Your clothing choices directly impact your comfort and safety inside the cave. The environment 70 feet below ground is cooler and wetter than the surface. Follow these practical rules to ensure you are ready for the guided tour and the 125 stairs.
What is the temperature inside Doolin Cave?
The temperature inside the cave remains a constant 11°C (52°F) year-round.
You will not feel the summer heat or winter frost once you go underground. Bring a warm jumper or light jacket for the 50-minute tour. Leaving your jacket in the car is a common mistake on warm days.
What shoes should I wear to Doolin Cave?
You must wear sturdy, closed-toe walking boots or shoes with good grip.
Open-toed footwear is strictly prohibited. The cave floor features wet, uneven terrain. Sandals and flip-flops are not allowed past the entrance. Good grip is also essential for safely navigating the 125 steps.
Do I need to wear a helmet?
Yes, all visitors must wear a hard hat during the cave tour.
The staff provides these hard hats at the entrance. You must wear them at all times because the cave ceilings are very low in several sections. Avoid wearing bulky hats so the helmet fits securely.
What should I wear for the Doolin Cave Eco-Trail?
Pack a waterproof rain jacket and comfortable walking shoes for the 1km outdoor trail.
The Eco-Trail is a looped chip-stone pathway above ground. Weather in County Clare changes quickly. If you visit in summer, bring sunglasses and sunscreen. Your closed-toe cave shoes will work perfectly for this walking path.
Can I bring a bag into the cave?
You can bring a comfortable small daypack to hold your essentials.
Keep your bag compact. Large backpacks can scrape against the narrow cave walls. Use a small bag to carry your camera or smartphone. Flash photography is permitted inside the main chamber to capture the 7.3-meter Great Stalactite.
What items are not allowed inside?
Do not bring food, drinks, or animals into Doolin Cave.
These items are strictly banned underground to protect the delicate environment. You can purchase food and hot drinks at the onsite cafe after your tour.

Can I wear sandals?
No. Open-toed shoes are completely banned. You cannot join the tour if you wear sandals or flip-flops due to the wet, uneven floor.
