Most people come to Oahu with a plan: sunscreen, a beach chair, and a cocktail in hand. And honestly, that’s not a bad plan. But if you’ve been to Hawaii before, or you’re the kind of traveler who wants more from a trip than a tan, you already know there’s another version of this island waiting for you.
The best adventurous things to do in Oahu don’t happen on a beach towel. They happen on the water. And that’s where we come in.
At Sea & Board Sports Hawaii, we run guided water sports and island adventure tours out of Haleiwa on the North Shore. Every tour we offer gives you a way to see Oahu that most visitors never get. So the question is: what kind of adventure are you after?
Stand Up Paddleboard Tours on the Anahulu River: The Best Way to See Sea Turtles in Oahu
If there’s one experience that defines what we do at Sea & Board Sports Hawaii, it’s our stand up paddleboard tour on the Anahulu River.
The Anahulu is the longest watercourse on the island of Oahu. It runs through the North Shore, and Hawaiian green sea turtles use it as a safe haven. They rest here between long ocean voyages, and you’ll often see them swimming alongside you or basking on the riverbanks in the warm Hawaiian sun. This isn’t a tank or an aquarium. These are wild turtles in their natural environment, and the Anahulu is one of the best places on the island to encounter them up close.
This is also one of the most accessible adventurous things to do in Oahu. You don’t need any paddleboarding experience. Our guides walk every guest through the basics on dry land before you ever step onto a board. The river is calm and the pace is relaxed, which makes this tour a genuine fit for all ages. Snorkeling is also available during the tour if you want to add an underwater layer to the experience.
What to Expect on Your Paddleboard Tour with Sea & Board Sports Hawaii
You’ll meet us at our Haleiwa location. From there, our guides take you through a land-based orientation before you head onto the river. All equipment is provided.
Our guides are lifeguard-certified with decades of experience between them. They keep the tour safe and low-pressure, and they know the river well enough to put you in the best spots for wildlife sightings. No experience is necessary. If you can stand up and hold a paddle, we’ll take care of the rest.
Glass Bottom Kayak Tours: See Oahu’s Underwater World Without Getting Wet
If you want marine life encounters from a different angle, our glass bottom kayak tour is the right call.
The kayaks we use have a clear hull. That means you paddle across the surface while watching
the ocean floor pass directly beneath you in real time. Fish, coral, sea turtles, whatever is down there, you get a direct view without entering the water. It’s a genuinely different way to experience the reef, and it’s one of the more unique adventurous things to do in Oahu for travelers who want wildlife and scenery but prefer to stay dry.
More Adventurous Things to Do in Oahu with Sea & Board Sports Hawaii
Paddleboarding and kayaking are our most popular water-based tours, but we offer a lot more. Here’s what else we have on the lineup.
North Shore Surf Lessons, Outrigger Canoeing, and Private Jeep Tours
Surf Lessons on the North Shore
Learning to surf on the North Shore of Oahu is one of those experiences that sticks with you. Our surf lessons are built for first-timers and beginners. We start on the sand, walk you through the mechanics, and then take you into the water with boards and rash guards provided. Each session runs 2 hours with lifeguard-certified instructors beside you the whole time.
Outrigger Canoe Tours
Outrigger canoeing is one of the oldest forms of ocean travel in the Pacific. Polynesian navigators used outriggers to cross the ocean between islands long before modern navigation tools existed. Today, outrigger paddling is experiencing a real resurgence in Hawaii as people connect with that cultural tradition.
Oahu Circle Island Jeep Tour
This is the full-day option. Our circle island Jeep tour is a private, 8-hour tour in a Jeep Gladiator, and it covers either the North and East Shore or the West Side of the island. You choose your route, and we build your day around you.
Stops can include surf lessons, paddleboarding on the Anahulu River, snorkeling at Shark’s Cove, a hike through Waimea Valley, Pipeline, Sunset Beach, Laie Point, local shrimp trucks, and more. The itinerary is fully customizable.
