Sharp Island is a popular day trip location for swimming, snorkeling and island exploring. It is located in the Port Shelter, just a couple of kilometres from Sai Kung Village and is accessible by way of regular sampan and kaito boat transportation from the Sai Kung New Ferry Pier (9am to 6pm daily). Tickets can be purchased from the various operators that line the promenade to the main Sharp Island pier (HK$30 round trip) on the north end of the island or the Hap Mun (Half Moon) Bay pier (HK$40 round trip) in the south.
The island includes two main beaches, Kiu Tsui Beach in the north and the very popular Hap Mun Beach down south. This second beach is noted for the fine quality of sand, very clean waters and beautiful scenery. Both beaches have expected facilities including showers, changing rooms, lockers, lifeguards and kiosks. Do note that during the pandemic, these facilities, like all other beaches around Hong Kong are closed.
Another island attraction is the UNESCO Geo Trail found near the main ferry pier. Here visitors can walk a nearly 500 metre trail that crosses a tombolo (land bridge) to a tiny adjacent island. The tombolo is accessible during most of the day but slightly under water during the height of high tides (>1.4 metres).
Along the tombolo and the adjacent small island there are interesting geological features which date back 140 million years when the entire area of Sai Kung was believed to be part of a super volcano. Most interesting are the quartz monzonite, locally referred to as the 'pineapple bun' rocks given their resemblance to this important and popular local food speciality.
There is a nice trail between Kiu Tsui and Hap Mun that is around 1.6 km in distance. The trail crosses from north to south, covering attractive island landscape, climbing to an elevation of around 135 metres above sea level. What makes the trail nice is that it follows a ridge much of the way, providing views of the coastline, the sea as well as other outlying islands on both sides of Sharp Island. When sky conditions are favourable, the views are really nice in both directions.
At the south end of the island, there is a boulder beach that you can explore a bit but be ready for proper coasteering the further you go south as it because rather challenging the further you go. Near the southern tip of the island there is a popular sea cave but given the difficulty navigating on foot, this is mostly a place visited by those with kayaks.
You will notice, particularly on weekends and public holidays, quite a few people camping at both ends of the island, taking advantage of the public facilities found at the two beaches. There are a few BBQ pits and tables as well. The public beach facilities include simple kiosks for food and drink purchases. However, best to bring your own drinks & snacks that you can purchase back in Sai Kung before making your way to the island.
