8 Best Adventure Days Out In Gwynedd
Slate is the reason this category exists in Gwynedd. Six of the eight records are quarry or mine workings put to a second use — Zip World Llechwedd and Zip World Penrhyn Quarry on ground the industry left behind, Llanfair Slate Caverns and Sygun Copper Mine underneath it, and National Slate Museum at the foot of a worked face. Adventure here means going into a mountain, or going across the hole one was cut out of, and those are very different afternoons.
Treat the total with a little care. One entry is listed simply as The Slate Caverns, which reads like a second line for a site already named above, so plan around seven distinct places rather than eight. Another is a printed town trail you follow on foot, not a venue with a car park and a desk.

The pattern worth holding on to is this: rock over your head does not care about the forecast, and a wire strung across a quarry does. If the sky looks unsettled, take the one you walk into and keep the zip line for a clear morning.
Adventure Days Out in Gwynedd: FAQs
What is going underground actually like for a child who has never done it?
Dark, cool and echoing, and for most children that is the appeal rather than the problem. Llanfair Slate Caverns and Sygun Copper Mine take you into worked ground rather than a show cave, so expect steps, some low headroom and a guide setting the pace for everybody. A child who likes a story told in the right place tends to take to it straight away. A child who dislikes enclosed spaces will know inside the first few minutes, which is worth weighing before you commit the whole party to a tour you cannot easily leave.
Zip line, or something gentler for the youngest?
Zip World Penrhyn Quarry is the headline name and the one with the height, the harness and the size rules you need to check before travelling. If that rules out the smallest in your group, National Slate Museum covers exactly the same industrial ground at walking pace, with both indoor and outdoor space listed and nobody strapped to anything. Electric Mountain is the other roofed option here, and it asks nothing of a child but attention.
Does wet weather write off adventure days in this part of Wales?
Less than you would fear. Five of the eight carry an indoor flag, and in Gwynedd that often means inside the hill rather than inside a building — the mountain keeps rain off as well as any roof. Zip World Llechwedd shows both indoor and outdoor space, so part of what is there sits under cover. The genuinely exposed choices are the wire across the quarry and the walking trail round town, and both of those want a dry morning to be worth the trouble.
