Which outlying island in Hong Kong should I choose? Saigon's Hidden Jelly Sea

📍Detailed address: Geographical location: Sai Kung Half Moon Bay is located in the Sai Kung District of Hong Kong. It is named after its crescent-shaped bay. It is a treasure land far away from the hustle and bustle of the city. 🚉Transportation strategy: From downtown Hong Kong, take the MTR Kwun Tong Line to Choi Hung Station, walk from Exit C to Minibus Stop 1, and take a minibus directly to Sai Kung Pier. If you are departing from Guangzhou-Shenzhen, you can take the high-speed rail to Futian Station, then cross the border at Futian Port, then take the MTR to Shatin Station, and transfer to KMB bus No. 299 to Sai Kung Pier. The whole journey takes about 1 hour. After arriving at the pier, you can choose from the following two options: [One] Half Moon Bay One-way: Take a speedboat directly to Half Moon Bay (ferry ticket 40 HKD, 20 minutes), and enjoy the jelly sea and pristine beach; [Two] Half Moon Bay – Sharp Island Hiking Tour: Take a boat from Sai Kung Pier to Sharp Island (ferry ticket is about HK$30, 15 minutes), and walk through the "sea erosion channel" connecting the two islands (not accessible during high tide, need to confirm the tide time in advance). The whole journey takes about 1.5 hours, and you can get a close look at the volcanic rock landforms along the way. 👍Most Recommended: Geological wonders features: [Island] Half Moon Bay: The water is as clear as emerald, the beach is as fine as powder, the reef area on the northeast side is rocky, and the rocky beach on the southeast side is clear and calm. It is an excellent place for snorkeling and photography. [Mountain] Sharp Island Volcanic Rocks: The island is covered with breadstone and hexagonal columnar volcanic rocks. These are unique textures formed by erosion of volcanic relics 140 million years ago by sea water. [Purse] Ferry ticket cost: Sai Kung Pier → Half Moon Bay: HKD 40 (one way) Sai Kung Pier → Sharp Island: HK$30 (one way) ⏳Play time: You need to reserve at least 4 hours to visit both islands. The last boat leaves at about 17:30. It is recommended to confirm the schedule with the boatman in advance. ✅Must experience: Step on the "singing sand" in Half Moon Bay - the fine sand makes a gentle sound when rubbing against each other; touch the cool texture of volcanic rocks while hiking on Sharp Island and feel the geological story of billions of years; if you have enough time, you can overlook the panoramic view of Half Moon Bay from the "viewing platform" at the end of Sharp Island, where the blue sea and volcanic rocks form a magnificent picture. 📝Note tips: Some hiking sections require climbing rocks, so it is recommended to wear non-slip shoes; there is only a shop in Half Moon Bay on the island, so you can bring your own drinking water and light meals; pay attention to sun protection in summer and wind protection in autumn and winter. Tidal changes will affect the itinerary, so check the high and low tide times in advance. Sai Kung's Half Moon Bay and Sharp Island, one is a secluded jelly sea wonderland, the other is a natural museum carved by volcanoes and waves. Escape from the hustle and bustle of the city and come to this unexplored secret place, measure the natural epic with your feet, and gain the most primitive and gentle island memories of Hong Kong.
