If you only have half a day, Rangko Cave is the best use of it. The cave lies on the coast a short boat ride from the Labuan Bajo harbor, and its main chamber holds a pool of clear water lit from above, where swimming is the draw. This half-day trip shares a boat with other travelers, visits the cave and then moves to a beach for snorkeling over a reef close to shore. The format is simple and low-cost, with no long drives and no overnight commitment. It suits the first or last day of a trip, a day when the weather is not right for the big islands, or any traveler who wants a taste of the area at a modest price.
At the cave, you step off the boat and walk down a short set of steps to the pool. The chamber is not large, and a busy period means taking turns for photographs, so an early or late slot is more peaceful. Swim carefully, since the rock is wet and the floor is uneven, and use a life vest if you are not at ease in the water.
The snorkeling stop that follows is typically at a nearby beach or reef where the water is shallow and the fish are plentiful. Conditions depend on tide and wind, so visibility varies. Reef-safe sunscreen and a rash vest protect you and the corals, and a mask that fits matters more than any other gear.
Because the trip is short, it fits around other plans, but check the departure time and where to meet. Bring a towel, a change of clothes, a little cash and a dry bag, and ask whether snorkel gear and drinking water are included.
