From Seattle or Bellevue, follow SR-520 East to the end of the freeway in Redmond. 
Continue straight, as SR-520 becomes Avondale Road NE. 
After a little less than one mile, make a gentle right turn onto NE Novelty Hill Rd. 
Go 2.2 miles, then turn left onto the entrance road, just opposite 218th Ave NE. 
Check-in will be adjacent to the parking area.

Parking onsite is very limited and is likely to fill up, so please carpool if possible. The gravel lot is reserved for equestrians and other park users, so please do not park there. Later arrivals will need to off load gear and passengers and then park off-site, about 0.7 miles away. Please allow adequate time to park offsite.

To search for a map on the web, enter the address:      21798 NE Novelty Hill Rd, Redmond, WA 98053
That is the south entrance.
