The trip Cartagena -Baru round trip must have been by boat that takes 40 or 45 min leaving the wharf the bodeguita or another dock because by land we take 1 hour and 30 minutes and from that time without 30 min on the trail with the possibility of getting stuck the small taxi-type car that I took us because there are puddles in that stretch with sand. We arrived in Baru very tired from the trip by land. It is not advisable to do that stretch by land. Everything else very good.

The food was amazing. Everyone was very nice. The girls there gave amazing massages. Definitely recommend and will be returning when I visit again.

Plancton is very worthwhile, the starry night contributes a lot. The transfer we took from Roundtrip left a lot to be desired. I recommend taking a lycra when taking the boat; the water is warm and comfortable.
