Flores -- 1 Day Snorkeling

I think apart from seeing the komodo dragons, my other favorite was the 1-Day snorkeling trip.

NorthWest Bali: West Bali National Park and Menjangan Island

A quick day trip anyone can do is go up North-West Bali and explore the little but beautiful towns on the coast like Banyuwedang, Pemuteran, and all the way to Lovina and Singaraja.

Flores -- Rinca + Kanawa Day Tour

There are two island you can visit to see the famous Komodo Dragons. One is Komodo Island and the other, RInca. 

People will have various opinions on which island is better. After researching and asking around extensively, I realized, it all depends on you and your schedule.
