Exploring Aruba’s Ancient Rock Formations: Casibari & Ayo

Scattered across Aruba’s otherwise flat landscape are striking rock formations that seem almost out of place: clusters of boulders rising dramatically from the earth. Among the most impressive are the Casibari and Ayo Rock Formations, both offering not only natural beauty and panoramic views but also a fascinating window into the island’s ancient history.

A Glimpse into Aruba’s Past

Long before Aruba became a sought-after travel destination, it was inhabited by the Arawak people, indigenous inhabitants of the Caribbean who are believed to have settled on the island more than a thousand years ago. The Arawaks left behind more than stories at both Casibari and Ayo, visitors can still find prehistoric petroglyphs carved into the rocks. These ancient engravings, created by the Caquetío tribe (a subgroup of the Arawaks), are thought to have held spiritual or ceremonial meaning and serve as a powerful reminder of Aruba’s deep cultural roots.

Casibari Rock Formations

Located near Paradera, the Casibari Rock Formations are an easily accessible site, with well-maintained paths and stairs leading to the top. Climbing to the summit rewards you with 360-degree views of the island’s rugged north coast, central plains, and on clear days, even a glimpse of Venezuela on the horizon. The rock shapes, weathered by centuries of trade winds and rain, inspire the imagination and make for stunning photos.

Ayo Rock Formations

A short drive away, the Ayo Rock Formations feel more secluded and mystical. Surrounded by cacti and dry brush, the boulders here are larger and more tightly packed, creating small tunnels and shady spaces to explore. The site is considered spiritually significant and still carries a sense of quiet reverence. It’s easy to picture the Arawak people seeking shelter, carving their symbols, or performing rituals among these natural stone giants.

Tips for Visiting

• Bring water and wear sturdy shoes — while the climbs are manageable, Aruba’s sun can be intense.

• Visit in the early morning or late afternoon to avoid peak heat and get the best light for photos.

• Take your time: beyond the views and carvings, these sites are perfect for pausing and connecting with the natural and cultural history of the island.
