From I-5 heading north:

As you travel along I-5 watch for signs to 405/Beaverton. Follow the signs to 405/Beaverton/Highway 26/Ocean. As you travel through a tunnel you are on Highway 26. Travel to the Cedar Hills Blvd. /Beaverton Exit 68 (NOT the Cedar Hills Exit). Follow the exit staying in the right lane; turn right onto Cedar Hills Blvd. Travel through the 1st light at Barnes Rd., and turn right at the 2nd light onto Cornell. Travel a short distance and turn right onto 107th Avenue (landmark – an auto repair/espresso shop). Rather quickly 107th takes a hard left turn and becomes Leahy Rd. Continue on Leahy less than a mile, watch for 97th Avenue on the right. Trillium Hollow is on the left just beyond 97th. You will see the sign. 9601 NW Leahy Rd, 503-297-1696.
