Golf
Oahu as a whole has 39 golf courses, but many are private, or for military personnel. The municipal courses closest to Waikiki are the Ko'Olau, New Ewa Beach and Luana Hills Golf Clubs.

Parks
Waikiki for its size has much open parkland including Kapiolani Park, Ala Moana Park and Diamond Head National Park. The parks provide a quiet and relaxing environment, especially beneath a shady tree on a hot day.

Diving & Snorkelling
There's reef snorkelling and diving off the main beach in Waikiki, also at Hanauma Bay (see Sightseeing) and further west at Ko'olina. Equipment is easily available to hire and many hotels have scuba lessons available. Night dives are also popular amongst more experienced divers.

Sailing & Windsurfing
The Yacht Harbor at Waikiki offers sailing excursions and yacht hire, subject to experience. Diamond Head Beach is the most popular windsurfing venue, or alternatively try North Shore across the Island.

Surfing
Hawaii was made famous for surfing by Duke Kahanamoku, often called 'the father of surfing' and you'll see tributes to him throughout Waikiki, including Duke's Bar at the Outrigger Waikiki. Diamond Head Beach and North Shore are the most popular places to surf. You can also get lessons at Dukes Surf Academy.

Submarine Excursions
A number of companies now run mini-sub excursions around the reefs surrounding Waikiki. Most of these operate from the pier at the Hilton Hawaiian Village.

Walking & Hiking
The parks and mountains around Waikiki offer leisurely and challenging walks and hikes. Diamond Head National Park is a good place to start with stunning views available from atop the volcano.

Whale Watching
This is seasonal, usually from mid-November through to early March. It usually pays to take an offshore trip, though whales are visible from shore, mostly with binoculars. Kaena Point and North Shore on the west of the island offer the best vantage points for viewing with the naked eye.
