The Interamericana runs from Panamá Province along the spine of Darién Province, with Yaviza literally at the end of the road. Police checkpoints are frequent along this road, so have your passport (and five photocopies of it) ready and be prepared to discuss your travel plans.
Some 45km southeast of Lago Bayano is the town (or towns) of Ipetí: Ipetí Choco, Ipetí Guna and Ipetí Colono. Each is occupied by a different cultural group (Emberá, Guna and interiorano, or 'Latino').
Twelve kilometers past Ipetí is the village of Tortí, a useful stop with two hotels, restaurants, a police station and a health clinic.
