Note: Google, Yahoo and Mapquest will all give slightly different directions, but are all within 5 min. of each other. Some of them are wrong (e.g. the google map from Mill Valley to the Lodge will take you thru a tennis court at the end of a dead end road. Following are our recommendations.

See Marin Map for more detail

San Francisco 1 hr. from airport, 36 min. from downtown

1. Take US Hwy 101 across the Golden Gate Bridge (no toll this direction)
2. Go 4 mi. toward San Rafael
3. Take the State Hwy 1 N. exit toward Stinson Beach/Mill Valley
4. Turn left in about 0.5 mi to continue on Hwy 1 - Shoreline Hwy.
5. Follow Hwy.1 (also called Shoreline Hwy.) signs about 3 miles
6. Right turn on Panoramic Highway on top of a ridge.
   (Hwy.1 continues downhill to the west and is signed for Muir Beach. Don't go there.)
7. Follow the ridge.
   (there will be views of the Pacific if it is clear) to another large intersection (Sequoia Valley Rd. and Muir Woods Rd.) in about a mile.
8. Continue on Panoramic Hwy. (double yellow lines) about 45 degrees left
   and signs to Mt. Tamalpais and Stinson Beach.
9. The Lodge is on the right:
   1.4 miles from Sequoia Valley Rd., Muir Woods Rd. intersection.
   0.9 miles from Madera, Monte Simas (large F) sign.
   100' past Marin View.
   
10. There is a parking area just before the Lodge with three yellow posts protecting a gas meter in the lot and just beyond, a small sign that says CAC that may be hard to see in the dark.
11. There is parking at either end of the lodge. Front door is on the north (far) side.
12. If you come to a large brown Mt. Tamalpais State Park sign on the left, or Mountain Home Inn you have gone about 150 yards too far.
