What shoes do I need for Prometheus Cave?
You need closed-toe shoes with a solid grip.
The walking trail inside the cave is paved, but it is often wet. Moisture drips from the stalactites, making the surface slippery in some sections. Leave your sandals and flip-flops at your hotel.

Do I need a jacket in summer?
Yes, you should bring a light waterproof jacket.
Summer months like July and August get very hot outside the cave. When you descend 40 to 80 meters below sea level, the sudden drop to 14°C feels quite cold. Pack a light layer you can easily take off later.

What else should I pack for the cave tour?
Bring a small daypack, a low-light camera, and cash.
- Daypack: Useful for storing your jacket when you exit the cave.
- Camera: You need a device capable of low-light photography.
- Cash: Bring local GEL for entrance tickets in case card machines fail.

What to wear for the underground boat ride?
You do not need special clothing for the boat, but life jackets are mandatory.
The optional boat ride covers 380 meters on the Kumi River at the end of the tour. The staff provides mandatory life jackets on-site before you board.
Should I wear different clothes for Martvili Canyon?
Yes, Martvili Canyon is open-air and requires sun protection in summer.
If you visit both sites in one day, dress in layers. You will need sunglasses and sunscreen for the open-air trails and rowboat ride at Martvili Canyon. A small daypack helps you manage these layers easily.
