Here’s about Tuba Island.
Pulau Tuba is the only inhabited island besides the main island of Langkawi itself. This Langkawi island gets its name from the tuba roots. It is the only other island that offers accommodation and there are a few places to stay. If we're not mistaken, there is a resort there called Sunrise Beach Resort. We recommend you to try Tok Janggut's chalet on Pulau Tuba. The owner of the chalet charges RM30 per person and that includes 3 meals a day plus accommodation.
At Pulau Tuba, you can also experience traditional fishing village life with fishermen returning home in the evenings in their quaint fishing boats. Pulau Tuba offers a homestay program organized by fisheries development Authority of Malaysia as an innovative tourism products. You may want to try this out - it's an opportunity to personally experience the lifestyle of the islanders.
There are 30 houses registered under this program and all of the household head works as a fishermen. Apart from fishing they do some farming, raring animals like chicken/cows/water buffalo/goats and mend their orchard. Occasionally the islanders go into the jungle to collect forest product including herbs, medicinal roots, honey bees and wild fruits. The woman folks weave pandan mat and making other handicraft products to supplement their family income.
