Introducing Tunku Abdul Rahman National Park
Whenever one enjoys a sunset off KK, the view tends to be improved by the five jungly humps of Manukan, Gaya, Sapi, Mamutik and Sulug islands. These swaths of sand, plus the reefs and cerulean waters in between them, make up Tunku Abdul Rahman National Park, covering a total area of just over 49 sq km (two-thirds of which is water). Only a short boat ride from KK, the islands are individually quite pretty, but in an effort to accommodate the ever-increasing tourist flow (especially large numbers of Chinese), barbeque stalls and restaurants now crowd the beaches. On weekends the islands can get very crowded, but on weekdays you can find some serenity. Accommodation tends to be expensive, but most travellers come here for day trips anyway, and there are camping options.
Although it's no Sipadan, diving in the park is a popular activity, and the area is considered a good spot for getting open water certified. Borneo Dream and Downbelow both run diving programs on Pulau Gaya.
