The Blue Ocean Tide-Catching activity is located on the resource-rich Mangrove Beach. The main inhabitants of the mangroves are marine mollusks, including common species such as sieve-eyed clams, broken kings, comb pen shells, rough bird clams, horse hoof snails, phoenix snails, granular fruit snails, and several types of hermit crabs. Visitors can pass through the mangroves to the tide-catching spot and fully enjoy the pleasure of digging for snails, sand crabs, bamboo node snails, and sandworms. The activity is open all year round from 06:00 to 23:00.
