Malaysia and Aceh are both sharia so if you like that you will be fine. http://www.aceh-kite(remove this stupid seabreeze filter)camp.com/ seabreeze(remove this stupid seabreeze filter)kiteclub.com/aceh-indonesia/ you should be able to send an email to one of these guys to find out what the wind is doing. You should be able to get a flight thru Medan to Aceh. traveloka.com is great for booking flights in Indo. Otherwise you could try Lakey Peak in Sumbawa get a flight thru Bali to Bima.

Spent 6 weeks north sumatara last year, fly to medan then go to bukit lawang and see orang utans, awesome spot and cheap to stay but treks pricey. Also then go onto lake toba as part of the drive, well worth it. If u want surf then Nias island is a one hour $100 flight, 3 n 4 days for transfer food and accomodation down south (indicators) for $350

orangutangs would be nice.

Yeah as cisco says a lot of care to be taken, visa under one month same as bali so just on entry, have some good contacts if u need pm me
