There is a fence around it and an entrance on the east side where you can follow a steep footpath to the bottom. Some 2 km north of Agios Konstantinos near the peak of a rocky hill you will find the cave of Kitsos. It was inhabited during the Palaeolithic and Neolithic era, about 40,000 years ago. Archaeological finds include obsidian from Milos, ceramic moulds for silver and a copper pin dating over 7,000 years. Mor recently, the cave was the lair of Kitsos, famed bandit and bodyguard of Serpieri who raided the region around 1860.
An hour away by foot from Agios Konstantinos, walking uphill on a sand road, you reach the cave on the eastern slope of a rocky peak called Mikro Rimbari. The route takes you through dense Aleppo pine forests, parts of which burned down during different forest fires sadly. After the sand road take the footphat to the left, walkinb between holly oak, thorny fabaccae, and phrygana until you reach impressive rock formations, enormous concave arches and massive monoliths that have fallen from the peak. White or yellow lichen color the grey rock, and lush green moss grows in shady spots. Chasmophytes such as inula candida grow in rock crevices. The peak of Mikro Rimbari above the cave has a great view of the seas all around. Note the autumn crocus and Cartwright’s crocus growing all over the slopes in autumn.
North of the temple of Poseidon are rocky outcrops named Mavro Lithari and Vasilopoula. From the main Athens-Sounio road, a small sand road heads west of Vasilopoula peak. The crested lark’s whistle accompanies you north towards the grey-blue rock at a peak that’s 260 meters in altitude. Mediterranean shrubs and phrygana as well as sharp rocks characterize this arid landscape. During bird migration period, i.e. spring and fall, you can come across many birds of prey. Return to the beachfront road walking along a dry river bed towards Legrena.
