Basalt Island Attractions: Sea Arch: “Kwan To Arch” Sea Cave: “Basalt Secret Cave” Hexagonal Columns: everywhere Diving/Snorkeling: “Sea Dragon Palace” Sai Kung Public Pier has many speedboats you can hire for an agreed-upon pick-up and drop-off time. It takes about 30 minutes to travel to Basalt Island by boat. You can request to be dropped off at the pebble beach on the northern side, closest to Sai Kung. Boats are also able to drop you off directly in front of the Sea Palace or Kwan to Arch, the famous archway of Basalt Island. A waterproof bag big enough to carry your belongings as you swim is necessary. If you are not a strong swimmer, it is recommended to bring some type of floatation device (or a waterproof bag that can be inflated) or a life vest, as the waves can get a bit rough around the island edge. ⚠️Do not visit shortly before or after a typhoon or on days when easterlies persist.
