Guanare sits on the edge of the Portuguesa state llanos — the vast, flat Venezuelan plains that stretch from the Andes foothills to the Orinoco River. This is one of South America's great wildlife habitats: seasonally flooded savannahs that support large populations of capybara, caimans, anacondas, marsh deer, and an astonishing diversity of waterbirds including jabiru storks, scarlet ibis, roseate spoonbills, and numerous species of herons and egrets.
Wildlife-watching excursions from Guanare are possible with local guides, though the more established llanos tourism infrastructure is centred on hatos (ranches) further south in Barinas and Apure states. The area around Guanare offers a taste of the llanos without the organised tourist facilities — more improvised, cheaper, and potentially more authentic.
