The Experience

I still laugh thinking about that first clunky step onto the old mining train — it rattled so much I half-expected my water bottle to jump out of my bag. We’d left Bled before sunrise, all a bit groggy, but our guide (Petra) was already joking about “the black hole” ahead. The drive felt long but the mountain roads were quiet, just mist and the odd farmhouse blinking by. When we finally stopped at the mine entrance, it looked like something from another century — rusty rails disappearing into a dark tunnel, cold air breathing out at us.

The descent took fifteen minutes on that train, down and down until daylight vanished. My ears popped somewhere in the middle. Petra handed out dry suits and helmets while telling us stories about miners who used to work here — apparently they’d whistle to hear if anyone else was nearby, since sound travels weirdly underground. There’s this smell I can’t describe exactly — not dirt, not quite metal either — just cold and old. We climbed steep stairs (my legs noticed), then suddenly there was water lapping against stone walls and our kayaks lined up like ducks in a row.

Paddling through those flooded tunnels with only our headlamps was… honestly strange at first. You can’t see more than a few meters ahead; everything echoes differently down there. At one point Petra switched off her light for a minute — total blackness except for someone’s nervous laugh (okay, maybe mine). The water was colder than I expected but my hands got used to it fast. It’s hard to explain how quiet it gets between paddle strokes — you start hearing your own heartbeat or maybe that’s just nerves? After an hour or so we clambered back up towards daylight again, blinking like moles.

I didn’t expect to feel so small down there. Back on the surface, with everyone shivering and grinning over snacks, I realized I hadn’t checked my phone once all day — not even sure if there was signal anyway. The whole thing felt both surreal and oddly grounding; sometimes you need to get lost underground to remember what fresh air tastes like.

What’s included

Your day includes hotel pickup and drop-off in Bled (or meeting point if you’re staying elsewhere), all kayaking equipment like dry suits and helmets, bottled water and snacks along the way—plus a ride on that original mining train before heading back above ground at the end of your adventure.
