Wieliczka gets the fame, but Bochnia is Poland's oldest salt mine and a genuine alternative rather than a lesser copy – older tunnels, far fewer visitors, and a couple of things Wieliczka simply doesn't have.
What makes Bochnia different
The standout is an underground boat ride along a flooded brine channel, plus a slide connecting two levels of the mine – both unusual additions that make Bochnia feel more like an adventure than a museum walk. It doesn't have anything to match Wieliczka's carved Chapel of St Kinga, but it also doesn't have Wieliczka's crowds.
Bochnia or Wieliczka
If you're choosing one: Wieliczka is the easier, more famous, more visited option, and the right call if the chapel is what you came for. Bochnia suits visitors who've already done a salt mine before, want something quieter, or are travelling with kids who'll enjoy the boat and the slide. Doing both on the same trip isn't repetitive – they're different enough – but most people pick one.
Getting there
Bochnia is about 45 minutes from Kraków, a bit further than Wieliczka and less convenient by public transport, so a tour that includes transport is the practical choice unless you're driving yourself.

Frequently asked questions
Wieliczka has the grander sights – the carved Chapel of St Kinga is the reason it's world-famous – and is far easier to reach without your own transport. Bochnia is older, much less crowded, and adds an underground boat ride and a slide that Wieliczka doesn't have. If you want the famous chapel, go to Wieliczka; if you want a quieter, more playful visit, Bochnia is the better pick.
