Piedra Blanca  is a small community found in a stunningly beautiful rainforest valley in Bolivar Province, Ecuador. Backpackers often rave about the place and most visitors discover the region by word of mouth. The local community is aware of the great tourism potential of the region but tries to keep a low profile (it's not in any guidebooks yet) as it it does not want a huge influx of visitors that might overwhelm the community and delicate ecosystems. A community run ecotourism project provides an alternative to logging as the locals accompany tourists to the rainforest, local cultural sites of interest, other local villages and on rafting expeditions of pre-Inca design.
A plentitude of rainforest animals, virgin rainforest, waterfalls, ancient stone inscriptions, ancient burial mounds, local markets, indigenous villages, stunning local landscapes, aguardiente farms, organic farms, riverside bathing pools, salt mines, traditional Ecuadorean villages, religious shrines, firework workshops and ancient trekking trade routes.
