In an altitude of 80 meters, about 500 meters northwest from the area of Rousolakkos-Palekastro and close to Chiona beach, there is the visible opening of the cave of Petsofa, which was named after the hill. It is a very small cave (about 3x5m) with a large archeological importance, as here many broken amphoras as well as a number of inscriptions have been found.  

Another important cave of the province is the cave of Peristeras. It is located 2km east from the village Karydi, in the area of Platyvolas, in an altitude of 540 meters. It has a rich rock decoration and 170 meters of explored routes. Here too, signs of human presence were discovered, dating back to the Neolithic period.

The cave Okso Latsidi is located in the area of the village Sitanos and it is part of an extended cave complex that expands for more than 6,000 meters in the subsoil of mountainous Sitia. It is one of the richest carst formations in Crete.

The castle fortress known today as "Kazarma" (Casa di arma), is the most imposing historical monument in Sitia.

The Kazarma used to be a military and administrative centre which consisted of a Medieval dwelling surrounded by walls. The fortification of the town and of the Kazarma can be dated to the late Byzantine period.

Etia probably took its name from the tree Itea (willow) The village seems to have been populated since the Byzantine period as one can see from the remaining churches of Aghios-Ioannis and Aghia-Ekaterini. During the Venetian reign it was on of the largest villages of the area with 563 citizens.

The deserted settlement of Voila occupies the north and west sides of the steep hill located on the eastern side of the Armenochantrades plateau. On the southeast side the settlement is protected by the steep cliff. In the north and western sides of the hill, the houses are built like fortifications, while a short wall is protecting the remaining perimeter towards the valley.

According to the evidence of recent excavations it would appear that the site of Hellenistic Sitia is situated at Tripitos, a small headland 3 kms east of Sitia and 15km west of Palekastro village.

Petra is a traditional settlement, 1 km east of Sitia. A small tower from the Venetian period can be found there. It bears the name "house of Kornaros" and belonged to the homonym family. On the hill over the tower, a small palace and a settlement have been brought to light by recent excavations. The rooms of the palace were luxuriously adorned and its walls painted with bright colours.

The enchanting gorge and waterfall of Richtis (or Rihtis gorge) can be “discovered” in Eastern Crete by a distance of 32km from Palekastro and 50 from Zakros. It starts from the traditional village “Exo Mouliana”, which is located on the national road between Agios Nikolaos and Sitia and ends at the secluded Richtis beach, just east of the village Kalavros.

Access to Karoumes beach can be done only by walking in the gorge of Hochlakies, which starts east of the village of Hochlakies, since the rugged terrain of the area has kept off the roads. Thus, in order to come here you should leave your car in the picturesque village of Chochlakia and follow the trail that starts 1km east of the village.
