You can search Horseshoebend Ranch on Google Maps for directions, however DO NOT TAKE interstate 142 (the greyed out route below) no matter what your phone tells you.
If your using Apple Maps, it will misdirect you unless you use these coordinates: (45.8211612, -121.0308734) or 2-98 Kamholz Rd. Centerville, WA 98613. See below for more detailed directions.
Coming from the west (Portland):
Follow interstate 84 to Biggs Junction, then head north on interstate 97 across the bridge. Follow interstate 97 to Van Holy rd. and take a left. Follow Van Holy rd. to Enyeart Rd. and take a right. Then take a left onto Horseshoebend Rd. and follow it all the way out. When you come to a tee in the road, take a right and continue straight on Horseshoebend Rd. and you will see signs for the front festival gates.
If you want to cross over earlier at the Hood River Bridge or Bridge of the Gods (Cascade Locks) follow interstate 14 until you get to interstate 97 and follow the directions above from there, or until you get to Lyle Washington and take Centerville Rd. out to 97 and follow the directions above from there. Again, DO NOT TAKE interstate 142 under any circumstances!
Coming from all other directions:
Navigate to interstate 97 and follow the directions above.
