Unique Features of Rudafshan Cave: From the Grand Entrance to the Anahita Hall

Rudafshan Cave stands out among Iranian caves for several distinctive features:

1. Massive Arched Entrance

Size: The entrance is about 40 meters wide and 12–20 meters high, making it one of the largest cave entrances in Iran.

Hidden Location: The entrance sits in a large hollow approximately 100 meters in diameter, invisible until you reach the edge—adding a sense of discovery and adventure.

2. Three Main Halls
The main cave passage stretches about 800 meters and includes three primary halls:

First Hall (Main Hall): Immediately after the entrance, measuring roughly 80 × 100 meters, with a ceiling height of up to 25 meters. Natural light from the entrance brightens this area.

Second Hall: Accessible after passing a historical stone wall, evidence of past human habitation. This hall has fewer stalactites.

Third Hall: Approximately 50 × 40 meters, the most beautiful section, with ceilings and walls adorned with stunning limestone formations.

3. Stalactites and Stalagmites (Limestone Formations)
The main attraction of Rudafshan Cave lies in its limestone decorations. Continuous water dripping forms:

Stalactites: Icicle-like formations hanging from the ceiling (spear-shaped, cauliflower-shaped, or pea-shaped).

Stalagmites: Columns rising from the cave floor.

Columns: Formed when stalactites and stalagmites meet.

4. Anahita Temple (Goddess of Water)
At the beginning of the cave, a corridor with a water pool and central column is known as the Anahita Temple, named after the ancient Persian goddess of water. This highlights the historical significance of water in the region and its connection to the cave.
