Fodor's Expert Review Vale do Pati

One of the country's most scenic treks, this onetime pilgrim trail of the Tupi Indians takes you between towering sierras, through caves, and past waterfalls. The 70-km (43-mile) trail starts in Bomba, climbs to Candombá Hills, follows a plateau at Gerais de Vieira, then goes alongside the steep Rio Paty toward Andaraí. Along the way, you can either camp or sleep in simple, clean wood huts provided by locals. Although the trek itself is not challenging, it does cover a considerable distance spread over four days and requires a general level of fitness and good walking shoes. A six-day trek is also available.
