My spending habits collapsed after 3 days in Beihai...

Practical guide: ✅ Must-see attractions: - Alligator Mountain Scenic Area: Volcano Crater Geological Park (ticket price: CNY 98), with a new "Volcano Night Tour" (19:00–21:00), where lights outline the lava contours. - Muya Sunset: Unnamed cliff on the west side of Shiluokou (locate "Zitongmu Village Fishing Boat Anchorage"), less crowded with beautiful scenery. - Shengtang Catholic Church: A century-old French building where sunlight penetrates the rose windows during the French Mass at 8:30 am on Sundays. ✅ Featured experiences: - Beachcombing: During the spring tide in May (e.g., May 2) from 02:00–13:00, dig for snails and catch crabs in the mangrove area (tool rental + guide: CNY 50/person). - Xieyang Island hopping: Ecological island tour (ferry ticket: CNY 150), hike for 2 hrs to see the volcanic Tianchi Lake. Hiking shoes are required. ✅ Food recommendations: - Nanwan Street: Apo Seafood Stall (salt and pepper mantis shrimp + scallops, CNY 60/person). - Dishui Danping: Fishermen's sun-dried fish (CNY 10/bag), can be used as a gift. ✅ Accommodation recommendations: - Dishui Danping: Yeshu Homestay (sea view terrace, 3-min walk to the beach). - Shiluokou: Qingli Hotel (popular swimming pool + snorkeling equipment rental). ✅ Transportation tips: - Take a boat from Beihai International Passenger Port to Weizhou Island (fast boat: CNY 150/1.5 hrs, buy tickets 3 days in advance). - Rent an electric bike on the island (CNY 50/day). The "Aima" brand is recommended for its long battery life.
