To imbibe the Tena vibe, take a turn along the malecón (waterfront) which runs east and west along the banks of the Río Tena for a few blocks. Tena's newer (southernmost) footbridge, connecting across to Parque Amazónico La Isla, has a futuristic-looking mirador (viewing tower). Cross the river on this one; come back on the old footbridge, just north. Market days are Friday and Saturday.
