The six stepped pyramids are the visual anchor
The site's signature image is the set of six stepped lava-stone pyramids in Güímar. They are the reason most people stop, and in person they feel more deliberate than the quick roadside myth suggests. Even if you arrive skeptical, the layout pulls you into the bigger question of why this corner of Tenerife became such a lasting curiosity.
1991 made the solstice story harder to ignore
Research in 1991 confirmed the complex's alignment with the summer and winter solstices. That does not settle every debate around the structures, but it explains why astronomy remains central here and why the June 21 double-sunset event became the site's signature special date.
Thor Heyerdahl turned a threatened site into a park
In 1990, Thor Heyerdahl focused his attention on the abandoned pyramids of Güímar. He moved to Tenerife in 1994, and founded the park in 1998 to protect a complex that was at risk under urban planning. That timeline matters, because the place you walk today is as much a preservation project as a curiosity stop.
The visit widens beyond the pyramids
What makes the park less one-note is how quickly it broadens after the first viewpoint: the Cueva Chacona story beneath Pyramid 1, the 19th-century Casa Chacona, the Poison Garden, An Ocean... of Plastic, and the Polynesia section. If you came only for a photo, this is the moment the visit either wins you over or sends you cheerfully into full unexpected-museum-rabbit-hole mode.
2017 changed the park's identity again
Since 2017, the site has also defined itself as a botanical garden, not just an ethnographic stop. That shift explains the live plant collections, the ravine-style Sustainable Garden, and the stronger environmental thread running through the park today. It sounds like a small label change before you arrive, but on site it changes the whole rhythm of the visit.
