Coming back from the Mandala night club, you can either take the public bus or a cab. Make sure you have at least a dollar to get back. Always stay with your group of Friends too. This is especially true for you girls. Stay together. Do not come back by yourself. Mandala beach nightclub is very safe and secure, but why take a chance. If you have made some guy Friends at your hotel and they are with you, ask them if you can go back with them.Click for more info
