Llanddwyn Bay

Llanddwyn Bay is a long, scenic sweep of sand on the south‑west coast of Anglesey, best known for its clean surf and the shelter it can offer compared with the more exposed headlands nearby.

• • It’s primarily a surf mark where conditions dictate everything: in a good swell it can fish very well for bass and flatties, while in flat-calm, gin‑clear water it can be harder work.
• • Expect a lot of ground to explore; success often comes from locating gullies, small scours and any colour in the water rather than sitting in one spot.
• • This is also a popular recreational beach and sits within a sensitive dune/coastal environment, so anglers need to be especially considerate.

Llanddwyn Bay fronts Newborough Warren and the approach to Llanddwyn Island (Ynys Llanddwyn), with access typically from the Newborough forest/warren side and then a walk across dunes/paths to the beach.

• • Access is on foot for the last section; be prepared for a fairly long walk depending on where you park and which part of the bay you plan to fish.
• • The beach is expansive, so you can usually find quieter water away from the main family areas by walking further along the bay.
• • After heavy weather, some dune paths can be soft or blown with sand; good footwear makes a big difference.
• • If you’re carrying a lot of tackle, consider travelling light and mobile rather than setting up a “static” camp.

This is a classic mixed surf mark, with target species changing through the seasons and with sea state.

• • Bass: the headline species, especially when there’s a bit of surf, colour and a gentle onshore push.
• • Flatfish: flounder and plaice can show in the cleaner, calmer spells; dabs/other small flats may feature depending on conditions.
• • Whiting: can appear in the colder months, especially at dusk into darkness.
• • Dogfish: possible in some conditions, particularly after dark with fish baits.
• • Occasional surprises: sea trout can travel this coastline; if present they’re usually best approached with lures at low light and in calm/settled conditions (where permitted and safe).

Llanddwyn Bay rewards anglers who fish the features rather than the “middle” of the beach, and who match bait/lure choice to water clarity.

• • Surfcasting with clipped‑down rigs is useful when you need distance across a flat profile; step up weight only as needed to hold bottom in surf.
• • For bass in a swell: fish a simple running ledger or pulley pennel with fresh, oily baits; keep hook sizes sensible for the bait and expected stamp.
• • For flounder/plaice: a 2–3 hook flapper with beads/attractors can score in clearer water; smaller baits fished neatly often outfish big offerings.
• • Lure fishing (when conditions allow): metals, soft plastics and shallow divers can work best at dawn/dusk on a flooding tide; cover ground and work the edges of gullies.
• • Mobility is key: move until you find a gully, a rip line, a patch of colour, or feeding birds; then work that area thoroughly.
• • In bright, clear conditions: scale down, lengthen traces, and fish low‑scent baits or subtle lures; in coloured water: increase scent and profile.

The bay can fish on many stages of the tide, but the best sessions usually coincide with moving water and some sea state.

• • Best general window: the flood tide into early ebb, particularly when surf and colour are present.
• • Low water: use it to read the ground—note gullies, runnels and any deeper cuts that will fill first on the flood.
• • Surf and colour: a moderate swell with a bit of “tea” in the water often improves bass chances and brings fish closer.
• • Very calm/clear seas: fishing can be slower; focus on flatties, low-light periods, and subtle presentations.
• • Wind: a light to moderate onshore can help; strong onshore makes casting and bite detection difficult and can create hazardous surf.
• • Weed: after storms, drifting weed can be an issue—carry a few different rigs and consider heavier leads or shorter hooklengths if you’re constantly fouling.

This is a large, open beach environment where conditions can change quickly, and the long walk in/out needs factoring into your plan.

• • Tide awareness: avoid being cut off if you roam toward the island/ends of the bay; keep an eye on the turning tide and plan your return route.
• • Surf safety: heavy swell and shore dump can be dangerous—keep well back from the waterline and never turn your back on waves.
• • Soft sand and dunes: walking can be tiring; travel light, take water, and allow extra time for the hike back.
• • Night fishing: use a headtorch plus spare, mark your exit points in daylight if possible, and be cautious around any scours/runnels.
• • Weather exposure: little shelter on the beach—windproof layers are essential even in summer evenings.
• • Accessibility: the dunes/soft sand make it challenging for those with limited mobility; check local access options and current path conditions before committing.

Facilities depend on where you access the bay from, and they can be seasonal.

• • Parking is typically available in the wider Newborough/forest area (arrangements can vary), but expect a walk from the car to the shore.
• • Toilets/cafés are more likely near main access points and during busier months; do not assume they’ll be open late or in winter.
• • No tackle shop on the beach itself—bring spare leads, rigs, and enough bait for the session.
• • Mobile signal can be variable; let someone know your plan, especially for night sessions.

A bit of local watercraft goes a long way here—small changes in depth and colour can concentrate fish along a seemingly featureless shoreline.

• • Spend the first 15 minutes walking and watching: look for deeper, darker lanes, rip lines, and any area where waves “stand up” then flatten (often a gully).
• • If you find a gully: fish the near edge first, then the far edge; bites often come as the tide begins to push through.
• • Bass often patrol tight in—don’t automatically cast to the horizon; fish at varied ranges and keep a rod ready for close work.
• • Match bait to conditions: big, smelly baits in coloured surf; smaller, neater baits in clear water.
• • Be courteous to other beach users and give swimmers/dog walkers wide berth; moving a short distance can transform both your fishing and everyone’s experience.
• • Leave no trace: take line clippings and bait packaging home—this area is valued for its wildlife and natural beauty.

Llanddwyn Bay sits within a highly sensitive coastal landscape associated with Newborough Warren and Ynys Llanddwyn, and some areas can have specific rules or seasonal restrictions.

• • Fishing is not clearly and universally banned across the whole bay, but local restrictions may apply in certain zones (for example, wildlife protection areas or managed sections of the beach).
• • Access/parking controls may be in place via local land managers; always follow on‑site signage and any staff instructions.
• • Check for any byelaws or notices relating to protected habitats, dog controls, fires/barbecues, and night access—rules can change.
• • Observe national and local best practice: respect minimum sizes where applicable, consider voluntary catch-and-release for bass, and handle all fish carefully.
• • If in doubt, consult official on-site notices and the relevant local authority/land management body before fishing, especially if targeting near sensitive areas or during peak wildlife seasons.
