Monmouthshire and Brecon Canal

Fancy a canal session rather than a lake complex? This stretch of the Monmouthshire and Brecon Canal is managed by Merthyr Tydfil Angling Alliance, usually shortened to MTAA. Its fishing runs from Brecon theatre basin to Bridge 153 at Pencelli. That’s the venue to keep in mind: a managed length of canal, not just the water around the basin and certainly not a collection of separate fishing lakes.

• 1 lake: Brecon theatre basin to Bridge 153 at Pencelli
• Fish: roach, chub, perch, eel, bream, carp, pike
• Tickets from: Canal-only membership — all ages, 12 months from purchase — £20

Fancy a canal session rather than a lake complex? This stretch of the Monmouthshire and Brecon Canal is managed by Merthyr Tydfil Angling Alliance, usually shortened to MTAA. Its fishing runs from Brecon theatre basin to Bridge 153 at Pencelli. That’s the venue to keep in mind: a managed length of canal, not just the water around the basin and certainly not a collection of separate fishing lakes.

There’s a cracking mix of coarse species to make things interesting. Roach, dace, chub, perch and eels are listed as common, with skimmer bream, occasional carp and pike also reported. That gives this place more of a mixed-bag identity than a dedicated carp-water feel. If your whole plan revolves around chasing lumps, note that word ‘occasional’. The attraction here is the variety, rather than any published promise of big carp.

The ticket setup deserves a proper look before you pack the tackle. Canal-only membership costs £20 for all ages and lasts 12 months from purchase. Adult canal guest tickets cost £3.50 per day, while junior canal guest tickets cost £2 per day. The important catch is that guest-ticket anglers must be guested by a full MTAA member. Don’t mistake those prices for an unrestricted turn-up-and-fish day ticket available to anyone.

There’s also a £30 weekly permit covering Brecon Canal alongside Dolygaer/Pontsticill Reservoirs, Top/Middle Ponds Penywern and Cyfarthfa Lake. Whichever relevant permit you arrange, get it sorted before fishing: tickets aren’t sold at the venue. Membership can be bought online by credit or debit card, and online members can book guest tickets through their club account. A little planning before leaving home saves a fair bit of faff when you reach the bank.

Fishing is available all year round, though daily opening and closing hours aren’t specified. Night fishing is a separate question, so check with MTAA rather than treating year-round access as permission for an overnight session. The basin and boat-mooring areas can be busy from Easter to early September. During the main boating season, you must avoid fishing near occupied moorings or opposite marina entrances. Picking a swim means considering boat activity as well as fish.

At the Brecon end, a pay-and-display car park serves the basin, with toilets in the theatre and town centre. The postcode points to Canal Wharf at Brecon Basin, and the coordinates identify the basin rather than the whole fishing length. Once you’re fishing, it’s towpath side only, with barbless hooks required. Keep clear of locks, movable bridges and signed overhead-line exclusion zones, and leave residents’ access unobstructed. Straightforward canal manners, with some important boundaries to get bob on.

Good background reading. Most of it is a few years old, so treat it as a starting point and ask on the day.
