463

Tucked away between Washington State and Vancouver Island, the San Juan Islands feel like a secret world where time slows down and nature takes center stage. I had the chance to explore these islands firsthand – and let me tell you, the vibe here is pure magic. Think misty morning ferry rides, orcas breaching at sunset, and quiet roads winding past lavender farms and hidden coves.

Each island has its own personality. San Juan, Orcas, and Lopez all offer wildly different experiences, yet share that same peaceful, off-the-grid charm. Whether you’re kayaking through bioluminescence, wandering through a sculpture garden in the forest, or hiking up to a mountaintop with panoramic views over the archipelago, this place delivers something unforgettable at every turn.

Here are 12 of the most amazingly unique things to do in the San Juan Islands…from personal favorites to hidden gems you won’t find in your average guidebook.

Top Must-See Places in the San Juan Islands

Looking for the coolest things to do in the San Juan Islands? Relax on the scenic shores of Rosario Beach, explore the natural beauty of Moran State Park, and embark on an unforgettable Whale-Watching Expedition. Discover the rich history of San Juan Island National Historical Park and take in the breathtaking island landscapes.

I know the San Juan Islands are spread across multiple islands, so I mapped out all my favorite spots below. Save this map to your phone so you can easily navigate between the hiking trails, whale watching launches, and charming village stops!

1. Trek Through the Wilderness of Moran State Park

Moran State Park on Orcas Island is a hiker’s dream, offering over 38 miles of trails that wind through dense forests and past serene lakes. One of the most rewarding hikes is the trail up to Mount Constitution, the highest point in the San Juan Islands.

From the summit, the 360-degree views stretch all the way to Mount Baker and the Canadian Gulf Islands. If you’re not up for the full hike, you can also drive to the top and climb the historic stone tower.

Last summer, I spent a full day here hiking, swimming in Cascade Lake, and spotting bald eagles. The combo of mountain air and freshwater swims was unbeatable. The park also has over 100 campsites, perfect for making a weekend of it. If you’re looking for a place to unplug and get moving, Moran State Park delivers on every level.

2. Encounter Majestic Orcas on a Whale-Watching Expedition

There’s nothing like seeing an orca breach just yards from your boat—and the waters around Friday Harbor and Orcas Island are one of the best places in the world to witness it. San Juan Safaris and Maya’s Legacy Whale Watching offer guided tours led by naturalists who share cool facts about the local orca pods, humpbacks, and even porpoises.

Many boats are equipped with hydrophones so you can hear the whales “sing.” The first time I went, I wasn’t expecting to cry—but watching a pod of orcas glide by at sunset hit me hard. The experience feels unreal.

Whale watching here isn’t just about seeing wildlife; it’s about feeling deeply connected to the Pacific Northwest. It’s ethical too—operators follow whale-wise guidelines to ensure a safe, respectful encounter. Add this to your list early—it often becomes the trip highlight.

• Orca spotting near Orcas Island offers unforgettable wildlife encounters with this private whale-watching tour.

3. Experience the Island’s History at the San Juan Island National Historical Park

San Juan Island National Historical Park tells a surprisingly intense story: the Pig War between the U.S. and Britain, sparked by—you guessed it—a pig. The park is split between American Camp on the south end and English Camp in the north, and each site offers scenic trails and preserved 19th-century buildings.

The visitor center at American Camp provides helpful context with displays and maps to guide your walk. I joined a ranger-led tour at English Camp and didn’t expect to be so fascinated by the history. You’ll learn about not just the military standoff, but also the Coast Salish tribes who originally inhabited the area.

There’s also great bird-watching along the bluff trails—bring binoculars if you’ve got them. It’s a peaceful way to explore the island and walk through a chapter of history that’s stranger than fiction.

4. Unwind Amidst Lavender Blooms at Pelindaba Lavender Farm

If you’re visiting in summer, don’t skip Pelindaba Lavender Farm on San Juan Island. This place is a total sensory reset—rows of purple blooms stretch toward the hills, and the air smells like relaxation itself. You can browse their lavender-based products like essential oils, body lotions, and even ice cream (the lavender vanilla scoop was surprisingly good).

I spent way too long here just walking the fields and trying the free samples. There’s also an on-site distillery where you can watch how they extract lavender oil, and seasonal workshops for things like wreath-making and cooking with lavender. Even if you’re not a plant person, this is one of those unexpected stops that sticks with you.

It’s peaceful, photogenic, and just feels wholesome. Whether you’re here for 20 minutes or two hours, it’s a great way to slow down and breathe in island life—literally.

5. Soar Above the Islands on a Scenic Flight

If you’ve never seen the San Juans from above, a scenic flight is the kind of experience that instantly shifts your perspective—literally. Flights usually depart from Friday Harbor or Orcas Island Airport, and in under an hour, you’ll loop over green islands, snowcapped mountains, and shimmering inlets.

Some operators like San Juan Airlines even let you customize your route. I did one of these flights on a whim after chatting with a couple at lunch, and it turned out to be the highlight of the trip. Watching Mount Baker, Mount Rainier, and the Olympics come into view all at once? Unreal.

If you’re into photography, bring your camera—it’s a goldmine of aerial shots. The planes are small, so every seat has a view, and the pilots are super knowledgeable. It’s not cheap, but it’s absolutely worth it for the memories.

6. Kayak Through the Bioluminescent Waters

Paddling through bioluminescent waters sounds like a fantasy, but in the San Juans, it’s the real deal. On dark summer nights near Friday Harbor or Roche Harbor, microscopic plankton light up with every paddle stroke.

Discovery Sea Kayaks and San Juan Outfitters run evening tours, and they’re super helpful—even if it’s your first time in a kayak. The first time I did it, I half expected it to be underwhelming, but the moment the water started glowing around us, I couldn’t stop laughing. It felt like something out of a sci-fi movie.

You’ll learn a bit about the science behind it too, which makes the whole thing even cooler. Just a heads-up—these tours fill up fast in peak season, so book early. If you’re after a truly one-of-a-kind island moment, this is it.

7. Explore Tide Pools at Cattle Point

Cattle Point, located on the southern tip of San Juan Island, is a favorite for low-tide adventures. Tide pools here are packed with colorful sea stars, crabs, and anemones, especially near the Cattle Point Lighthouse. Bring good shoes—the rocks can get slick—and plan your visit around low tide for the best viewing. Tide charts are your friend.

I came here one morning with coffee in hand and didn’t realize I’d spend nearly two hours crouched over rocks, totally absorbed. There’s something so peaceful about slowly discovering tiny creatures going about their day. It’s also a great spot for bird-watching—I saw oystercatchers and even a bald eagle overhead. If you’ve got kids or just love the ocean’s weird little details, this place delivers. Just remember to tread lightly—it’s an ecosystem, not a playground.

8. Hike the Trails of Mount Constitution

If you’re up for a good sweat and unbeatable views, head to Mount Constitution in Moran State Park on Orcas Island. It’s the highest point in the San Juans, and the 6.7-mile round-trip hike rewards you with a 360-degree view that stretches to Mount Baker, the Olympic Mountains, and even Canada.

The incline is steady but manageable, and there are benches along the way if you need a break. I took the trail early one morning, and the quiet was unreal—just birds, breeze, and the occasional chipmunk. At the top, there’s a historic stone observation tower where I ate a granola bar and soaked it all in.

If hiking isn’t your thing, you can also drive up, but the trek makes the summit feel way more satisfying. Either way, it’s a must-do if you’re visiting Orcas Island.

9. Sail the Waters with a Sunset Cruise

Few things top a sunset cruise in the San Juan Islands. Whether you’re celebrating something or just want a relaxing evening, watching the sun dip below the horizon from a boat is unforgettable.

I booked with Mystic Sea Charters out of Friday Harbor, and it was everything I hoped for—calm seas, glowing skies, and a low-key vibe with friendly crew members. Cruises often pass Lime Kiln Point, Stuart Island, or Shaw Island, depending on the route, and some include snacks or dinner.

I lucked out with clear skies and a pink-and-orange sunset that lit up the water. Bring layers—it gets chilly fast once the sun goes down. For couples, families, or solo travelers, this is a peaceful, memorable way to end a day. If you only splurge on one activity, absolutely make it this.

10. Stroll Through the Quaint Streets of Eastsound

Eastsound Village is the kind of place where you go for coffee and accidentally stay all afternoon. Located on Orcas Island, it’s packed with indie bookstores, local boutiques, and cozy cafés.

I stopped by Brown Bear Baking for a pastry and ended up talking to a local artist for nearly 45 minutes while browsing prints at Crow Valley Gallery. The town is small enough to walk but packed with personality. Highlights include Darvill’s Bookstore, the Orcas Island Historical Museum, and the Saturday farmers market in summer.

If you’re into food, don’t miss Hogstone’s Wood Oven for creative, wood-fired dishes. It’s also a good jumping-off point for kayaking or exploring nearby hiking trails. Even if you’re just killing time before your ferry, Eastsound makes it easy to slow down and enjoy island life.

11. Unwind at Doe Bay Hot Springs

Need a reset? Head to Doe Bay Hot Springs on Orcas Island for pure relaxation. The soaking tubs overlook Doe Bay, and the combo of hot water and salty ocean air is magic. It’s clothing-optional and adults-only, so expect a chill, respectful vibe. The spa also has a cedar sauna and offers massages if you’re really leaning into the whole self-care thing.

I stayed in one of their rustic cabins for a night and loved the quiet. After a long hike that morning, sitting in the tubs with a view of the water felt like the perfect ending. There’s also an on-site café serving seasonal, locally sourced meals, so you don’t have to leave if you don’t want to. Whether you book a day pass or stay overnight, Doe Bay is the spot to truly unplug.

12. Explore the Depths with Scuba Diving at Rosario Beach

Though technically not in the San Juan Islands, this top attraction on Fidalgo Island – just a short boat ride away – is definitely worth mentioning.

Rosario Beach in Deception Pass State Park is easily one of the most underrated adventures in the region. The visibility here often reaches 30 feet, making it ideal for scuba diving. Here, you’ll spot colorful rockfish, sea stars, and even the occasional octopus. Whether you’re just certified or a seasoned diver, the kelp forests and rocky reefs offer a lot to explore.

Local operators like Anacortes Diving can set you up with gear and guided dives. The shoreline also has tables and grills if you want to picnic before or after your dive. I came here on a random weekday and had the entire cove to myself. Swimming next to a curious harbor seal was an unexpected highlight.

If you’re up for something that combines calm waters with incredible biodiversity, diving Rosario is a no-brainer. It’s a refreshing break from the usual surface-level sightseeing.
