The Aggitis River Cave, also known as the Maaras Cave, is the only river cave in Greece accessible to the public. It forms part of a subterranean river system that serves as the main drainage outlet for the Drama plain. The cave extends for approximately 21 kilometers, though the public pathway covers only the first 500 meters of its length. The cave features a consistent internal temperature throughout the year, independent of external weather conditions. Water flows through the entire accessible section, with the river emerging from a natural siphon. The interior displays a variety of formations, including stalactites and stalagmites, alongside a Neolithic-era rock painting discovered near the cave entrance. The site is located in the prefecture of Drama, nestled at the foot of the Falakro mountain range.

If visiting during peak summer weekends, arrive early to avoid potential queues.
Do not attempt to walk off the marked path or touch the water, as the cave floor is slippery and the river depth is inconsistent.
The cave is typically open daily, though hours may be restricted during extreme weather conditions if the river level rises.
Do not touch the rock formations, as oils from human skin can stop their growth; flash photography is often restricted to protect the cave's sensitive environment.
