Haystack Rock is the free aquarium every Oregon coast road trip should include. The 235-foot basalt sea stack rises from the beach at Cannon Beach, and at low tide its base becomes one of the most accessible tidepool areas on the West Coast. The rock is basalt from lava flows roughly 15 million years old; since 1990 the intertidal zone around it has been protected as a state Marine Garden, and the rock above the high-tide line is part of the Oregon Islands National Wildlife Refuge. Walk out an hour or more before low tide and you will find ochre sea stars, giant green anemones, crabs, chitons, limpets and, if you look closely, nudibranchs. Overhead, the rock is a protected seabird nesting site: tufted puffins nest on the grassy north slope from April through July, with June and July the best viewing, alongside pigeon guillemots, common murres, black oystercatchers, gulls and cormorants. From mid-February to late October, the Haystack Rock Awareness Program sets up on the sand during daytime low tides with interpretive staff, microscopes for small organisms and spotting scopes for the birds, which turns a beach walk into a guided marine biology lesson. The rules are strict and worth respecting: no climbing above the barnacle line, no removing animals or materials within 300 yards of the rock, and walk only on sand and bare rock. Honest framing: everything depends on the tide and weather; at high tide or in winter storms, there is little to see and the surf is dangerous. Fit: families, couples, road-trippers, and anyone who loves aquariums enough to see the real thing.
Timing is everything. Check a tide chart (available online, at City Hall and from local businesses) and plan to arrive an hour or more before a low tide, ideally a minus tide in late spring or summer. Morning lows in summer combine the best tides with calmer winds and the puffin season.
Treat it like the world's best touch tank with stricter rules. Step only on bare rock and sand, avoid the mussel and anemone beds, touch gently with a wet finger if at all, and never pull an animal off a rock. The volunteers of the Awareness Program are happy to show you what you are looking at, and their microscopes reveal the tiny creatures most visitors miss. Film fans will recognize the rock from The Goonies, and the Needles, three smaller sea stacks just to the south, frame the classic photograph.
Practicals
Access to the beach is free; park in town and walk down to the beach near the rock. Never turn your back on the ocean, especially with children. Pair it with the Seaside Aquarium a few miles north, or drive south on US-101 to the Oregon Coast Aquarium and Hatfield Marine Science Center in Newport.
What to expect
The experience
Natural tidepools at the base of a 235-foot sea stack — sea stars, anemones, crabs and nudibranchs at low tide, nesting puffins in season, and seasonal volunteer naturalists on the sand.
Best time
An hour or more before low tide; minus tides in late spring and summer are best, and June and July are prime puffin months.
How long
One to two hours around a low tide.
Tips
Check the tide chart first. Stay below the barnacle line and on bare rock. Bring binoculars for the puffins and never turn your back on the waves.

Good questions
When is the best time to see the tidepools?+
An hour or more before low tide, ideally a minus tide in late spring or summer. Check a tide chart before you go.
When can I see puffins?+
Tufted puffins nest on the rock from April through July; June and July are the best months, on the grassy north slope. Bring binoculars, or look through the spotting scopes the Awareness Program sets up on the sand.
Can I climb Haystack Rock?+
No — climbing above the barnacle line is prohibited, and nothing may be removed within 300 yards of the rock.
Are there guides?+
Yes — the Haystack Rock Awareness Program runs from mid-February to late October during daytime low tides, with staff, microscopes and spotting scopes.
Is it free?+
Yes — Oregon beaches are public; you only pay for parking in town where it applies. Public lots near downtown Cannon Beach fill early on summer weekends, so arrive ahead of the low tide rather than right at it.
