Mount Ainos, at 1,628 metres, is Kefalonia's highest point and the centrepiece of a national park covering the island's southern interior. The mountain is blanketed in Kefalonian fir — a species endemic to the region — giving it a dark, northern-European appearance that contrasts sharply with the sun-bleached coast below.
A road leads most of the way up, and a short marked trail reaches the summit from the car park. The walk takes about an hour each way and offers increasingly dramatic views over the island and the surrounding sea. The summit is cool even in summer — bring a layer. In winter, the mountain occasionally sees snow.
The national park is also notable for its wild horses — a small herd of semi-feral horses roams the upper meadows and can occasionally be seen near the road on the way up.
