Yo Island is a popular day trip from either Hat Yai or Songkhla. The island has become especially popular since a bridge linking the north and south sides of the lake was built in 1984. At 2.6 kilometers (1.5 miles) long, its Thailand's longest span.
The main sight on the island is the Southern Folklore Museum on the northern tip of the island. The museum's goal is to preserve the unique culture of the south. The exhibits include houses, fabrics, pottery and other traditional arts. The museum is open every day from 8:30 a.m. to 5:00 p.m. Admission is 50 Baht.
The island is popular with shoppers, who like the rich cotton fabric produced on the island, as well as a wide variety of seafood products. Naturally, there are plenty of seafood restaurants to have an enjoyable lunch in during your trip.
