Trump Cave

The cave entrance sits tucked into the hillside near Larne, a modest opening that belies what lies beyond. Trump Cave is a proper spelunking challenge - not some tourist-friendly show cave with handrails and electric lights. You'll need a torch, sturdy shoes, and a willingness to crouch through narrow passages where the rock closes in around you. The passages twist inland, revealing natural chambers and formations that few people bother to visit, which is half the appeal. It's the kind of place where you genuinely feel like an explorer rather than just another visitor ticking off a checklist.

Walkers and geology enthusiasts will get far more from this than casual day-trippers. If you're looking for five-minute photo stops, keep walking. But if you've got even a passing interest in cave systems or just fancy something genuinely off the beaten track in County Antrim, it's worth the detour from Larne. You're looking at a couple of hours to explore properly, depending on how deep you want to go. Bring a mate - caves feel better with company, and you might need a hand squeezing through the tighter sections.

There's no visitor infrastructure here - no cafe, no gift shop, no opening hours to worry about. Free access, but come prepared. If you're based at Down to Earth Wild Camping just up the road, it makes a cracking half-day adventure between woodland walks and coastal exploring.
