Hydra has no cars, so its old paths still lead somewhere: to remote monasteries, quiet coves and ridges looking out over the Saronic and Argolic gulfs. Hydra Trails is the island’s official network of waymarked hiking routes, mapped and signed so you can explore on foot with confidence.
Free to use, with offline maps, GPS navigation and 3D maps. Download the trails before you leave the port and walk with confidence, even where there is no signal.
There are daily itineraries that do not exceed one and a half hour, with ferry, flying dolphin and flying cat vessels to and from the port of Piraeus. The same itineraries link Hydra to the other islands of Argo-Saronic and Spetses.
Hydra is connected to Ermioni and Metochi by boat, with itineraries of no more than half an hour.
Hydra has no wheeled vehicles, they are forbidden! To cut a long story short, in order to move you will have to walk!
You can also move around the island mainly using animals, but also with water taxis that can take you to various places by sea when the weather allows it.

In Hydra, you can hike all year round. Spring and Autumn are considered to be the best seasons to hike due to the mild temperatures and the vivid colours of the land and vegetation. In winter it is also possible to hike, but you should expect a few showers, strong and cold winds and muddy trails. In summer (July, August) it is too hot to walk. However, if you try it, avoid walking between 12pm to 4pm.
Hiking boots, hat, sunscreen, long trousers, walking poles are considered essential. During winter time, a windproof jacket, a raincoat and thermal apparel are required. It is also advised not to walk alone and to always keep with you a first aid kit. A torch, and a well charged mobile phone are also advisable, however keep in mind that there are areas with no cell-phone reception on the island.
