Just outside Castleisland in Co. Kerry, Crag Cave is an easy, all-weather add-on to any Killarney/Tralee itinerary - a 30-minute self-guided tour through a beautifully lit limestone show cave, followed by coffee and cake upstairs or soft-play if you’ve kids in tow.

What is Crag Cave?

Crag Cave is a limestone show cave with about 3.8km of surveyed passage on two levels; roughly 30 minutes of it is open to visitors. Expect classic cave features, stalactites, stalagmites, flowstone, and a few Tolkien-tipped chamber names (you’ll hear about Helm’s Deep and The Hall of Moria on site). The show cave sits 72 steps below the visitor centre; the tour is self-guided with atmospheric lighting and audio.

It’s cool year-round down there (around 10°C/50°F), so a light layer and sensible shoes are best.

What’s On

Crazy Cave indoor play (up to age 12): mega slide, climbing frames, maze, ball guns, ideal for mixed-age family groups on a rainy day. Sessions are timed, so we recommend to pre-book in busy periods.
Garden Café & Gift Shop: coffee, bakes, casual bites, and a sizeable retail area attached to the visitor centre.
Seasonal events: look out for Halloween specials and a “Visit Santa” programme in winter.
Nearby: Crag Cave sits about 23km from the Wild Atlantic Way, so you can easily pair it with a spin round the coast.
