I hiked this trail and it is amazing. Definitely not 8.5 miles. I clocked 10.7 miles, so be prepared. Lots of it is shaded. You will see frequent changes in the ecosystem. This is a mountain biking trail and I was the only hikers I came across.

Great trail. Lightly trafficked this past Sunday. Fairly easy terrain. Lots of ticks. Found at least 12 of them on my pup. It’s tick season, not much I can do about it.

Fun loop trail. Easy quick get away.

Be aware that the trail is closed at Carson Falls - a posted sign says trail closed due to hazardous conditions. This hike is in a beautiful area but the trail map needs to be edited and updated for accuracy. I deleted my recording due to trail map errors and will record an alternate route next time.

Nice loop trail with great views and some shade.

I picked this hike since it was dog friendly and on the shorter side though with a view of two lakes. Overall it was a good hike with some nice scenery though a couple more moderate sections with inclines. After, we drove to the Bon Tempe dam and after seeing the scenery there I wish we took the extra time to hike around that lake instead. However, for a less than 3 mile hike that is dog friendly and scenic, I recommend this trail.

A nice travel with good vantage points and a the chance to see some wildlife.

Make sure to put on sunscreen as there are no shades for the first 1.2 miles. Just like what another reviewer mentioned, Liberty trail was not clearly marked and looked like it hasn't been used often lately. I had to check my GPS to make sure we're still on the right trail. Lots of bugs along the trail: make sure to spray bug repellant. I would go back here in spring when it will be cooler and more water at the falls.

Was on our way to Cataract Falls, but found this instead at the road closure. It was absolutely beautiful especially after new rainfall.

My family and I found this wonderful trail in April of 2016 when we couldn't get to Cataract Falls due to a rock slide closing the road. But we were happy we found this gem. And the fact that it was raining when we hiked it made the falls just that much more amazing. The views were amazing and it was decently challenging. Be on the lookout for the poison oak! There was quite a bit. And as an added bonus: Salamanders!

Great work out! A lot of waterfalls. Took advantage after the rain.

So beautiful! Great variety of up and downhills. The weather was beautiful during February and not too hot! It had just rained a lot and the waterfall was full and gorgeous

Great hike - as Erika stated - road closed at golf course however that was ok bc far less people (as in one) for the first few hours - the views up Pine Mountain road were amazing - falls were nice but as you can see from the pictures you cant get that close - do yourself a favor, go down the little carson trail for a few minutes, really pretty - little muddy at Old sled road at the bottom, if I had to do it over again I would have done an out and back. Happy trails

The road to the trail head was closed to cars at the golf course, leading to a pleasant 1.3 mile walk along the Fairfax-Bolinas road to the Azalea Hill Trail Head. We enjoyed the exercise and views on the way up to Pine Hill on the Pine Hill Fire Rd, and the beauty of Carson Falls after the big rains. On the way home we took the 1 mile Old Sled Rd back to the Bolinas-Fairfax road. The Old Sled Road included some rough terrain, but was free from people and lead us through a variety of environments and along a rushing stream. It also allowed us to create a loop out of the hike. The Old Sled Rd trail head is on the Bolinas Fairfax Rd, around 2.5 miles from the golf course where we parked. Since the road was closed (maybe this is the case on the weekends?) it was a nice walk on the road back to the car. This is a great hike for a sunny winter day!

we extended and took the fire road to nail trail before meeting up with little carson falls. portions of this hike are amazing - liberty trail and nail peak were both beautiful, interspersed with some fire road hiking. Also a quick hike along bolinas faifax road is required to link up the reservoir trail and liberty. The waterfall is gorgeous right now.

Excellent. Good mixed of technical, climbs with switchbacks and rolling downhills.

Beautiful views of the North Bay and lovely wildflowers; but be careful -- the trails aren't well marked (esp. the Liberty Trail -- which seems like hardly anyone ever goes on)!

Also, note: Even though it says that the road is closed, hikers and bikers can still go on the trails (just not cars).

Breath taking views, wild flowers and fresh air. Waterfall was minimal but still nice hike.

Friday, April 29, 2016

Yes wild flowers were good this time of year 5/28/16

It is a challenge with the steep hills and stairs but well worth it!!!

Sunday, February 21, 2016

Amazingly beautiful! Big waterfall with many levels. A tough hike but worth it indeed. Will go again!

Difficult at times but great single track mountain bike course. Must have permit to bike here, Rangers spot check on trail. Easy to get day permits at local bike stores.

Bring lots of ICE! A sentiment I overheard from an anonymous young rider and fully endorse was "get me off this bitch!" You'll be lured by the climbs which are nothing; maybe 1000' vert and not steep. The trail however is pure gnarl. The most critical apexes of the numerous switchbacks are narrow and littered with huge boulders. Many turns are so sharp and vertical that you cannot put a foot down. So whether climbing or descending you're going to need lots of brake and a lower than normal saddle height. Before even starting the ride I saw one guy with a pinch flat, another with a snapped handle bar with his arm in a sling, another with a bent derailleur hanger. On the top of the ascent which I survived, I mentioned to my buddies that there was probably no dearth of helicopter "life flights" out of this place. Indeed I had my own near death experience on the descent. I have a Cannondale Flash 29er hardtail On Sat. I would have given a left nut for a full suspension rig. The rock gardens are numerous I started getting tired and went over the bars. I cartwheeled over boulders rag dolling for a good 10-15 feet. My back, shoulder, right elbow (contused), knee (contusion) and left wrist (contusion) got scraped and bruised up good (no breaks thank you sweet Jesus.) Returned to my bike to find both hydraulic brake actuators had disengaged from the plungers, handlebars off center by 20 degrees and chain off. I continued my folly by attempting the decent conservatively, that is with plungers attached to the brake actuators with constant hand pressure. Somewhere along the trail the brakes lost all pressure. I didn't make this revelation till hurtling toward a switchback and lost all brakes. I laid it down, snapping a finger and further embedding unneeded gravel and branches into my torn flesh. Crowded, exposed and potentially deadly. The ice? Ice that shit after you crash. You'll heal much faster.

Just to be clear, there is no actual trail called "Tamarancho Trail". Tamarancho is a system of trails located in Fairfax that is maintained by both the Boy Scounts and Volunteers (go on Sundays and help out!). It is Mountain Bike focused (which is a breath of fresh air in a place like Marin), but is open to hikers as well. The trails are 100% single track except for the new Flow Trail, which is a wider double track. There is not a single trail there for beginner bikers. Every trail is Intermediate to Advanced. Nothing overly difficult, but definitely challenging. The new Flow Trail is amazing and a great way to both test and develop your mountain biking skills. An important note is that most people ride the trails in a loop and do so clokwise. If you go counter-clockwise you will end up complaining that you had to get off your bike too many times to accommodate the other trail-users going the opposite direction of yourself. Another important distinction is that to ride these trails it is good etiquette to PAY FOR YOUR USAGE. You can get a day pass for $5 or a season pass for $45 (good for a full year) at Sunshine Bicycles in Fairfax. Paying for your pass helps to keep the trails maintained and fun to ride. You can also get your pass at the link I have attached. Happy riding!

Did this trail a while back. As mentioned the trail is a fire road for the first 1-2 miles. There are some views but the best option is to come in late April / Early may when the falls are still "falling" and the wildflowers are out.

Great switch backs and diverse terrain. Definitely challenging yet not bad for an intermediate rider like me.

This is great mountain biking riding and some might considerate demanding. The first climb up to the Pine Mtn. junction is very technical. The Repack downhill is a blast.
