What to expect
You'll move through real mine workings, relying on your headtorch to navigate darkness. Some sections demand physical problem-solving—tight squeezes, climbing holds, abseil sequences. An underground boat crossing adds a distinctive element. The experience mimics wild caving conditions rather than purpose-built adventure parks; passages are unpolished and genuine. Expect to be cool, muddy and genuinely challenged. Your group controls the pace; optional elements can be skipped. Five hours allows thorough exploration without rushing.

Moderate fitness essential. Not suitable if pregnant or with spinal injuries. Request any personal equipment modifications 48 hours ahead.
