Take Interstate 5 to Exit #255 Sunset/Mt. Baker. Go east 3.9 miles to 1733 Mt. Baker Highway.
Cedar Tree House is the third driveway on the right past Noon Road. In daytime, you will see the Cedar Tree House sign on the mailbox post. After dark, look for the green, tree-shaped reflector tape on this sign (its the next driveway after the reflector peace sign & Tree Frog Night sign).
Come up the long driveway, passing a house and then the large greenhouse on your left. Shortly past the greenhouse you will see the large parking area, also on the left. Continue to the House at the top of the hill if you wish to drop your luggage (or have been assigned one of the four parking spaces by the House). Return down the hill to the parking area, parking in one of the marked spaces, and be sure to have your flashlight along after dark for the short uphill trail walk back to the House.
