Arsen Okrojanashvili Cave (Toba II)

Nestled in the Samegrelo region, deep within the rugged limestone massif of the Askhi plateau, the Arsen Okrojanashvili Cave—commonly referred to by speleologists as Toba II—stands as a premier example of Georgia’s karst formations. Unlike commercialized caves with concrete paths and artificial lighting, this site remains raw and authentic, offering a profound subterranean experience for those who truly appreciate the untamed wilderness.

Geological Profile and Features

As a vital component of the Toba cave system, this is an active hydrogeological site. The interior is defined by a dynamic subterranean river that has carved intricate galleries over millennia. Visitors are greeted by a surreal display of stalactites and stalagmites, along with active underground cascades that echo through the halls. The cave's location at a high altitude ensures a crisp, cool microclimate year-round, which feels especially refreshing after a hike during the Georgian summer. Because of the active water flow, surface conditions are consistently damp and slippery, requiring cautious movement through the chambers.

Practical Access and Safety

The journey starts in the village of Pirveli Balda in the Martvili municipality. Expect a 45–60 minute drive from Martvili town to the trailhead, followed by a scenic but moderately challenging trek through the local forest. Given the lack of clear trail signage and the technical nature of the terrain, hiring a local guide is highly recommended—not just for safety, but to understand the local karst geography. Proper footwear with deep-tread soles is a non-negotiable requirement. Furthermore, carry a reliable headlamp with extra batteries; natural light does not penetrate deep into the cavern.

Visiting Tips and Recommendations

The window for a successful visit opens in late spring and stays until early autumn. Outside of these months, seasonal snow and heavy rainfall often render the forest approach hazardous or impassable. When planning your trip, consider pairing this visit with the nearby Balda Canyon or the famous Okatse Canyon, both of which provide a deeper look at the limestone architecture of the region. Even on the hottest August day, remember to pack a windbreaker or a fleece layer; the humidity and low ambient temperature inside the cave can lead to quick heat loss.
