Pulau Kapas is a small island located only about 6km off Marang in the east coast state of Terengganu (about 1h north of Kuala Terengganu). It has quite and relaxed atmosphere because it is bypassed by the majority of the backpacker circuit looking for a more remote place like the Perhentian Islands. Pulau Kapas only get fairly busy on the weekends when locals come to island. There are a few good snorkeling spots around the island. All accommodations and beach are on the west coast facing the mainland. The west coast is the weather side has no sand beach, only rocks - it can be reached after a short walk through the jungle. Pulau Kapas shuts down during the monsoon season between November and February.
Johor Bahru is the state capital of the state of Johor and the second largest metropolitan area in Malaysia. Most tourists don't stop here and just pass through the city on their way to or out of Singapore. JB is a major local transportation hub however. Since it is just across the causeway from Singapore, some travellers use it as a hub to visit Singapore from here (lower accommodation prices) or to board the train, bus or airplane.
