From Bellevue, take I-405 North to exit 23 for WA-522 to Bothell/Woodinville. Stay on 522 for ~12 miles, exiting on the right for W Main St in Monroe. Follow the 1st roundabout all the way around, then continue straight through the second roundabout to remain on W Main St. Continue straight and the road becomes Old Snohomish Monroe Rd. Continue for ~3 miles, turning right on 131st Ave SE at the sign for Lord Hill Farms. Follow the road down and to the right until you get to the parking lot at the far end (past the office and the main building).
