The Güímar Pyramids are one of Tenerife's most controversial archaeological mysteries — six step structures built from dry stone whose origins and purpose remain debated among researchers and enthusiasts.
To know: The site is managed by the Parque Etnográfico, which includes a museum dedicated to explorer Thor Heyerdahl. Plan 2 hours for a complete visit.
Discovered beneath scrubland in the 1990s, the pyramids were restored and studied thanks to the interest of Thor Heyerdahl — the Norwegian explorer famous for the Kon-Tiki expedition. He championed the theory of a link between these structures and the pyramids of Central America.
Conventional archaeologists lean more towards Guanche or colonial agricultural terraces. The debate remains unresolved.
What is certain: the pyramids are precisely aligned with the sun at the solstices.
The site includes a museum about Thor Heyerdahl and his expeditions (Kon-Tiki, Ra, Tigris), a reconstruction of a Guanche house, and botanical gardens featuring endemic Canary Islands plants.
A good option on cloudy days in the eastern part of the island.
