Cape Perpetua Tide Pools (Captain Cook Trail Marine Garden)
Cape Perpetua, in the Siuslaw National Forest just south of Yachats, is a Forest Service gem where the Captain Cook Trail runs from Sitka-spruce forest down to a protected Marine Garden shoreline. With Cape Perpetua Campground right in the scenic area, RVers can walk the one-mile round-trip trail to pools full of sea stars, giant green anemones and purple urchins. It sits within Cape Perpetua Marine Reserve, Oregon's largest marine reserve, so the intertidal life is genuinely abundant.
Best low-tide window
Minus tides are best; plan to reach the pools about an hour before low tide — late spring and summer bring the lowest daytime minus tides on the Oregon coast
What you'll see
Sea stars · Giant green anemones · Purple sea urchins · Sea cucumbers, chitons and limpets

Explore it safely
You MUST check the tide chart and go only on a minus tide — plan to arrive about an hour before low tide, and remember tide times change every day. This is a protected Marine Garden, so observe only, never pry animals off the rock, and take only pictures. The basalt is slick with algae, so walk on bare dry rock where you can, watch for waves at Devil's Churn and Thor's Well nearby, and follow leave-no-trace.
