On an isolated meander of the Río Bobonaza around 45km south of Puyo, Huella Verde puts even the bigger Yasuní lodges to shame by offering fascinating excursions in equally intact jungle for a fraction of the price: ethnobotanic jungle hikes, chocolate-making and canoe adventures with Kichwa guides (extra charges apply).
There is also a restaurant (mains $6 to $15). Two bungalows, each with private bathrooms and hammock-slung terraces, have capacity for just six – making reservations obligatory.
Head to the village of Canelos, off the Puyo–Macas road (a $25 taxi ride from Puyo), from where there's a complimentary canoe.
