Essentials for Santorini in August
Wide-brimmed hat
Essential for protecting your face and neck from the intense August sun while exploring or lounging by the pool.

UV-protective sunglasses
Protect your eyes from the bright glare reflecting off the white buildings and the Aegean Sea.
Comfortable walking sandals
