Why Osa Voyage
Local operator. Sierpe-based. No middlemen.
-
01
We launch from Sierpe, not San José
Your morning starts with a 5-minute walk to the Las Vegas dock — not a 4 a.m. shuttle. More wildlife time, less travel time.
-
02
ICT- and SINAC-certified guides
Bilingual, born here, trained for the terrain. Clear spotting protocols, real first-aid kits, and the patience to wait for the animals.
-
03
Small groups. Twelve guests, max.
Better viewing distance for the wildlife, more room for you. The boat is matched to the group, not the other way around.
-
04
Bilingual support, around the clock
Before, during, after. WhatsApp the owners directly for reschedules, weather questions, or a heads-up when you land in San José.

We did Sirena with Alex and it was a different thing entirely: he introduced us to the forest like family. Saw tapir, toucans and lots of birds.

Sierpe was the right call. Mangrove tour at sunrise was magical, and the family-style lunch after was the cherry on top. Booked Caño the next day.

Booked over WhatsApp in 10 minutes, paid online with no drama. Reached the dock and everything was ready. Would do it again.

Plan with us. Sleep tonight in Sierpe. Wake up in Corcovado.
