Along with Manukan Island—the second-largest and best-developed island in the marine park—Sapi Island (Pulau Sapi) is on the itinerary of most island-hopping tours of Tunku Abdul Rahman Marine Park from Kota Kinabalu. Tours typically include round-trip transfers by boat and bus, and give you free time to swim, snorkel, and hike on between two and four of the islands. Some tours also include a ride on the Coral Flyer Zipline, which connects the islands of Sapi and Gaya.
The only way to reach Sapi Island (Pulau Sapi) is from Jesselton Port, located just off the waterfront promenade in Kota Kinabalu. Motorized boats are operated by several different companies and depart regularly from the early morning. The journey takes approximately 20 minutes.
From Jesselton Port, the last boat departs for Sapi Island just after lunchtime; all boats return to the port in Kota Kinabalu at around 4pm. Sapi Island is most crowded during peak season, which spans the months of June, July, and August.
Tunku Abdul Rahman Marine Park is comprised of five islands, which include Sapi, Gaya, Manukan, Sulug, and Mamutik. Manukan Island is the most developed and popular of the five; its 1-mile (1.5-kilometer) beach is lapped by the calm waters of the South China Sea, which are ideal for swimming and snorkeling. Plus, there’s the highest concentration of restaurants and watersports opportunities on the island.
