Riverside Sambú (sometimes appearing as Boca de Sábalo on maps) is an interesting stop, populated by Emberá, Wounaan, interioranos (or mestizos) and cimarrones (the ancestors of African slaves who escaped and settled in the jungle). Quite built up and populous by Darién standards, it makes a good springboard for visiting riverside indigenous communities further upstream and absorbing the slow jungle pace.
From Sambú, visitors can plan enjoyable trips across the Río Sábalo bridge to the twin village of Puerto Indio (with permission from the Emberá and Wounaan) and visit petroglyphs or mangrove forests. Another Emberá village worth visiting is Bayamón to the south. Bocaca Verano is a nearby lagoon with crocodiles and prolific birdlife.
