“Take a Ferry From Bali to Komodo Island
Before you go getting all excited at a drastically cheaper option, just know that the ferries take an extremely long time (36 hours) to get there, and it’s not exactly comfortable for that long of a ride. OH, and it’s dangerous. I’m serious. If you’re scared to fly in small planes, you have a lot more to worry about on a ship that sails over shallow, rocky waters. Just saying.
The route from Bali to Komodo Island is said to be seriously hard to navigate, but it’s also said to be quite the adventure. Either way, I would prefer it if no one died before they got to see the Komodo Dragons, so maybe opt for the flight if you can.
