Quick Answer: Is Zip World Llechwedd Giant Nets Worth It?
If you’re planning a North Wales day out and wondering whether the giant nets adventure at Zip World Llechwedd is worth the trip, the short answer is yes — for the right family. It’s underground, it’s active, and it runs whatever the weather. But before you book, there’s one thing to know: tickets here are for specific adventures, not one all-access pass. Picking the right one for your group makes all the difference.
TL;DR: Quick verdict
- Giant Nets (officially called Bounce Below) is a brilliant choice for energetic families who want something genuinely different from a standard day out
- It’s fully underground, so rain, wind, and grey skies don’t affect it at all
- Tickets are activity-specific — you’re booking Bounce Below, not the whole site
- Book online in advance and arrive 30 minutes before your start time
- Allow 3 to 4 hours on site overall to make the most of the visit
What Is Giant Nets at Zip World Llechwedd?
The giant nets experience at Zip World Llechwedd is officially named Bounce Below, and it’s one of those activities that’s genuinely hard to compare to anything else. You go underground into the caves of a disused slate mine in Blaenau Ffestiniog, and inside you’ll find six enormous trampoline-style nets suspended across three subterranean levels.
Think less trampoline park, more underground playground. The nets are built into the cavern walls, so the space around you is raw rock and dramatic cave architecture. That setting is a huge part of what makes it special — it’s not just bouncing, it’s bouncing in a place that looks and feels unlike anywhere you’ve ever been.

Who Will Enjoy It Most?
Bounce Below suits families who want energy, excitement, and something they won’t find at a standard soft play or leisure centre. That said, it’s worth being honest with yourself about your group before you book.
Great fit for…
- Energetic kids and adults who love climbing, jumping, and exploring unusual spaces
- Mixed-age families where everyone is at least 1m tall and happy underground
- Holiday visitors near Blaenau Ffestiniog looking for a half-day activity that doesn’t depend on the weather
- Families who’ve done the usual theme parks and want something that feels genuinely different
- Anyone who finds standard trampoline parks a bit samey — the cave setting transforms the whole experience
Worth thinking about first…
- Younger or smaller children who don’t meet the 1m minimum height requirement won’t be able to take part in Bounce Below — check the specific rules on the booking page before you travel
- Children who are nervous in enclosed spaces may find the underground environment more daunting than exciting, so it’s worth having a chat before booking
- The site has multiple adventures, and not all of them are suitable for every age group — Bounce Below is one of the more accessible options, but it’s still worth checking requirements for your specific group
The real appeal? It’s one of the few activities in North Wales that genuinely works in any weather, at any time of year!
What to Know Before You Book
The most common planning mistake at Zip World Llechwedd is assuming one ticket covers everything. It doesn’t. Each booking is for a single named adventure, so you’re choosing Bounce Below specifically, not a general site pass. Get that right and the rest is straightforward.
Here’s everything worth knowing before you confirm your booking:
| What to check | The detail |
|---|---|
| Ticket type | You’re booking Bounce Below only — not all-access to the site |
| Price | From £25 via Zip World directly; from £33 via Day Out With The Kids depending on date and availability |
| Minimum height | 1m for Bounce Below — check the live booking page to confirm current requirements |
| Arrival time | Arrive at least 30 minutes before your booked start time for check-in |
| Booking method | Online booking is strongly recommended — walk-up availability is not guaranteed |
| Opening days | Open all year except Christmas Day and Boxing Day; off-peak (Oct–Mar) the site is closed on Tuesdays, Wednesdays, and Thursdays |
| Opening hours | 10:00–16:00 daily when open — check the booking calendar for your specific date |
| Cancellation | Tickets are generally non-refundable, so double-check your date before confirming |
| What to wear | Warm, comfortable clothing and trainers or walking boots — some adventures require covered arms and legs |
One thing we’d highlight: opening days vary more than people expect off-peak. Always check the live booking calendar rather than assuming the site is open on your chosen day. Midweek visits in winter need a bit of extra planning!
Getting There, Facilities and On-the-Day Tips
Zip World Llechwedd sits on the edge of Blaenau Ffestiniog in Gwynedd, just off the main road through town. It’s easy to find and well signposted. Here’s what to expect on the day:
Getting there
- By car: On-site parking is available right outside check-in. Parking fees apply, though recent visitors have noted the charge is modest (around £3.40 for the day, payable via the RingGo app). Follow signs to the car park on arrival
- By public transport: Bus and train routes run nearby according to the official Zip World site, though driving or getting a taxi is the more practical option for most families given the location
On-site facilities
The wider Zip World Llechwedd site is well set up for families. You’ll find:
- Toilets and accessible toilets
- Baby changing facilities
- Food and drink on site
- Gift shop
- Free Wi-Fi
- Pushchair-friendly access around the site
- Card payments accepted throughout
On-the-day tips
- Dress for the underground: It’s cooler down in the caverns, so an extra layer is always a good idea even in summer
- Wear the right footwear: Trainers or walking boots are the safest choice — avoid sandals or slip-ons
- Arrive early: The 30-minute check-in window goes quickly, especially with kids to get sorted
- Bring a bag for layers: You may want to stash coats once you’re moving around on the nets!
Final Verdict: Should Families Book Giant Nets?
Bounce Below at Zip World Llechwedd is one of the most memorable family activities in North Wales, and it earns that reputation for good reason. There’s nothing quite like bouncing through a network of giant nets suspended inside a real slate mine — the setting does half the work, and the activity does the rest.
But we’d always rather give you an honest steer than a hype-heavy verdict, so here’s our honest summary:
Our verdict in five points
- Book it if your group is energetic and curious. Bounce Below rewards the kind of families who want to do something, not just see something. If your kids love climbing, jumping, and exploring, this will be a highlight of the trip
- It’s genuinely weather-proof. In a part of Wales where the forecast can change by the hour, having a fully underground activity in your back pocket is genuinely useful. Rain? No problem
- Check the height requirement before you travel. The 1m minimum for Bounce Below means some younger children won’t be able to join in. Confirming this before you make the journey avoids disappointment
- Book the right adventure. The site offers several different experiences, each sold separately. You’re booking Bounce Below specifically — make sure that’s what you want before you confirm
- Book ahead, not on the day. Walk-up availability isn’t guaranteed, and popular dates fill up. Securing your slot in advance is the single biggest thing you can do to make the day run smoothly
