The weather is very hot and hummid in Bali. There are few things which I would pack in:
– Swimming suite
– One pair of long trousers for evening
– Hat or cap
– Flip flops
– Sneakers (good when you drive motorbike)
– Snorchel and diving goggles
– Beach towel
– Sun cream
– Backpack (good when you drive motorbike)
– Reduction (dat fotku zasuvek, které se zde pouzivaji)
If you like shopping do not take any clothes with you. You can buy it very cheaply in Bali. There are also lots of cheap laundry so no problem to wash it every day.
Actually you can buy everything in Bali, there are many shops, markets and shopping centres in big towns.
