We’ll be straight with you: Gwynedd has exactly one listed secure, private-hire dog field, and we checked thoroughly before settling on that number — all ten pages of British Dog Fields’ Wales listings, plus dogwalkingfields.co.uk’s and wagglytails.com’s own Wales searches directly. Nothing else came up anywhere in the county.
- Traws Dog Park, Ty Llwyd Farm, Trawsfynydd, LL41 4TH — from £5 for 30 minutes, listed as 1-2 acres (though the field’s own listing separately marks its size as “TBC,” an inconsistency on their own page), fencing 5ft to just under 6ft, described as mixed drystone wall and stock fencing. Maximum 6 dogs, booking online or by phone (07908 430566). This is a single-field site with no customer buffer stated, which suggests but doesn’t explicitly confirm sole use.
A clear caveat: we could not independently corroborate this listing anywhere. There are no reviews on its own aggregator page, no independent directory cross-listing, and no press or forum mention we could find. It’s the only name on offer for the whole county, so we’re including it, but we’d treat the size and sole-use claims as the operator’s own word rather than independently confirmed, and we’d suggest a phone call before booking if either detail matters to you.
Honest summary: coverage across Gwynedd is essentially empty outside Trawsfynydd. There is nothing confirmed anywhere near Bangor, Caernarfon, Pwllheli, Porthmadog, Dolgellau, Barmouth, Harlech, Bala, Abersoch, Criccieth or Tywyn, and the entire Llŷn Peninsula and coastal strip has no secure field listed on any of the three directories we checked. If you’re on the coast or the peninsula, the nearest option is likely to be a genuine drive.

A secure field is one of the best options for a reactive or nervous dog who needs proper off-lead time without the worry of livestock or other dogs. If yours is still a bit wound up even alone in a field, a calming bite beforehand can help, alongside whatever training you’re already doing. Persistent reactivity is worth discussing with your vet or a qualified behaviourist.
Frequently Asked Questions
Is there a secure dog field in Gwynedd?
Just one that we could find: Traws Dog Park in Trawsfynydd. We checked thoroughly across all three main UK secure-field directories and found nothing else in the county.
Is Traws Dog Park guaranteed sole use?
It’s not stated explicitly. The listing describes it as a single-field site with no buffer between bookings, which implies sole use without confirming it outright — worth checking directly if that matters for your dog.
Is there a secure dog field on the Llŷn Peninsula?
Not one we could find. The whole Llŷn Peninsula and Gwynedd’s coastal strip currently have no secure dog field listed on any of the directories we checked.
