The first story I ever filmed in Alaska for National Geographic was tide pooling in Port Protection, Alaska. Gary Muehlberger, a subsistence hunter and gatherer, wanted to go octopus hunting. We went out on a big minus tide, Gary found a hole in the rocks, there were bones from its prey piled out front like a little graveyard. He blew a hose into the hole and forced the octopus out. I was completely blown away, not just by the octopus, but by how much life was hiding in every crack and crevice around us. Sea stars. Anemones. Chitons. Creatures I’d never seen outside an aquarium, just sitting there waiting to be discovered at low tide on a Southeast Alaska beach.
I’ve been obsessed with tide pooling in Alaska ever since.
Alaska has more coastline than the entire rest of the United States combined, over 34,000 miles of it. A good chunk of that coastline is rocky, tidal, and absolutely teeming with life. In Southeast Alaska alone, scientists have counted at least 170 species of macroscopic invertebrates in the intertidal zones. Here’s where to go and what to look for.

Why Alaska Tide Pooling Is Different
Most people who have tidepooled in California or Oregon think they know what to expect. They don’t. Alaska’s intertidal zones are different in scale, in diversity, and in the sheer drama of the tides.
The highest tides in the US can be found south of Anchorage on Turnagain Arm, with tidal ranges up to 40 feet. Kachemak Bay near Homer sees swings of up to 28 feet. Ketchikan’s tidal range regularly exceeds 17 feet. What that means practically: at a good minus tide, you’re walking out onto a section of seafloor that’s normally deep underwater. The creatures you find at -4 or -5 tides are things most people have never seen outside an aquarium.
The cold, clean water is the other factor. Alaska’s intertidal zones support marine life that warmer, more polluted coastlines can’t. The nudibranchs are more colorful. The anemones are bigger. The sea stars are still abundant in many Southeast Alaska locations.
Understanding Alaska’s Minus Tides
Tide pooling in Alaska is all about timing. Low tide is when the pools are exposed, but not all low tides are equal.
A standard low tide might drop to 0 or +1 feet. That exposes the upper and mid intertidal zones: barnacles, limpets, mussels, hermit crabs. Good but not spectacular.
A minus tide drops below that baseline. A -2 exposes the lower intertidal zone: anemones, sea stars, chitons, nudibranchs, urchins. A -4 or -5 exposes the subtidal fringe, creatures that are normally always underwater. Chitons clinging to rocks. Christmas anemones in red and green. Opalescent nudibranchs with waving orange fringes. If you get a -4 or -5 on a calm clear morning, you’re having a genuinely extraordinary day.
How to check tides: Tides.net has Alaska-specific tide predictions for every major location in the state. Check for minus tides in your travel window and plan your day around them. The best minus tides in Alaska typically fall in May, June, and July in the early morning hours.
What You’ll Find in Alaska Tide Pools
Nudibranchs
Sea slugs that look like someone spilled a box of Halloween decorations on the ocean floor. Opalescent white with orange fringes. Lemon yellow. Electric blue. Some of them are less than an inch long and look like they were designed by Dr. Seuss on magic mushrooms.
Sea Stars
The celebrities of the tide-pool. Purple, orange, and red, from the size of your palm to the size of a large pizza. Alaska’s sea star populations took a significant hit from sea star wasting syndrome but Southeast Alaska still has strong populations in many locations.
Chitons
Oval armored creatures that look like a boat turned upside down, clamped to rocks with surprising strength. Ancient animals, chitons have barely changed in 500 million years. They’re found at lower minus tides, gripping the rock at the subtidal fringe.
Giant Green Anemones
Bright green columns with waving tentacles that look like something from a Cronenberg film. Fully extended at low tide they’re one of the most visually striking things in an Alaska tidepool. Touch the tentacles gently and they’ll close around your finger, like they’re trying to eat you!
Pacific Octopus
The holy grail of Alaska tide-pooling. They’re there, hiding under rocks, wedged into crevices, watching you with unsettling intelligence. Finding one is rare and memorable. Look for the telltale pile of empty crab and clam shells outside a rock crevice, that’s an octopus den.
Sea Urchins
Purple spiny spheres wedged into rock crevices. Common in Southeast Alaska, especially at lower minus tides. The inside is edible uni, if you’ve had sushi you know. Collecting requires an ADF&G permit.
Hermit Crabs
Tiny chaotic landlords hauling borrowed shells across the pool floor. Kids love them. Adults love them too. Watch long enough and you’ll see two of them negotiate a shell swap. I used to love shooting underwater time-lapses of these guys, they are busy busy crustaceans.
Gumboot Chitons
The largest chiton in the world, up to 13 inches long, rust-colored and lumpy. Found at extreme low tides. Locally called “wandering meatloaf”, a very apt nickname.
Best Tide Pooling Spots in Alaska
Petersburg Area Beaches
Petersburg sits in the middle of the Tongass Rainforest surrounded by some of the richest intertidal habitat in Alaska. The beaches on Mitkof Island at minus tides are exceptional and accessible by car or bike from town. I’ve spent a lot of time in Petersburg filming and the tidepool life around the island is extraordinary.
Prince of Wales Island
This is where it all began for me. There’s a reason NatGeo wanted a show here, it’s remote and extraordinary. The outer coast beaches of POW Island at extreme minus tides expose intertidal and subtidal zones most people never see. No crowds, no infrastructure, no place like it. You’ll need local knowledge and a vehicle. Worth it if you’re spending time on the island.
Rotary Beach — Ketchikan
About 3 miles south of downtown Ketchikan, Rotary Beach is a beloved family spot with excellent tide-pooling along its sandy and rocky shore. At low tide, sea stars, urchins, hermit crabs, small octopuses, and clams are commonly found, often with bald eagles overhead. Easy public access by road or bus, restrooms on site. One of the most accessible and consistently productive tidepool beaches in Southeast Alaska.
Auke Recreation Area — Juneau
About 15-20 minutes north of downtown Juneau, Auke Rec Beach offers sheltered, family-friendly tide pools along its pebbly and rocky shore. During minus tides, explore for sea stars, anemones, urchins, crabs, sculpins, and small fish. Scenic views of mountains and islands, free parking, picnic shelters. Good for beginners and families.
Bishop’s Beach — Homer
Just minutes from downtown Homer, Bishop’s Beach is one of Alaska’s most accessible and popular tide-pool spots, perfect for families with easy parking and a wide, walkable shoreline. At minus low tides, rocky areas and cobble beaches reveal sea stars, anemones, hermit crabs, chitons, mussels, barnacles, and occasional octopuses amid dramatic views of Kachemak Bay and volcanoes.
I lived on the Homer Spit for three years filming Alaska: The Last Frontier and spent more low tides than I can count on Bishop’s Beach. The views across Kachemak Bay to the mountains are as good as the tide-pooling.
Kachemak Bay State Park
The best tide-pooling on the Kenai Peninsula is across the bay from Homer, accessible by water taxi from the Small Boat Harbor. China Poot Bay and Jakolof Bay both have exceptional intertidal zones at minus tides. The Alaska Maritime National Wildlife Refuge runs guided tide-pool tours, worth booking if you’re there. Call ahead: (907) 235-6546.
Lowell Point — Seward
The tidal variation in Seward is 16 feet, leaving a lot of exposed and safe shoreline to explore when the tide is low. Lowell Point, a short drive south of downtown Seward, has excellent rocky intertidal habitat. Good base if you’re combining tide-pooling with a Kenai Fjords boat tour.
Fort Abercrombie State Historical Park – Kodiak Island
While exploring the World War II ruins at Fort Abercrombie State Historical Park, pop down to the beach at low tide for excellent tide-pooling. Sea anemones, sea stars, and crabs are commonly found, along with whales and sea otters visible offshore. One of the more unique tide-pool settings in Alaska, WWII gun emplacements above, sea stars below.
What to Wear and Bring Tide Pooling in Alaska
- Footwear: XtraTufs or waterproof rubber boots with good traction. The algae on tidepool rocks is genuinely slippery — more people go down on tidepool rocks than you’d think. Do not wear flip flops. Do not wear fresh sneakers you like.
- Layers: Southeast Alaska is cold and wet even in July. Bring a rain jacket, a mid layer, and waterproof pants if you have them. You’ll be crouching over pools for longer than you think.
- Gloves: Optional but useful for handling rocks and keeping your hands warm in cold water.
- Tide chart: Check Tides.net before you go. Don’t show up at high tide and wonder why there’s nothing to see.
- Field guide: The Audubon Society Field Guide to Pacific Coast covers most species you’ll encounter in Alaska’s intertidal zones. Worth having.
What You Can Eat From Alaska Tide Pools
Tidepooling doesn’t have to be purely observational. Southeast Alaska’s intertidal zone is one of the richest wild food environments on earth. Here’s what’s edible and what to know before you harvest anything.
*Critical warning: Paralytic Shellfish Poisoning (PSP) is real and it can kill you. Toxic algae blooms make mussels and clams dangerous to eat without warning. ADF&G issues closures regularly and they change fast. Check the ADF&G shellfish hotline before harvesting any bivalves.
Butter Clams
Butter clams are the digger’s reward, buried just beneath the surface of sandy and gravelly beaches, they give themselves away at low tide by the small dimples and keyholes they leave in the sand. They can be spotted by the squirts shooting up from the sand. Dig down a few inches with your hands or a small shovel and you’ll find them, thick-shelled, cream-colored, up to 5 or 6 inches across. They’re considered one of the best clams for chowder in Alaska, with a sweet, clean flavor that comes through even in a simple steam with butter and garlic.
Blue Mussels
Blue mussels blanket the rocks in clusters of hundreds of individuals and are one of the most common residents on Alaska’s shoreline. Steam them with butter, white wine, and garlic and you have one of the better meals you’ll eat in Alaska. Free, abundant, and delicious.
Sea Urchins
Purple sea urchins are abundant in Southeast Alaska at lower minus tides. The roe inside, uni, is the same product served at high-end sushi restaurants for $30 a piece. Harvesting requires an ADF&G sport fishing license.
Gooseneck Barnacles
Gooseneck barnacles, or dragon toes, are a rare seafood delicacy. Fresh, the meat tastes like crab or lobster. They canvas nearly every rocky outcrop of Baranof Island’s outer coast near Sitka and are found throughout Southeast Alaska’s outer coast at extreme low tides, clinging to wave battered rocks in clusters.
Alaska has no established commercial fishery for gooseneck barnacles — check ADF&G before collecting any.
What you cannot take:
Sea stars, anemones, nudibranchs, chitons, hermit crabs, and octopus cannot be removed without an ADF&G Aquatic Resource Permit. These are not food animals under Alaska sport fishing regulations and they’re protected intertidal species. Look, photograph, leave them where they are.
Alaska Tide Pooling Rules and Ethics
- Replace rocks exactly as you found them. The organisms living on the underside of a rock die if it’s left flipped over. Turn rocks gently, look quickly, replace carefully.
- Don’t stand in the pools — walk on bare rock whenever possible. You’re heavier than you look to a sea star.
- Watch the tide — minus tides come back in fast and the rocks between you and the beach get covered quickly. Know your exit route before you wade out to the low tide zone.
- Don’t remove marine life without an ADF&G Aquatic Resource Permit. This includes sea stars, chitons, and anemones. You can look, you can photograph, you cannot take.
- Leave no trace — pack out everything you brought in. Marine debris is a genuine problem on Alaska’s coastline.
Tide Pooling in Alaska FAQs
When is the best time to go tide pooling in Alaska?
During minus tides — when the low tide drops below the standard baseline. A -2 or lower exposes the lower intertidal zone with the most interesting creatures. The best minus tides in Alaska typically fall in May, June, and July in the early morning hours. Check Tides.net for Alaska-specific predictions.
What will I find in Alaska tide pools?
Sea stars, giant green anemones, hermit crabs, nudibranchs, chitons, purple sea urchins, mussels, limpets, barnacles, and with luck, a Pacific octopus. At extreme minus tides in Southeast Alaska you can find gumboot chitons — the largest chiton in the world — and Christmas anemones that are only visible a few times a month.
Where is the best tide pooling in Alaska?
Rotary Beach in Ketchikan and Bishop’s Beach in Homer are the most accessible. For serious minus tide exploration, the beaches around Petersburg, Prince of Wales Island, and Kachemak Bay State Park across from Homer offer the most diverse intertidal zones.
Can I take things from Alaska tide pools?
Some things yes, some things no. Sea stars, anemones, nudibranchs, chitons, and octopus cannot be removed without an ADF&G permit. Look, photograph, leave them. Mussels, clams, and urchins can be harvested with a sport fishing license within bag limits. Before taking any shellfish, check the ADF&G biotoxin hotline — Paralytic Shellfish Poisoning has no visual indicator and can kill you.
What shoes should I wear for tide pooling in Alaska?
XtraTufs or waterproof rubber boots with good traction. Tidepool rocks covered in algae are genuinely slippery. Don’t wear flip flops or fresh sneakers.
Is tide pooling in Alaska good for kids?
Yes! One of the best family activities in the state. Bishop’s Beach in Homer and Rotary Beach in Ketchikan are both easy to access with kids. The creatures are dramatic enough to hold a kid’s attention for hours. Bring rubber boots, a bucket, and a field guide.
