Cascade features a collection of good quality andesite boulders. A large range of sizes and problems from VB-V9 so far, with many more lines waiting to be sent. The boulders are scattered over a 1/2 mile area, so it can be a little challenging to find them. The Northwest Oregon Climbing book has a map, and you can find maps online as well. Most boulders have good landings, although a few have spots that require a couple of pads or a good spotter. Tends to be fairly dry year round, so it can be a good spot to go during the winter dry days, yet its shaded during the summer so it stays cool during hot days. I marked the main boulder areas fairly accurately, so between the location markers and directions, you should be able to find the boulders fairly easily.
Take the Cascade Locks exit off of I-84. 1. Head northeast on US-30/Wa Na Pa St toward SW Cascade Ave Continue to follow US-30 0.8 mi 2. Continue onto Frontage Rd 2.3 mi 3. Turn right onto Herman Creek Rd/Wyeth Rd 0.2 mi - You will see a gate on the west side of the road with a yellow reflector on it. Park next to this, and follow the road back. the boulders can be a bit tough to find if you don't have the map.
