Due to its strategic location, Gramvoussa was fortified by the Venetians, who built a well-fortified castle on the top of a steepy rock at an altitude of 137 m. Construction on the castle of Gramvoussa started in 1579 and ended in 1582.

Xylóskalo (Ksyloskalo GR: Ξυλόσκαλο) is the point where the Samarian gorge starts. It is located on the Lefka Ori (White Mountains) in the plateau of Omalos, 43 km from the city of Hania at 1250m above sea level. It is also the entrance to the gorge. There are two tourist lodges where visitors can rest and have food or coffee and take panoramic pictures of the gorge and the White Mountains. There is also the information center of the National Park and a parking area.
Xyloskalo means the "wooden stair" and refers to a wooden staircase built by the locals in order to facilitate the entrance to the gorge as at this point the cliffs are very steep. Today this part of the path is made of stones and it has a wooden handrail.
About 1km before Xyloskalo a dirt road leads, after 5 km, to the Kallergis mountain lodge at 1680m a.s.l.

Kallérgi Mountain Refuge is located on the western region of Crete, above the plateau of Omalos, in the White Mountains (Lefka Ori) mountain range at an altitude of 1680 metres.

It features a fully equipped kitchen, a lodge with fire place and wood burning stoves, toilets (indoors and outdoors) and a camping area. Electricity is supplied by a generator.

The Samaria Gorge is one of the longest ravines in Europe (with a total length of 16 km) and offers one of the most spectacular hiking routes in Europe. Its width ranges from 150 m (widest part) to 3 m (narrowest part). The walk from Xyloskalo in the plateau of Omalos to the shores of Libyan sea at Agia Roumeli, takes 6 to 8 hours. The Samaria Gorge has been designated as a national park in order to protect its flora and fauna. It is one of the last shelters of the mountain goat of Crete (Cretan Ibex, common name : kri-kri). The flora is extensive, ranging from high cypress trees to flowers and herbs. The walking path follows the river which flows to small lakes and waterfalls.
The Gorge is open to visitors from May to October.
