Most of the trails start from the villages, which are located at the foot of Oitis and ascend to the peaks. From the Northern side the visitor can climb up Oitis from Ypatis, Loutra Ypatis, Kombotades, and Mexiates. From the western slope it is accessible from Neohori and Kastania. And from the Southern slope through Pavliani, Kastriotissa and Pyras. From the eastern side, one can climb up from Gorgopotamos.
In the morphology of the mountain, all the sides except the southern one are steep, while the villages built at the foot of the mountain are at low altitude and as a result only experienced hikers can climb from this starting point. On the contrary, the southern side has flatter slopes but its villages are at an altitude of 1,000 m., decreasing in altitude towards the peak. For experienced hikers, climbing from the Northern slope is a unique experience. The paths are quite distinct and some of them are sufficiently marked.
In particular, 9 routes cross the Oiti mountain range and constitute a network of paths that are connected to each other, either at Trapeza refuge or at Greveno summit, or at Pyrgos peak, the tallest of Oiti. These routes are barely explorable in one day and a better choice for the visitor is to spend at least two days staying overnight in the refuge or in a tent. The routes are as follows:
- Ypati - Trapeza refuge - Greveno peak - Pyrgos peak
- Pavliani - Katavothres Plateau - Pyrgos peak (in combination, routes 1 and 2 cross over at Oiti)
- Loutra Ypati - Trapeza Refuge
- Mexiates - Karitsa Plateau (this route meets route 3)
- Argyrohori - Karitsa plateau
- Ypati - Arsali Monastery
- Louka plateau (above the Kombotades) - Greveno peak
- Kastania - Pyrgos peak
- Neochori - Pyrgos peak
You can wander down two other routes, starting from Papadias Bridge towards Trachis train Station (following the train line) or crossing Asopos River, you end up in Sperheios valley.
