The Perhentian Islands (Pulau Perhentian in Bahasa Malaysia) lie approximately 10 nautical miles (19 km) offshore the coast of northeastern Malaysia in the state of Terengganu, approximately 40 miles (64 km) south of the Thai border. The two main islands are Perhentian Besar (“Big Perhentian”) and Perhentian Kecil (“Small Perhentian”). Popular for it’s beaches, snorkeling and driving. Like a real postcard.
Langkawi is an archipelago of 99 islands in the Andaman Sea, some 30 km off the mainland coast of northwestern Malaysia. The islands are a part of Malaysia’s Kedah state, but are adjacent to the Thai border. By far the largest of the islands is the eponymous Pulau Langkawi with a population of about 45,000. The island is a declared duty-free zone.
The peak season is from December to March when moonson at the eastcoast shuts down most of the Islands there (Perhentian etc.). This makes Langkawi a good island alternative during that time period. Generally though, Langkawi can be visited all year around.
