Is it realistic to fly from Singapore to Medan, and then make my way down to Bukit Lawang for Gunung Leuser and Orangutans.
Then how do I get from there to Beristagi for Lake Toba? Please don't say back to Medan first...
Then from Lake Toba area, I want to get down to Bander Lampung direction and hop over the java sea to Krakatoa island to see the volcano there - before continuing my Indonesia odyssey across Java and into Bali and then back up to Suluwesi.
Are these Sumatra plans realistic?
