The main tunnel is only 1.5 - 1.8m high and 1 - 1.2m wide, with many winding sections and clay floors that get slippery when damp. You should prioritize comfort and bodily protection.
Recommended attire:
- Clothing: Choose T-shirts, thin breathable shirts, and comfortable long pants or jeans. Avoid thick jackets or tight-fitting clothes as they cause heat and restrict movement.
- Footwear: Sneakers or soft-soled shoes with good grip are the top choice. Absolutely do not wear high heels, flip-flops, or sandals as they slip easily.
- Accessories: A cap or wide-brimmed hat to prevent hitting your head on the tunnel ceiling. Bring a light jacket or shawl as it is cooler inside the tunnels than outside (especially in the early morning or late afternoon).
- Rainy season (September - December): Bring a light raincoat and waterproof bags for your phone and documents.
Important note: Do not wear offensive or overly revealing clothing, as this is a historic site that requires respect.
