Some rock formations at Ruby Beach, not sure how the beaches or tagged now. It's been eons since I was out there. Shot some rolls of Tri-x at the numbered beaches back in the dark ages. The first two or three beaches at the north end of the strip we're worth visiting. Don't recall finding anything at the south end. I'm sure you already know this is tripod required shooting.

Have a mini rain forest right my neighborhood. On the brightest of bright days the light level is sufficient at ISO 400 to shoot hand held with my OMD-EM5. 3 to 4 stops worth of stabilization. This serious guys I see there are always toting Gitzo set ups, cost more than my camera.

There are many tiny rain forests what might referred to as a microclimates all around Puget Sound. For example, the trail to Little-Si where you pass through the lower area between MT SI and LITTLE SI. That space is very wet that looks very much like the Ho rain forest. Seahurst Park has several these microclimates. Very small and very wet. Cougar Mountain Coal Creek Area has a number of these. The network of trails can be accessed from Red town trailhead. Be sure to take a map. They used to hand them out at the trailhead noticeboard. I got lost in there once came out after dark 10 miles by road from my car.

What to wear on your feet? I wear Vasque Clarions but I don't recommend them for swamps. They are notoriously slippery on wet rocks and logs. Your boots are going to get wet. Places like REI sell some strap on devices inspired by crampons but not the same. Might be worth checking them out.

Don't forget the meadows. Be prepared to see elk in abundance. (It is also possible that you will see none.) I once spotted a huge herd. As I was moving to find a good spot for a picture, a car skidded to a halt, kids exited it yelling, "Deer! Look at the deer!" Instantly, some 200 elk turned away from the noise and, in so doing, presented me a vision of hundreds of elk butts. Anyway, be prepared for seeing some of these magnificent animals. It is possible that the rut will be in progress, so be careful to not piss off any of the bulls that you see.
