You have to check the domestic flight schedule between Tarakan and Manado if there is any service at all.Best way to include Sangalaki is to head to Manado right after. So we'll have to do it around end of Nov. Which is good for Sipadan, so hopefully also good for Sangalaki.
We don't have to dive in Green Island. But first thing Taiwan reopens, I'm taking my kid and grandma there. My two college best friends haven't been and want to go too, and one of them is my dive buddy on this big trip. There is the most beautiful hot spring in the world on Green Island and tbh I'm only diving its frigid water (for my standard) as an excuse to spend the entire evening in all the different pools of the hot spring. Hoping to explore Orchid Island this time, maybe also checking out Taitung, otherwise just returning to Taipei, Keelung, and Taroko Gorge I think. Not extremely keen on the Westcoast cities.
There is nothing in Taitung for tourist. Not going to Alishan?
Water in Green Island is not cold in June.
The West coast is far more interesting than the East(my experience).
Do you know there is a Southern branch of the National Palace Museum outside Chiayi?
