Great hike! Peaceful, beautiful and light traffic. I usually have my dog off leash, but I decided to keep her on leash and it’s a good thing I did because the trail is quite often only wide enough for one person to pass. I didn’t see any other dogs off leash either... best to keep your fur babies on a lead! Took about an hour and 45mins to complete. We paid $8 at the watershed kiosk to park in the Lagunitas parking lot. We set out on our hike clockwise, which had us in shade for the first half of the hike, and sun for the last half. Time your hike accordingly if you want to avoid the sun at its hottest! Alternatively, go counter-clockwise. There is a part of the trail that leads you to Sky Oaks Road. You could walk the road to the next trail, OR cross the road at the designated pedestrian crossing to continue hiking next to/somewhat above Sky Oaks Rd. Even though I live in Berkeley, I’d definitely come back to hike here again!

Very beautiful and enjoyable loop around the lake. Trail was slightly muddy but nothing terrible. The views are fantastic and there are a decent amount of other people on the trail.

Lovely trail with the perfect amount of shade and sun. We started on the sunny more exposed part and ended in the shaded more woodsy side which felt great. The lake was a bit low which was sad to see, but still beautiful none the less.

Shady and easy with options for expanding or shortening the loop. Not much poison oak.

The trail was well maintained overall and made for a great hike. A couple of rocky spots along the route and it contained one steep grade to climb. Parking was great.

This is a beautiful hike with great shade cover almost the entire route. The difficulty is very easy and the tree cover makes it an easy trail to ramble along on.

Fun, easy trail - lots of families, kids, and dogs out on the weekends hiking and fishing. Some nice spots to pull out camp chairs and enjoy lunch on the lakeshore.

Big fan of this straightforward loop trail. Gorgeous scenery, varied terrain, sparse population, easy parking, no bikes, roughly half of the loop is shaded, and easy to follow with the perimeter of the lake as our guide. A few important things to note: -DO NOT MISS the ticket machine by the ranger kiosk at the entrance to the Mt Tamalpais Watershed area! It's about 2 miles from the Lake Lagunitas Parking Lot and trailhead for this loop. We were unfortunately not paying attention, missed the ticket machines, and had to drive all the way back out the windy Sky Oaks Rd to purchase the $8 parking permit (and the machines don't give change!). Worth it, as you can get slapped with a worse fine otherwise. -Watch out for tons of red- and green-leafed poison oak in the late summer! If you stay in the middle of the trail you'll be mostly okay, but there are a lot of stray tendrils so high socks or long pants recommended. -No bikes allowed, which is nice for pedestrians, but be alert for trail runners, horses (and horse poop), and bees. Enjoy the loop! Lovely photo spots along the way and not too bad in terms of incline, though the whole lake perimeter felt definitely longer than 3.7 miles. Bring a hat and water bottle for the sunny days.
