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
You 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
Start early or late
The rock heats up quickly—visit at sunrise or late afternoon to avoid the midday sun and catch the best light.
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.
Local Knowledge
Hidden Gems

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.
Seasonal Guide
spring
Best for: fewer crowds, comfortable temperatures, wildflower spotting
Challenges: occasional showers, hot afternoons late season
Spring (Mar–May) offers warm days and thinning winter crowds—great for exploratory walks, though expect rising temperatures by mid-May.
summer
Best for: long daylight hours, photography in golden light, combo beach days
Challenges: strong sun, higher humidity, heat by midday
Summer brings intense sun and heat—plan morning visits, use sun protection, and pair with a beach swim to cool off.
fall
Best for: mild weather, fewer tourists, clear horizons for views
Challenges: brief rainy spells, sticky humidity on some days
Fall is pleasantly warm with lower tourist density; brief rains can make rock surfaces gritty, so give them time to dry.
winter
Best for: cool breezes, peak visibility, ideal hiking conditions
Challenges: highest tourist season, limited parking on busy days
Winter (Dec–Feb) is Aruba’s high season—cool trade winds make scrambling comfortable but plan for more visitors and limited parking.
