About Us

Guillermo Rivera is owner, operator and tour guide of Plant Expeditions (formerly Cactus Expeditions and South American Nature Tours).

Before starting his career as a habitat guide, Guillermo obtained his PhD in Botany and was a researcher at the University of Cordoba, and was employed at the Cordoba Botanical Gardens.

Since the first tour in Argentina and Chile in 2001, our tours have expanded to over 10 countries, including Bolivia, Brazil, Ecuador, Madagascar, Mexico, Namibia, Peru, Socotra, South Africa, Singapore and Thailand.

Tours are typically 14-16 days, with some offering 1 week extensions (e.g. Kruger National Park, Galapagos, Manu National Park in Peruvian Amazon, a trip to Antarctica if logistics allow after Southern Patagonia tour).
