Meet sea stars, hermit crabs & a thousand tiny neighbors of the Pacific.

The neighbors you'll meet
The Oregon Coast's rocky intertidal zone is one of the most biodiverse on the Pacific. Here are a few of our favorite locals.
Ochre Sea Star
The bright purple and orange keystone of the Pacific intertidal — a single sea star can clear a patch of mussels and reshape an entire community.
Giant Green Anemone
Up to a foot across, glowing emerald green from symbiotic algae living in its tissues. Watch it slowly close around your finger if you offer it a gentle touch.
Hermit Crab
Tiny apartment-hunters who upgrade shells as they grow. Pick up an empty shell and you might be holding someone's next home.
Purple Sea Urchin
Spiky algae-grazers that carve perfect bowl-shaped homes into solid rock. Their population has exploded since sea star wasting disease hit in 2013.
Gooseneck Barnacle
Not a snail, not a clam — a relative of crabs that glued itself headfirst to a rock and now kicks food into its mouth with feathery legs.
Aggregating Anemone
Clones itself into vast colonies that fight territorial wars at the colony borders. The pink-tipped tentacles deliver a sting that'd be alarming if you were a fish.
I want everyone who walks the shore to see what I see.
I'm Mylasia — most people call me MyMy. I'm a marine biologist, a Texas A&M alum, and I've spent the last few seasons as a Tide Pool Ambassador on Cannon Beach. Now I'm starting my own small-group tours along Oregon's north coast.
Tide pools are tiny universes — and they're more fragile than they look. On every tour, you'll learn the names of these creatures, how they survive the pounding surf, and how to enjoy them without ever leaving a footprint behind.
Four favorite stretches of Oregon's rocky coast
Each beach has its own personality — and its own residents. We pick the location for each tour based on tide conditions, group size, and what's been showing up that week.
Cannon Beach
Iconic 235-foot sea stack with one of the most accessible and biodiverse tide pool areas on the Oregon Coast.
Indian Beach
A sheltered cove inside Ecola State Park with rocky outcroppings and excellent intertidal life.
Seaside Cove
The southern edge of Seaside, where the rocky shoreline begins. Great spot for sea stars and anemones.
Hug Point
A short walk south reveals waterfalls, sea caves, and tide pools tucked into the cliffs.
Arcadia Beach
Tide pooling at Arcadia Beach State Recreation Site feels like stepping into a hidden miniature world, where low tide reveals colorful sea stars, anemones, crabs, and tiny fish tucked among rocky shelves beneath dramatic coastal cliffs.
