You plan to fly from Bali to Flores? It’ll probably take several days overland.
When I did it we had to transfer from the big ferry which runs between the big islands to the little boat from Komodo on the open sea.
I don’t know about today, but ten years ago Komodo Island was as unspoilt as you could hope for and the reefs were gorgeous. No diving facilities though, but that has probably changed. It was a national park with only one place to stay - rotting wooden cabins on stilts, no electricity after 9pm, rats in the rafters. Komodo dragons wander through the facility, and the day I arrived there was a deer grazing about ten feet away from a sleeping 4m lizard.
At that time they had stopped doing the live goat feeding show as it discouraged the dragons from hunting. We took a hike and saw numerous piles of sleeping dragons. This is pretty much all they do, and there was a TV crew there who had spent two weeks waiting for something interesting to happen.
Beaten track, forest, silence, no sign of civilisation except for the helicopter pad that was rarely used. Oh, and we saw two Komodo Dragons tear a live deer to pieces after rounding a bend in the path to find it held firmly by a set of strong teeth around its neck. Sadly, the TV crew weren’t with us. Apparently this is a really rare thing to witness.
Flores was interesting. I remember an excellent day tour conducted by a guy named Lucas which included undeveloped hot springs on the slope of a volcano and dinner in his village, which was on of those places you could believe was created just to impress tourists if there had been more tourists. Can’t remember the name of the place though.
Keli Mutu was worth getting up early for, and we walked down the mountain afterwards and finished up having a swim in a waterfall. We stumbled into a house where a lady tried to sell us some of the Ikat weaving she was working on, for a tenth the price you’ll see it for in Kuta. Also, I remember meeting people who were walking up the mountain on dirt trails to church, dressed in their Sunday best (still barefoot) and with their bibles balanced on their heads.
You could spend a week on Flores without difficulty.
