I've heard that the in-person staff are great but I didn't get to experience that. Actually, I should say that their website is so extensive that I didn't need to go in person (though I always love that experience, the timing just didn't work so I was grateful for the website).
Friendly person helped us with maps and fun places to visit. Cute town. Lots of history in the area. Also they have a driving loop that takes you to Oregon, Astoria, Long Beach and back to Cathlamet. Nice brewery in the local Marina with great beer.
