We had a great two weeks in North Sumatra and West Sumatra having spent time in Bukit Lawang, Brastagi, Toba Lake, Bukitinggi and surrounds, Harau Valley and Maninjau Lake. Me and my wife and our little dougther. The two weeks spent with Al Dava as our guide were fantastic. Al is a knowledgeable, humorous and flexible guide who went out of his way to give us a great trip. It's clear he's rightly proud of some aspects of Batak and Minangkabau history and culture, but also has really interesting and have knowledge about nature and wildlife and plants. He was able to come and get us a day early and rearrange our program at the last minute and made each day interesting and relaxing for us. He's a great guide and have good driver too- meaning we could enjoy the hours on the road knowing we were in safe hands. Thank so much to let us know about Indonesia foods, nature , wildlife, culture and tradition. Overall we highly recommend Al Dava and i will tell to friends and family if they want make a trip in Sumatra. We suggest go with Al Tom & Rachel and your naughty niece ;) Laura
