History
Raufarhólshellir formed when surface lava crusted over while molten lava drained away; its size reflects a high-volume, effusive eruption in Iceland’s volcanic past.
Conservation
The tube is sensitive—avoid touching or removing formations, stick to paths, and pack out all waste; the operator emphasizes low-impact transfers and carbon-neutral options.

Wear grippy footwear
The cave floor is uneven and can be slick; closed-toe hiking boots with a firm sole improve traction and ankle support.
Layer up
Tunnel temperatures stay near freezing—bring a warm midlayer and a windproof shell for comfort during stops and transfers.
Bring a headlamp
A personal headlamp keeps your hands free for scrambling and framing photos; tours provide flashlights but extra light is useful.
Mind children and low ceilings
Minimum age is 3; watch younger children carefully for low sections and uneven footing—consider the family’s mobility before booking.
Sturdy hiking boots
Provide traction and ankle support on uneven, potentially slick cave floors.
Warm midlayer and windproof shell
Keeps you comfortable inside the cool tunnel and during transfers by coach.
Headlamp or personal flashlight
Hands-free illumination helps during low-light sections and enhances photography.
Gloves and warm hat
Small accessories that add comfort—cave air is often near freezing even in summer.
