Santa Cruz to Cochabamba

There are two routes west from Santa Cruz to Cochabamba. An older partly paved road goes via the mountains and Samaipata. A newer, almost fully paved, lowland route further north goes via Buena Vista and Villa Tunari in the Chapare region; it is preferred by most transport. Parques Nacionales Amboró and Carrasco are situated between these two routes, with various accesses to both parks along both roads.
