Hiking may not be the first thing you think of when you think of Santorini.
But it's actually a very nice hiking island, despite the barren and treeless
landscape. My favourite hiking trails are these:
From Fira to Oia.
A wonderful hike that mainly follows the cliff edge.
From Pyrgos to Kamari.
Awesome hike from the mountain top down to the coast.
From Emborio to Kamari.
A hike where one pass by Ancient Thira.
From Perissa to Vlychada.
Seven kilometres along a refreshing sea.
If you are going to hike in Santorini, I recommend Anavasi's blue
map (1:26,000) which describes a variety of hiking routes in Santorini,
both easy and difficult. Terrain maps is another cartographic company
specialized in hiking maps. They have a map of Santorini with the scale
1:25,000 and it also describes many hiking routes. Both maps are available
for purchase at Santorini.
I recommend you to buy the hiking book Santorini, Sifnos, western
and Southern Cyklades by Dieter Graf. The book describes eight hiking
routes in Santorini in detail. The book is available for purchase in Santorini,
you can also buy it on internet if you want to plan your routes in advance.
