boots rather than running sneakers.

This trail is long, steep, and rocky. especially if you do the whole loop including Tutor loop.

I have done this trail several times. In fact, I helped build and maintain parts of it when ole Ken Thatcher was taking work parties up (I would say that somebody needs to do maintenance on the K. Thatcher trail--sections need it badly). I usually go clockwise direction; but as one reviewer stated, the trail on the back side of Sugarloaf is pretty steep going downhill. It's quite doable however. Wear better hiking shoes/boots; not tennis shoes (unless you like skiing down). And definitely bring enough water. Watch out for snakes (rattlers that is). Poison oak and poky thistle weed are everywhere. Ticks too, though most are gone after end of May (until the rain starts going in Nov.). That's why I recommend long pants. Of course, check out the other hikes offered. This one is the big one, which is rarely used (and that's why I like it).

Upper Skyline Trail is a beautiful start to your trek, and allows you to get the climb in elevation done first. It's also nicely shaded. If you decide to add Thachers Rim Rock trail to your trek, be sure to bring extra water. I highly suggest starting Rim Rock at the entrance south of Lake Marie because there is a steep climb on the south end, and it is easier to find footing climbing up than trying to crawl/slide down. Rim Rock is an ass kicker. There is a lot of steep trail with little to no shade. It's a near climbing crawl for the first mile or so, followed by breathtaking views and a nice cool-off period, then followed by a somewhat gradual and occasionally steep decent. Again, don't be caught without ample water supply. Rim Rock is the most stunning trail at Skyline for those willing to pay the toll.

Great hike with climbing elevation during the first half, followed by a nice and gradual descent and cool-off period for the last half. Nice mixture of sun and shade throughout. On warm days it's helpful to carry a bottle of bug spray in your back pocket for those pesky flies. Careful during the rainy season, as a good portion of the trail covering the first half of the hike has seasonal streams running directly through the pathway.

Excellent hike. The parking gate opens at 7am and there is a small $5 parking fee. The attendant was extremely friendly and helpful. She provided a map and an overview of the tricky parts of the trail. At the start, I saw a few deer and a flock of turkeys. The initial part of the hike had some strenuous elevation, which warmed me up quickly. The trail was well marked and well groomed. It was a little bit rocky. I did some different trails than the route originally stated, but it was well worth the diversion.

We did this trail clockwise as others have suggested. The climb up is a great workout!!! This loop offers plenty of up and down with some shady spots. I would not recommend on a sunny hot day if you are not a lover of the heat. One of the peaks has been damaged by fire. It is very barren and the trees are intriguingly scared by fire damage. Very desolate and hot but then a nice decent into partial shade. Nice views overlooking the towns below. We saw deer and turkeys. Had a deer jump out from brush and scare the life out of me!!! The abrupt, furtive movement had me thinking Mountain Lion ....it ruined my Zen for a moment :0/ Get out and hike!!!

Nice view the whole way. Not a difficult trail, had fun and no mosquitoes just flies :)

Good steep climb over all. Counterclockwise is best if you want the steep challenge. The last half of the trail has lots of prickly plants that line the single-track trail. I wore shorts and have red bumps on my legs, I would recommend wearing pants. Otherwise great views and worth the challenge.

Did this hike with a 6 year old took us 4 hours but he set the pace a full grown adult could do it in 3 and an athlete can do it in 2 if he jogs. Came across 2 rattle snakes and spotted a mountain lion at a distance

A super sweet calm stroll

Trail well maintained. Good hike for the early morning before it starts to get warm.

Absolutely gorgeous hike in the spring. Tons of wildflowers and gorgeous views looking back at the valley. I followed other’s recommendations and went clockwise (less marked trail head this way) and can’t say I would recommend one way over the other. Definitely watch the app carefully if you are determined to follow this exact route. Trails are easy to find but I added about a mile extra to my hike by missing turns and ending up on wrong trails. Not sure if this is “heavily trafficked” for Napa standards but middle of the day I think I saw 10 people. It was serenely quiet. Definitely will come back and try more!

Sunday, April 14, 2019. Parking fee: $5. It was a sunny day with refreshing breezes. The trail is mostly unshaded. The loop half way through the trail (before climbing up Sugarloaf) was closed to horses and bikes. In a few places in that loop trees have fallen and blocked the path. Other than that everything was great! Wild flowers, birds chirping, etc. I finished up the whole trail in less than 4hrs.

Beautiful wildflowers and green hills. A little muddy, but manageable. Great signage, although it doesn’t appear to match the map they give you at the info station. We will hike this again!!

Great trail some of the conditions in early spring are still muddy and some river crossings are washed out so take precautions and ensure necessary footwear. Cost is $5 to get in and I’d also recommend coming here once rainy season is over because the flowers are beautiful!

I’d recommend this to people who like a challenge. It was more than medium but not real hard. Rocky in parts and gravelly, but mostly dirt. The trail up to Sugarloaf was narrow and steep but slow and easy was good. Would not take my dog on this but maybe if you have a dog that is used to rocky hikes. Very quiet and great views of hills and valleys. Not too busy on a February Saturday.

This is not a technically difficult hike. It climbs in elevation the first half of the hike, so it’s somewhat strenuous. Trail is level and flat though. It was safely done with a one year old and 3 year old on our backs.
