Between Boulders and Breeze: Climbing Aruba’s Ayo and Casibari Rock Formations
Scramble short faces, find Arawak petroglyphs, and watch Aruba unfold from rounded boulder summits
Oranjestad•By Robert Eric Crews•Land Adventures,Climbing Mountaineering,Wildlife Nature•March•winter
Continue ReadingYou arrive at Ayo and Casibari before the island fully wakes—late light pools between massive boulders, and the warm trade wind moves like a hand across the stone. The first steps are easy: a sandy pull-off, a low wall, then granite-colored blocks rising from scrub—rounded, stacked, improbably balanced. The formations read like a natural cathedral, but instead of soaring spires they're squat, weathered, and tactile. You can run your palm along the lichen-scattered faces and feel centuries of salt and sun.

Trail Wisdom
Trail Wisdom
Wear grippy shoes
Closed-toe trail shoes with good traction make scrambling safer and more comfortable on sandy, uneven surfaces.
Respect the petroglyphs
Observe ancient Arawak carvings without touching or trying to clean them to preserve fragile surfaces.
Bring water and shade
Even short visits can be dehydrating; carry at least 1 liter per person and a brimmed hat for sun protection.

Hidden Gems
- Small picnic alcoves beneath Casibari’s overhangs—great for cooling off after a scramble
- A narrow slot at Ayo that acts like a natural viewpoint for sunrise or sunset silhouettes

Conservation Note
Visitors are asked to stay on marked paths, avoid touching petroglyphs, and carry out all trash to protect fragile rock surfaces and native flora.
The rock formations are remnants of Aruba’s igneous geological past and the Ayo site contains Arawak petroglyphs, linking the stones to pre-Columbian island life.
