Stretching across northern Evia, Mount Telethrio (also Telethrion) forms an integral part of the region’s diverse geological landscape, alongside Lichada and Xiron mountains. This mountain is not only a vital ecological haven but also a site of deep historical and cultural significance. With elevations ranging from Mediterranean scrublands to oak and pine forests above 400 meters, it boasts a remarkable biodiversity that makes it a Natura 2000 protected area (GR2420005). The highest peak, Profitis Ilias (970m), can be accessed via several hiking trails or by off-road vehicles.
Human intervention has also shaped the mountain’s landscape, including a 330m² artificial lake constructed in 2013, which has influenced local microclimates. Despite the 2021 wildfires, which burned much of North Evia’s pine forests, the core oak-dominated zones of Telethrio remained intact.
The southern slopes of the mountain are home to two renowned monasteries, Saint George and Saint Irene Chrysovalantou, which attract pilgrims and history enthusiasts alike. Additionally, the ancient oracle of Apollo Selinuntius, an important religious site dating back to classical antiquity, provides further insight into the mountain’s rich historical significance.

Hiking and Outdoor Activities on Mount Telethrio
Hiking Trails
Mount Telethrio features an extensive network of hiking trails. The shortest routes to the highest summit of Profitis Ilias summit start from the village of Galatsades or Simia on the mountain’s north side. Both involve about 6km and 500m of elevation gain. The first one mostly follows dirt roads and is quicker. The second is harder and longer. On the summit, amid a charming oak forest, you find a picturesque little church and telecommunication installations.
Some more popular routes starting from Telethrio’s coastal side are:
Ilia – Monastery of Saint George (3.1 km): Beginning at the northwest edge of Ilia, this trail follows a concrete and then dirt road along a ravine before reaching the chapel of the Holy Apostles. From there, a well-marked forest path leads through dense woodlands, offering cool shade even in summer. The route ends at the historic Monastery of Saint George, where visitors can rest and refill their water bottles.
Dafnokouki Waterfalls: The short trail to the small waterfall (1.2 km) begins on a dirt road east of Ilia, leading to a narrow forest path marked with signs for “Small Waterfalls.” The trail ends at a series of cascading pools with crystal-clear water. The longer route to the large waterfall (4 km) follows a rugged dirt road to the start of a short, well-marked trail. The final stretch leads to a dramatic 27-meter waterfall plunging into a shaded natural pool, surrounded by towering trees and lush greenery. From there, you can also continue to Gymno Peak at 748m.
Polylofo (Gourgouvitsa) – Valanti Peak (4.3 km): This rugged trail begins near the village cemetery, following a dirt track before transitioning into a steep mountain path. Along the way, hikers pass through wild, untouched landscapes with expansive views. At the summit of Valanti Peak (890m), a large white cross marks a perfect spot to take in the scenery. From there, you have the option to continue toward Xeri and traverse to the north side of the mountain.
Other Outdoor Adventures
- Mountain Biking: Riding along abandoned logging roads is popular on Mount Telethrio and contributes €120,000 annually to local businesses. However, multipurpose land use remains a challenge, especially after a 2025 fatal accident involving forestry equipment.
- Off-Roading & Motocross: The mountain is a popular destination for off-road enthusiasts, featuring dedicated dirt roads and a motocross racetrack.
- Horse Riding: Several equestrian routes allow riders to explore Telethrio’s varied terrain at a leisurely pace. A horse-riding center operates near the village of Kamatriades.
Historical and Archaeological Significance of Mount Telethrio
Mount Telethrio has been referenced since antiquity, with Theophrastus (372–287 BCE) mentioning it in his History of Plants, calling it “Telethrion Syskion” due to its dense oak forest. This vast woodland stretched from the foothills near Kamaria, traversed by the Kallantas River (modern-day Xirias stream). Over time, this area became home to Istiaia, an ancient settlement once known as Xirochori, a name that persisted until recent history.
The mountain was also a significant religious site in classical times, housing the oracle of Apollo Selinuntius at Psili Rachi, as described by Strabo. Archaeological discoveries in 2001 uncovered pottery fragments and hydraulic structures, suggesting that purification rituals tied to the Kallantas River were performed here. The site saw continuous use from the 6th century BCE through late antiquity.
During the Byzantine period, many of Telethrio’s villages were established, and they have retained their historic character. In World War II, the mountain became a vital stronghold for resistance forces, with a guerrilla encampment near the village of Galatsades, where partisans waged their fight against the Axis occupation.
The Telaithrion Eco-community Experiment
Since 2010, a world-famous permaculture project has been operating on the northern slope of Mount Telethrio. Founded by the Athenian group Free & Real, the Telaithrion Project has focused on developing a self-sufficiency school and research center dedicated to sustainable living. On a 12-hectare site, the initiative experiments with natural farming, ecological construction, renewable energy, and self-sufficient living systems. It offers workshops and training programs that teach practical skills in permaculture, eco-building, and holistic sustainability.
With a vision of creating a functional model for self-sufficient communities, the project aims to provide an alternative way of living that is harmonious with nature and independent of conventional economic structures. Ultimately, it seeks to inspire and educate individuals to adopt sustainable practices that can be replicated worldwide. They are located here and this is their website.
