Santorini hiking is led by the spectacular Fira-to-Oia caldera trail, with shorter walks to Skaros Rock, the Profitis Ilias monastery and the craters of the Nea Kameni volcano. The clifftop paths offer some of the finest views in Greece. This guide covers the best trails, the difficulty, the timing and tips for hiking.
Walking is one of the best ways to see the wider Santorini travel guide. The caldera rim is made for it. The sections below cover hiking.
What is the best hike in Santorini?
The best hike in Santorini is the Fira-to-Oia caldera trail, a roughly 10-kilometre walk along the cliff edge through Firostefani, Imerovigli and on to Oia. Taking 2.5 to 5 hours, it is rated the top thing to do on the island for its continuous, breathtaking views over the caldera and volcano.
One walk stands above all others. The Fira-to-Oia hike follows the caldera rim for about 10 kilometres from the capital, passing through Firostefani and Imerovigli before the path turns wild and remote on the stretch to Oia, with the bay, the volcano and the sea spread out the whole way. It takes anywhere from two and a half to five hours depending on pace and photo stops, on a mix of paved promenade, cobbled lanes and rough natural trail, and is consistently rated the single best thing to do on Santorini. Most walkers start in Fira in the cooler morning or late afternoon and finish in Oia for the sunset, set within the wider Fira to Oia hike. Other trails reward too.
What other trails are there?
Other trails include the short, dramatic walk out to Skaros Rock below Imerovigli, the climb to the Profitis Ilias monastery on the island’s highest peak from Pyrgos, and the volcanic hike to the craters of Nea Kameni. Each is shorter than the Fira-to-Oia route but offers superb views and history.
Beyond the famous rim walk, several rewarding trails fan out across the island. The short, exposed path from Imerovigli leads out to Skaros Rock, the crag that once held the island’s medieval capital, and down to the hidden Theoskepasti chapel beneath it. From the hilltop village of Pyrgos, a marked 2.5-kilometre trail climbs to the fortress-like Profitis Ilias monastery on Santorini’s highest peak at 565 metres, with panoramas over the whole island. On the volcanic islet of Nea Kameni, reached by boat, a gravel path winds up among steaming sulphur vents to the craters. Each is a half-day at most but full of drama and history, set out alongside the guides to Skaros Rock and the Profitis Ilias monastery. The walking is moderate.
How difficult is hiking in Santorini?
Hiking in Santorini is moderate, needing a reasonable level of fitness rather than experience. The Fira-to-Oia trail is not technical but has several steep climbs, uneven ground and little shade, while shorter walks like Skaros Rock include steep steps and loose gravel. Good shoes and water are essential.
The trails are achievable for most but not effortless. The Fira-to-Oia path is not technically difficult, with no climbing or exposure on the main route, but it does involve several steep ascents and descents, particularly the sharp climb from Fira up to Imerovigli, on terrain that ranges from smooth paving to rough, stony dirt. The shorter trails to Skaros Rock and the monastery add steep steps and loose gravel with exposed drops. None requires special skill, but a reasonable level of fitness, sturdy shoes with grip and plenty of water are essential, as much of the route is hot and shadeless under the summer sun, set out alongside the guide to the Santorini caldera. Timing makes a big difference.
When should you hike and what to bring?
You should hike early in the morning or in the late afternoon to avoid the midday heat, ideally in spring or autumn rather than peak summer. Bring sturdy shoes, plenty of water, sun protection, a hat and a charged phone, and start the Fira-to-Oia walk early enough to reach Oia by sunset.
Smart timing turns a hot slog into a pleasure. The midday sun is fierce and the trails are largely unshaded, so set out early in the morning or from the late afternoon, and favour the milder, quieter shoulder seasons of spring and autumn over the searing peak of July and August. Wear proper walking shoes or trainers with grip for the uneven ground, and carry far more water than you think you need, along with sun cream, a hat and sunglasses. A charged phone with an offline map helps on the wilder stretches, and there is little to buy between Imerovigli and Oia, so pack a snack. Plan the Fira-to-Oia walk to finish in Oia in time for the sunset, set out alongside the guides to the sunset and the best time to visit Santorini. The questions below cover the points travellers ask most.
