If you are going north on I-5 take the woodland exit and go right, instead of going straight, take another quick right. Follow that road for about 15-20 min. Then see a split off of the road, look for a sign that says Haapa park go right. On that road take the first right, straight down the road then you will see it at the bottom. When you get there you will have to look for a trail, go on the trail until you get to the river, cross the river (not deep up to your knees is the deepest) to the island, the other side of that island is the hole. Hope this helps!
