Walking & Hiking
Hydra’s mountainous, arid interior makes a robust but peaceful contrast to the clamour of the quayside. A useful map for walkers is Anavasi's Hydra map. A map is posted on the quay, and several marked trails extend across the island. Once you leave the villages of Hydra/Kamini/Vlyhos there are no services. Take plenty of water. Springtime is perfect for flower-strewn hillside walks.
An unbeatable experience is the long haul up to Moni Profiti Ilia. The wonderful monastery complex contains beautiful icons and boasts endless, dramatic views. It’s a solid hour or more through zigzags and pine trees to panoramic bliss on top.
A smaller monastery, Moni Agias Efpraxias, sits just below Profiti Ilia and is run by nuns.
Other paths lead to Mt Eros (588m), the island’s highest point, and east and west along the island spine, but you need advanced route-finding skills or reliable directions from knowledgable locals.
