Right by the train station are traditional tavernas, such as the famous "Romance Tavern," which has often served as a backdrop for Greek films. The station is a popular starting point for hikes through the gorge along the railway tracks, especially to Diakopto (approx. 12 km, 3.5-4 hours). Another trail leads up to the Mega Spileo Monastery, founded in the 4th century and built directly into a cliff face. The area is characterized by dense forests of plane trees, chestnut trees, and pines, as well as numerous waterfalls in the gorge.

The Chelmos Observatory (Greek: Αστεροσκοπείο Χελμού) is a major astronomical research facility located on the summit of Neraidorachi in the Chelmos mountain range. It is situated at an altitude of 2,340 meters above sea level. This location was chosen because it is among the darkest places in continental Europe and is hardly affected by artificial light pollution. The observatory is involved in important international projects: It was selected by the ESA as the first optical ground station under the ScyLight program to test laser communication with satellites. The telescope supports experiments in quantum communication and communication with distant probes, such as NASA's Psyche mission.
