Great hike but it is really long. Once you are down to the lake it seems like it will never end. I took two kids and we made it!

does anyone recall where the sundial is located on this hike? its an old stone Indian sundial which is off the trail itself. I think its on the ridge part above Forest Knolls.

Just a heads up the trail map at the trail head is different than the one posted here, so pick one or the other to follow.

Saw some nice doggos!

Beautiful, easy hike for a Fall day.

The trail is closer to 6 miles than 5 and the elevation was approximately 1200 ft. The trail is definitely a great for cold winter days as there is little tree cover.

This is in accurate. It was way longer than 7 miles and took over 4 hours to complete. Little bugs swarmed my head buzzing in my ears and the whole thing is steep up or down, so hard on the knees. The view of the lake was nice.

Some beautiful scenery but trail not well marked, a number of intersections with no clues as to what goes where. Restroom facilities gross.

Nice easy walk, good for all ages!

nice but steep at the front

Lots of trail options. Trails are diverse terrain and beautiful views on some. Phoenix Lake circuit was lovely.

I did this trail but started at alpine lake took the trail counter clockwise, the trail up winds in and out of large beautiful trees and many creek crossings, and waterfalls. nice wooden bridges to keep you from getting wet even during rainy seasons. Once you get to the top, the trail loses its beauty and other hikers disappears going down.
There is a creek crossing just past the lake that you might run into trouble during rains there is no bridge.

This is a fabulous trail. This trail leads to the East Peak of Tamalpais, and the views of the entire Bay Area from here are spectacular. We made it up to the Fire Tower in less than 2 hours. You cannot go into the Fire Tower but you can clamber all around it to see 360 degrees of views. There is also a paved loop trail around the peak that is about 20 minutes and provides more great views (and is great access for strollers or handicapped folks from the parking area nearby). We started the hike at about 9:30 am on a Sunday and there was no problem finding parking along Panorama Highway. We got to the peak at 11:15 am which was perfect because the fog had just lifted and we had gorgeous clear skies. Highly recommended hike!!

This hike is a gem! It’s an easy hike, no elevation changes, with beautiful views lol the way around.

Nice 8.2 mile hike. Some parts are steep, but nothing over the top

Rated as moderate but it’s actually a pretty good challenge

We decided to continue hiking on the first trail to the left, about half way on this trail and hiked all the way out to where it comes back out on the lake. It’s only a few miles but the various switchbacks are pretty killer if you go that way and it is not a loop trail. This was a little while before I got the app so I was not ready for it. Very pretty though!

One of the best hikes I’ve done in Mt Tam. You will go though many different types of forest and nature. The lake is really beautiful about halfway through.

We took a couple of detours and made it closer to a 12 mike hike in about 4 hours.

Highly recommend.

They are not kidding about this being a hard trail. I measured almost 9.5 miles. It took me a solid 3.5 hours with no breaks. I ran about a mile of it. Lots of steep stairs and inclines. Helen Markt Trail was a killer. I felt like it wasn’t going to end. This is definitely a tough one even for the seasoned hiker! Lots of beautiful scenery and wildlife: Bring lots of water and snacks.

Easy and gorgeous. Takes 1.5-2 hours.

Beautiful trail (would be amazing in winter and spring when water was running in the creek), but hikers need to be prepared for the amount of climbing or descending (depending on which way you travel). The 1000 feet of elevation change is accomplished over MANY stairs created with wood, dirt, and rock. While I was able to handle the descent, the uneven wood and boulders were tough on the knees and ankles.

Good fire road action. Great views and places to refill your water bottle along the way.

This is now one of my favorite hikes, the views on the way up are incredible, the hike itself isn’t that difficult other than rocks the entire trip. Very very private, only a few cyclists passed me near the top.
Parking is a bit sketchy, the start of the trail is a bit steep so don’t get discouraged, the steepness ends quickly.
If you like peaceful hiking this is the one for you

My second time doing this trail - felt harder this time! - but absolutely beautiful, quiet, incredible views along the way and from the top. Echo Karl's comments below - wear sturdy boots, bring at least 1L water per adult (and drink half on the way up!), and food to recharge at the summit. Trail is narrow, steep (the whole way) rocky, uneven, loose rocks etc). Leave the kids behind unless they really love hiking challenges. Saw two other hikers on my way up, otherwise just the sound of rocks and the occasional lizard or crow. Go solo - your mind will be refreshed. Allow at least 1:30 for ascent to the fire lookout, 45 at the summit to enjoy and refresh, and 45 to descend.

A real gem! Beautiful hike with plenty of shade including redwoods In one area. Not all of the trails are marked, the AllTrails map was appreciated. There’s currently a lot of poison oak and it’s buggy in some places since there’s still some water in the creeks. I can imagine it will be gorgeous in the winter after it rains.

Narrow, steep , and rocky pathway. Prepare yourselves with proper hiking boots, attire, hydration, and food. It might be wise to go in the early morning instead of midday.

Unfortunately there wasn’t an In-and-Out waiting for us at the top. The views of the city and the bay were breathtaking all the way up.

Beautiful trail with lots of different kinds of terrain. Pretty lake area and views of mt tam. Didn’t see any other people on the trail.

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.

Nice shaded paths, pretty much dry this time of year.
