RV + the low tide
Tide pools by region
At low tide the ocean pulls back and a whole world appears in the rocks — anemones, sea stars, urchins, the occasional octopus. The trick is timing: you have to read the tide chart and arrive at low tide, which is exactly the kind of flexible plan an RV is built for. Here's where to go by coast, with each spot's best window, what you'll find, and a campground to base at. Tread carefully on slick rock, never take or pry off an animal, and check the tide before every visit.
Feel the coast
Go at low tide — check the chart first, and leave every creature where it lives.
Olympic National Park Tide Pools (Beach 4 & Hole in the Wall)
Summer brings the lowest minus tides
Giant green anemones · Sea stars
Cabrillo National Monument Tide Pools
Late fall through winter (roughly December–March) — convenient daylight low tides occur in the colder months
Flower-like anemones · Elusive octopus
Acadia National Park Tide Pools (Ship Harbor)
Spring through fall
Green sea urchins · Small sea anemones
Cape Perpetua Tide Pools (Captain Cook Trail Marine Garden)
Minus tides are best
Sea stars · Giant green anemones
Yaquina Head Tide Pools (Cobble Beach)
Best when the tide is out on a minus low tide
Orange sea stars · Purple sea urchins
Point Reyes Tide Pools (Sculptured Beach & Duxbury Reef)
Visit on a minus low tide, arriving at least an hour before the lowest point and heading back within an hour after it turns
Giant green anemones (to ~17 cm) · Ochre and bat sea stars
Channel Islands National Park Tide Pools
Visit on a low (minus) tide during daylight
Sea stars · Sea anemones
Tidepooling is timed by the tide table, not the calendar, which is why most of these entries describe a tide state rather than a month. What you want is a minus tide — a low that falls below the chart datum — and the useful ones happen on a schedule that has nothing to do with when you are free.
Two practical consequences. Arrive at least an hour before the low and work outward as it drops, because the return is what strands people. And check whether the good minus tides at your shoreline fall in daylight at all that season — on parts of this coast the lowest tides of summer happen in the middle of the night, which is the honest reason a place can be a poor visit in its best-sounding month.
