Paddle 1.5 miles from Kailua Beach to the twin Mokulua Islands seabird sanctuary, snorkel in the turquoise waters, and explore sea caves along the coast.
Kailua Beach on the windward coast of Oahu is consistently ranked among the finest beaches in the United States, and the paddle route to the twin Mokulua Islands seabird sanctuary — known locally as The Mokes — represents one of the most rewarding half-day water adventures accessible from the Honolulu metro area. The crossing covers approximately 1.5 miles from Kailua Beach Park through shallow turquoise reef flats and open water, with the dramatic Ko'olau mountain range forming a vivid backdrop to the west.
The Mokulua Islands are a state seabird sanctuary managed by the Hawaii Division of Forestry and Wildlife. Landings are permitted only on Moku Nui, the larger island. A short trail leads to an overlook above a dramatic blowhole and a sheltered cove informally called Shark's Cove, named for its tooth-shaped outline rather than any shark presence. Green sea turtles are frequently encountered near the reef channels surrounding both islands, and wedge-tailed shearwaters nest in burrows on Moku Iki during summer months.
Guided tours and standalone kayak rentals are available at Kailua Beach Park from operators including Kailua Beach Adventures and Twogood Kayaks Hawaii. Rentals include a sit-on-top kayak, double paddle, personal flotation device, and a dry bag, along with a navigation briefing for self-guided paddlers. Guided tours add an experienced naturalist leader who provides context on reef ecology, seabird biology, and island history. All participants receive a safety briefing covering paddling technique, capsize recovery, and marine park regulations.
The crossing requires moderate paddling fitness and the ability to handle a sit-on-top kayak in open water with trade-wind chop. Trade winds on Oahu's windward coast typically build from mid-morning, making early departures before 9 a.m. strongly advisable for beginners. The return leg paddled into the wind is significantly harder than the outbound crossing. Snorkeling gear can be rented at the beach to explore the reef around the Mokes. The full roundtrip, including time ashore on Moku Nui, typically runs three to four hours.

When to visit
Year-round; mornings from May through September offer the calmest conditions. Early morning departures before trade winds strengthen provide the easiest crossing and the clearest water colour.
Accessibility
Kailua Beach Park has paved parking and restroom facilities near the launch area. Kayak launches require carrying equipment across beach sand and entering shallow water. The activity is not accessible for wheelchair users or individuals with significant upper-body limitations. Sit-on-top kayaks require boarding from shallow water, which may be feasible for some ambulatory participants with assistance.
Frequently asked questions
Do I need kayaking experience to paddle to the Mokulua Islands?
No formal training is required for the guided tour, where operators provide a safety and technique briefing at the beach. Self-guided rentals require more confidence in open water; beginners are better served by a guided tour.
Can I snorkel around the Mokulua Islands?
Yes. Snorkeling gear can be rented from beach operators and the reef surrounding both islands is excellent. Landings are permitted only on Moku Nui; Moku Iki is a restricted seabird sanctuary where shore access is not allowed.
How long does the paddle to the Mokes take?
The crossing from Kailua Beach to Moku Nui is approximately 1.5 miles and takes 20 to 40 minutes depending on wind conditions and paddling fitness. Afternoon trade winds significantly lengthen the crossing time.
What is the best time of day to go?
Early morning before 9 a.m. provides the calmest conditions. Afternoons see stronger trade winds that make the return crossing substantially harder, especially for beginner paddlers.
Is the trip suitable for children?
Children who can swim and are comfortable in open water are generally suitable participants. Most operators accept children from around age five or six in tandem kayaks with an adult. Personal flotation devices are always provided.
