Mt. Tam Circumnavigation 9-miles, 900-ft elevation gain

  • to
  • Mountain Home Inn

    810 Panoramic Highway , Mill Valley, CA (map)

    37.909782 -122.577065

  • We'll meet in the public parking lot on Panoramic Hwy just opposite the Mountain Home Inn. My pointer on the clickable map above is accurate if you are unfamiliar with the parking lot.
  • This is a "classic" Mt. Tam loop that works its way west along the south side of the mountain towards Mountain Theater and then turns east along the shadier, forested north side leading to lunch at picnic tables by the summit parking area. A short, quick  walk to the summit is optional, if you feel the need. From there we return downhill on the south side to the parking area. We'll plan to return to the cars by 2pm before heavy commute traffic.

    As always:

    We combine enjoyment of the trail with respect for everyone’s time. A steady pace and we just keep going! If you are in the lead you will end up waiting at trail junctions. If you are in the back you will be asked to do your best to keep up with the group and at waiting points the group may move on as soon as you are within sight. Make sure this is something you will enjoy.

    Please always check your email the night before just in case there are any necessary adjustments. This is especially important if there are any weather issues. Cancellations due to weather will be posted by 10pm the previous evening.

    Give yourself time to find the trail head so that you arrive prior to the scheduled time. That is the time we head out on the trail. It would be disappointing to miss having you on the hike due to late arrival. You will be left behind if you are not ready to head out at the hike start time.

    Wear comfortable hiking shoes with good rugged soles that are well broken in.

    Duration: 5 hours

    Facilities: trailhead and at the lunch stop.

    Dogs?: none allowed

    Bring plenty of water. More than one bottle is usually a good idea.

    Dress in layers.

    Bring a snack/lunch.

    FOR car pools ...Car pool etiquette- Come prepared to drive, be aware that there may be no others wanting to car pool from your selected location or there might be a lot of people and everyone might want to ride. We determine who gets the rider seats by who has most recently been a driver in the past. This is worked out based by who shows up at the car pool location. We can't guarantee anyone a seat because we never know until that day who will show up. We do our best to work it out and make everyone happy but we need everyone to pitch in and help make it work!

    Then PLEASE if possible try to use the two locations below. The more locations we have the less effective we are and it's so much more complicated. Exceptions would be if you are not close to either location.

    Car pool locations:

    Coddingtown Library parking lot suggested leave at 7:15

    Petaluma-Lucky at the intersection of Lakeville and Caulfield Ln. Park closest to Payran St. suggested leave by 7:30

    General room of thumb...$5 one hour or less to trailhead $8 over one hour to trailhead Please insist your driver accept the money. It's to cover more than gas's the wear and tear on the vehicle. We like to take care of our drivers!
