Crocodile boat tours on the Río Tárcoles are this small town's claim to fame. You don't actually have to drive to Tárcoles to do the tour, operators can pick you up in Herradura or Jacó. Budget (or time-conscious) travelers may want to simply stop near Río Tárcoles bridge where dozens of crocodiles gather on the banks. It’s easy to snap a few photos from the top of the bridge, but be sure to lock your car and
watch for oncoming traffic and Tourist Police, who make this a regular ticketing location for speedy drivers. The muddy river has gained a reputation as the country's dirtiest, thanks to San José's inadequate sewage system, but it amazingly remains an impressive refuge for wildlife. A huge diversity of birds results from a combination of transitional forest and the river, which houses crocodiles, herons, storks, spoonbills, and other waterbirds. This is also one of the few areas in the country where you can see scarlet macaws, which you may spot on a boat tour or while hiking in a private reserve nearby. If you have the time, take a dip in the pools of Catarata Manantial de Agua Viva, the highest waterfall in Costa Rica located 4 km (2½ miles) past Hotel Villa Lapas.
