Kayaking, Whale Watching, and Seaplanes: Exploring Washington’s San Juan Islands

Tucked between Washington State’s mainland and Vancouver Island, the San Juan Islands are a quiet slice of Pacific Northwest paradise. This archipelago—made up of over 170 islands, with four main ones accessible by ferry—feels a world away from the bustle of Seattle, even though it’s only a few hours’ journey. Think charming harbors, evergreen forests, driftwood-strewn beaches, and waters teeming with seals, porpoises, and even orcas.

Summer is the best time to visit the San Juan Islands. With long, sunny days, mild temperatures hovering around 70–75°F, and far less rainfall than the Seattle area, it’s perfect for outdoor adventures like sea kayaking, whale watching, and biking. On a calm July afternoon, the glassy waters of the San Juan Channel are ideal for a kayaking trip, offering a front-row seat to the islands’ incredible wildlife and coastal scenery.

When we visited last summer, we built our adventure around the water: flying into Seattle, taking a bus to Anacortes, catching the scenic ferry to Friday Harbor, and embarking on an unforgettable overnight kayaking tour of the San Juan Islands. We capped it off with a bucket-list seaplane flight back to Seattle—an experience I’ll never forget.

Why the San Juan Islands Are Perfect for Summer Adventures

The San Juan Islands are unlike anywhere else in Washington State. While the mainland often gets cloudy, drizzly weather, the islands sit in the “rain shadow” of the Olympic Mountains—meaning they enjoy significantly more sunny days than Seattle. From June through September, you can expect mild, dry weather, making summer the ideal season to explore these islands by land and water.

Outdoor adventure is what draws most visitors here, especially those eager to paddle the scenic San Juan Channel and surrounding waterways. With calm conditions, dramatic shorelines, and a rich variety of wildlife, this area offers some of the best kayaking experiences in Washington State. Summer is also the prime season for kayak tours in the San Juan Islands, where you might spot harbor seals lounging on rocky outcrops, bald eagles soaring overhead, or even an orca pod gliding by on a lucky day.

Beyond kayaking, the islands invite you to slow down and savor the simple joys of island life—think whale-watching cruises, biking quiet coastal roads, and ending the day with a breathtaking sunset over the Salish Sea. It’s the perfect mix of adventure and relaxation.

How to Get to the San Juan Islands from Seattle

One of the things I love about visiting the San Juan Islands is that the journey itself feels like part of the adventure. Getting there requires a combination of transportation—bus, car, ferry, or even a seaplane—each offering its own scenic experience.

Since we flew into SEA-TAC Airport, we opted for a no-stress approach and booked a ride on the Bellair Airporter Shuttle. This bus service is incredibly convenient, with multiple stops as it makes its way north to Anacortes, home of the Washington State Ferry terminal. It was the perfect way to relax after our flight and avoid the hassle of renting a car or finding parking at the terminal.

The ferry ride from Anacortes to Friday Harbor takes about an hour, and it’s as much a sightseeing cruise as it is transportation. You’ll glide past tree-lined islands, spot seabirds, and maybe even catch a glimpse of a harbor seal or porpoise in the distance. We couldn’t help but feel like our adventure had already begun before we even set foot on San Juan Island.

For travelers bringing their own gear, kayaks can be transported on the ferry, though most visitors choose guided kayak tours in the San Juan Islands to simplify logistics. Whether you’re planning a day paddle or a multi-day kayak trip, starting your journey with a ferry ride is part of the quintessential San Juan experience.

Exploring Friday Harbor Before Your Kayak Tour

Friday Harbor is the heart of San Juan Island and the hub for travelers heading out on kayak tours in the San Juan Islands. It’s the first stop for most visitors arriving by ferry, and it’s the kind of place that instantly puts you in “island time” mode. Colorful storefronts, waterfront restaurants, and views of the harbor filled with sailboats make this little town worth exploring, even if you’re just passing through.

We stayed at the Discovery Inn, a quiet property located about a mile uphill from downtown. The staff were incredibly friendly, and they even let us store our extra luggage overnight while we were out on our kayaking trip—a lifesaver when traveling light on the water. One note: if you’re traveling without a car, be aware that the walk is uphill and can feel long with luggage in tow, so a quick cab ride might be worth it.

On either side of our kayak adventure, we ate out in Friday Harbor and loved the variety of restaurants offering deck seating with harbor views. Watching the sun set over the water while enjoying fresh seafood (or a cocktail) was the perfect way to wind down after a day of exploring. There’s no shortage of great options in town, from casual cafes to more upscale dining with panoramic views of the harbor.

Our Overnight Sea Kayaking Trip

The highlight of our San Juan Islands getaway was, without a doubt, our overnight sea kayaking tour with Sea Quest Kayak Tours. They offer a wide range of guided kayaking tours in the San Juan Islands—from quick half-day outings to multi-day adventures—but we chose their all-women’s overnight trip, which was the perfect mix of adventure, camaraderie, and relaxation.

Over the course of two days, we paddled about seven miles each day, gliding across calm waters with the evergreen-lined islands all around us. Our first day included a lunch stop at Turn Island Marine State Park, a tiny, rocky island known for its seals and seabirds. By late afternoon, we reached Jones Island Marine State Park, our home for the night.

Our campsite was perched right on the water’s edge, offering an unobstructed view of the sunset—and what a sunset it was! While we unwound at camp, our guide handled everything, cooking a hearty hot dinner and, the next morning, a delicious breakfast. It felt like a luxury to simply relax and take in the scenery while someone else took care of the logistics.

Jones Island’s amenities surprised us too; with a fresh water spigot and a pit toilet, it wasn’t a totally primitive experience—perfect for those dipping their toes into San Juan Islands sea kayaking for beginners. Along the way, we spotted countless bald eagles perched in the trees, curious harbor seals sunbathing on rocks, and plenty of other sea life. While we didn’t catch a glimpse of an orca this time, the anticipation of spotting one made every paddle stroke that much more exciting.

It’s worth noting that sea kayaking in the San Juan Islands is not like paddling on a calm lake. The water is cold year-round, typically hovering around 50–55°F, and currents can shift quickly with tides and wind. Unless you have experience with open-water or sea kayaking, I highly recommend booking a guided kayak tour. Companies like Sea Quest know how to safely navigate the San Juan Channel and choose routes based on weather, tides, and wildlife activity. Having a guide not only makes the experience safer but also more enjoyable—they’ll point out wildlife you might miss and handle all the details, so you can simply paddle and take it all in.

Flying Back to Seattle on a Seaplane

After our kayaking adventure, we decided to end our trip in style by flying back to Seattle on a Friday Harbor Seaplanes flight. While this option is pricier than the bus-and-ferry route, it’s absolutely worth it if your budget allows—it’s not just transportation, it’s an experience in itself.

From the moment you take off, the views are breathtaking. The plane skims across the water before soaring above the emerald-green islands, offering a bird’s-eye perspective of the San Juan Channel, forested shorelines, and sparkling blue inlets below. We could even spot a few ferry boats making their way through the archipelago, tiny compared to the wide-open waters. On a clear day, you can see Mount Baker, the Olympic Mountains, and even the Seattle skyline coming into view as you approach the city.

The entire trip from Friday Harbor to Seattle takes less than an hour—compared to the half-day it takes via bus and ferry—making it a huge time saver if you’re short on time or want to squeeze in extra adventures before heading home. Friday Harbor Seaplanes also makes the experience seamless, with convenient departure times and friendly pilots who know the islands well. It’s a splurge, but one I would happily make again.

What to Pack for Your San Juan Islands Kayaking Trip

Packing for an overnight sea kayaking trip in the San Juan Islands requires a bit of strategy—everything you bring has to fit inside the kayak’s storage hatches, which means packing light and keeping everything dry. Most outfitters, like Sea Quest, will provide the big gear (kayak, paddles, and PFDs), but your personal items need to be packed carefully.

Here’s what to keep in mind:

• Dry bags are essential. Everything—clothes, sleeping bag, toiletries—needs to fit in these waterproof bags. You can often rent them from your outfitter, but I brought my own, which worked perfectly. Pro tip: Label your dry bags because they all look the same when unloaded on the beach!
• Quick-dry, layered clothing. Bring lightweight layers that can handle getting damp (avoid cotton). Include a warm layer for cool nights.
• Sleeping gear. If not provided, pack a compact sleeping bag and a small travel pillow.
• Footwear that can handle mud and water. My water shoes were trashed after the trip because the mud was so stubborn—it’s worth choosing shoes that can be tossed in the washer or easily hosed off.
• Sun and water protection. Sunglasses with a strap, reef-safe sunscreen, a wide-brim hat, and lip balm with SPF.
• Waterproof phone case or GoPro. I highly recommend bringing something like a GoPro or a waterproof phone pouch for wide-angle shots and peace of mind.
• Reusable water bottle and snacks. Staying hydrated is key when you’re paddling several miles each day.

For an overnight tour, the outfitters typically pack group gear (like cooking supplies and food) separately, so your personal load is surprisingly light—but being organized makes the experience so much smoother.

Other Outdoor Adventures in the San Juan Islands

While kayaking in the San Juan Islands is the highlight for many visitors, there’s no shortage of other ways to enjoy these islands if you have extra time.

• Whale Watching: The San Juans are one of the best places in the world to see orcas in the wild. A dedicated whale watching tour offers a near-guaranteed chance to see these majestic creatures, along with humpback and minke whales during the summer months.
  
• Biking and Hiking: Lopez Island is known for its quiet roads and gentle terrain, making it a cyclist’s paradise. For hiking, head to Lime Kiln Point State Park on San Juan Island, famous for its lighthouse and shoreline whale-watching. Over on Orcas Island, Moran State Park offers scenic hikes, including a trek to the top of Mount Constitution for sweeping views of the islands.
  
• Scenic Drives and Beaches: If you have a car, exploring the island by road is a treat. Pull over at scenic overlooks or visit hidden beaches like South Beach in American Camp, where you can enjoy long stretches of driftwood-strewn shoreline.
  
• Island Hopping: With ferries connecting the main islands—San Juan, Orcas, Lopez, and Shaw—you can spend a day exploring a different island vibe, each with its own unique character.
