As described on the "1st pigtail bridge boulders" page, park at the edge of the bypass road labeled with a "road closed" sign or alternatively, take the main road and park just after the pigtail bridge ends where you will see a pullout on the left side of the road. From here, walk up the road just 150ft from the parking area and look for a cluster of aspen trees on your left. Through these you will see a small wall where you can walk uphill for a minute and find the boulders.
