Here my budget trip at Labuan Bajo. It takes one day, starting when sun rises till it goes down. The trip went to :
Padar Island
Pink Beach
Lost Beach
Taka Makassar
Turtle Hunting
Manta Point

Speedboat by @alexandriacruise_lbj (instagram)

Better to make reservation day-1 directly at their office, to prevent any scheme from irresponsible person!

Super worth it!!
