I am looking to hike part of Oregon and all of Washington in 2018. It has been suggested to hike the Oregon Scenic Trail around the worst sections of volcanic rock (Three Sisters?) since I will have my dogs. Can anyone offer any advice about the best place to leave and rejoin the PCT south and north of the volcanic rock section. I can't seem to find any information on the OST except on Wikipedia which isn't super helpful, and no maps at all
