I am sorry if this is a question that has been posted a million times, but I am currently living in a small village on Java with very little internet so I don't have a lot of time to check through the forum, apologies :)
I will be flying into Medan December 20th and flying back into Bandung on January 4th. Currently on my wish list for my roughly 14 days in Sumatra is a bit of jungle trekking, hanging out on Lake Toba, and doing some snorkeling/kayaking/hanging out on the Banyak islands. I do not really mind in what order that happens but it seems the easiest route to take would be to head straight from Medan to Bukit Lawang, then to Lake Toba, then out to the Banyak Islands, and back to Medan. Does it make sense to do it in this order? How easy or difficult is it travel between these locations using public transportation?
Also, my friend and I are currently volunteering in Indonesia with the Peace Corps, and thus we don't have a ton of money to spend. We are looking at budget options for transport and sleeping. Likewise, if anyone has suggestions for a reasonably priced guide for trekking or for kayaking in the Banyaks, I would love to year it! Does anybody have a favorite island to visit? I am not a surfer, I prefer calm waters with good snorkeling and easy swimming if that sounds like any islands you know :)
Thank you so much for any information you can provide. Again, I am sorry if this information has already been posted.
