More ways to explore the area's outdoor wonders
You step off the whitewashed alleyways of Fira and the island’s edge takes over—rock that leans toward the sea, stairs carved into lava, and a trail that has been walked for centuries. The Aegean opens to your left in a slab of cobalt; to your right, cave houses press into the volcanic cliff like rooms hewn from memory. A guide nods, and the group moves along the caldera rim where every turn frames a different version of Santorini’s volcanic drama.

Bring plenty of water
Summer sun and exposed trail mean at least 1–2 liters per person; use the provided bottled water but carry a refillable bottle too.
Wear grippy shoes
The trail is volcanic rock with uneven steps—light hiking shoes with good tread are better than sandals.
Time your walk
Start early or late afternoon to avoid midday heat and the largest crowds in Oia; sunset draws big photo crowds.
Protect from sun and wind
Bring sunhat, sunscreen and a lightweight wind layer—gusts off the caldera can be sharp even on warm days.
Sturdy hiking shoes
Necessary for traction on uneven volcanic rock and steps.
Hydration bottle or pack
Keeps you hydrated on exposed sections—bring 1–2 liters depending on season.
