Geotours has been working out of the same corner of Ambato and Halflants since 1991, which in a town with ninety-six registered agencies counts for something. The office runs three languages — the site is published in English, Spanish and Dutch — and sells the whole Baños repertoire plus Cuyabeno trips out of the jungle.
The one price they publish is a full day of birdwatching at $180 a head, which tells you where the serious end of their business is. Everything else is quoted on the day, as it is everywhere in Baños.
Open 07:30 to 20:30, seven days. The WhatsApp button on the site is the same mobile they print as their phone number, so there is no ambiguity about where a booking message lands.
