Respect the Locals
The Indonesian local surfers will be your new best friends. If you treat them with respect you will enjoy your trip so much more. A smile is worth a thousand words in any language.
If you smile, talk quietly and give them the respect they deserve, you will develop true friendships, get cheaper bargains as a bonus, but more importantly you will gain a genuine insight into their uniquely spiritual lives and centuries old cultures. Indonesia is alive with religions like Islam, Hinduism, Buddhism, Christianity and ancient Animistic beliefs. Your spirit will come alive in Indonesia.
