Boat Trips -- The Río Sarapiquí was originally this region’s, if not the country’s, major transportation thoroughfare, connecting the town of Puerto Viejo with the Caribbean coast. For the adventurous, Puerto Viejo is a jumping-off point for trips down the Río Sarapiquí to Barra del Colorado National Wildlife Refuge and Tortuguero National Park on the Caribbean coast. A boat transfer for up to 10 people will cost you around $400 to $600 to Barra del Colorado or $500 to $700 to Tortuguero.

In addition to the longer trips, you can take shorter trips on the river for between $15 and $25 per person per hour. A trip down the Sarapiquí, even if it’s for only an hour or two, provides opportunities to spot crocodiles, caimans, monkeys, sloths, and dozens of bird species.

If you’re interested in any of the boat trips on the river, you are best off checking at your hotel, or with Oasis Nature Tours ((tel) 2766-6108; Alternatively, you can head down to the town dock on the bank of the Sarapiquí and see if you can arrange a boat trip on your own by tagging along with another group or better yet, with a bunch of locals.
