Why this window?
Silver Bay (Traeth Llydan) is a broad, gently shelving sandy bay on the Rhosneigr side of Anglesey, fished mainly as a clean-ground surf beach with occasional broken patches toward the edges. Access is straightforward via Rhosneigr/Silver Bay parking and a short walk over dunes/paths to the sand; anglers typically spread out and fish at range on a rising tide. It’s a classic ‘cast-and-wait’ mark for flatfish and school species, with the best sport around dusk/dark and on spring tides when the bay fills and fish move in.

Silver Bay fishing guide
Silver Bay on Anglesey (the broad, sandy bay at Rhoscolyn) is a user-friendly shore mark best known for mixed species and its consistent opportunities for bass and flatfish.
- Wide, gently shelving sand with scattered rock and weed at the fringes gives you several “micro-marks” in one bay.
- It can fish well for both bait anglers and light lure anglers, but results are tide- and water-clarity dependent.
- Popular with walkers and beach users in season, so timing and considerate casting matter.
- Expect the fishing to be straightforward, but the sea and rocks can become hazardous when swell pushes in.
Silver Bay sits on the south-west side of Anglesey by Rhoscolyn, with access typically via local lanes and a walk down to the beach.
- Access is generally via the main beach path; some approaches include steps and uneven sections that can be slippery after rain.
- The best fishing areas are spread across the bay: central sand for flatfish, and the edges/nearby rock for bass, wrasse and pollack.
- It’s a relatively easy mark compared with many Anglesey rock venues, but you still need to plan for the walk back on a rising tide.
- In summer the beach is busy; fish early/late to avoid casting near swimmers and paddleboarders.
Silver Bay offers classic Anglesey mixed-bag fishing, with the emphasis changing through the year and with sea conditions.
- Bass: often the headline species, especially in low light, over broken ground and along the surf line.
- Flatfish: flounder, dabs and plaice can show on clean sand, particularly when there’s some colour in the water.
- Wrasse: around rocky edges and kelp in settled conditions (best with rough ground tactics).
- Pollack: possible around rockier corners and deeper gullies, especially on lures.
- Dogfish and small rays: can turn up, more likely when you’re presenting baits on the sand.
- Mackerel: occasional from rocky edges when shoals move close, generally better at more exposed marks but worth trying in summer.
This is a versatile mark: fish the clean sand for flatfish and the edges/broken ground for bass and wrasse, adjusting rigs to match snags and surf.
- Beach/flatfish approach: 2-hook flapper or pulley/pennel style rig with a light grip lead; cast to the edge of the surf or into any subtle gutters.
- Bass on bait: simple pulley rig or a clipped down 1-up/2-up with a single larger hook to reduce tangles in surf; fish fresh lug/rag or crab where ground allows.
- Bass on lures: small soft plastics, sandeels and shallow divers worked across the surf line and along rocky edges at dawn/dusk.
- Wrasse tactics: short-range fishing into kelp/rock with strong tackle; float-fished rag or crab can be effective where safe and permitted.
- Bait choice: lug and rag for general fishing; crab and mussel can excel around rough ground; keep baits fresh and present them neatly.
- Casting advice: the bay can reward modest casts—focus on finding structure (gutters, patches of rough, colour changes) rather than simply hitting distance.
Silver Bay is strongly influenced by tide height, water clarity and swell; the best sessions usually come when you match your approach to the sea state.
- Tide: many anglers do well on the flood and around high water when fish move in over the shallows; ebb can still produce if there are gutters holding water.
- Sea state: a slight chop or a bit of colour can switch the beach on for bass and flatfish; very clear, calm water can make fish wary in daylight.
- Wind: onshore or quartering winds can help create a surf line and colour; strong onshore winds can make it uncomfortable and unsafe.
- Swell: even when the beach looks manageable, bigger swell can make rocky edges hazardous—choose the sand if there’s any doubt.
- Light levels: early morning, dusk and night are prime times for bass, especially in summer and early autumn.
The central sandy areas are comparatively safe by Anglesey standards, but the surrounding rock and the bay’s exposure mean you still need to treat it as a serious coastal venue.
- Slips and trips: wet rock and seaweed are extremely slippery—use proper footwear and avoid scrambling when there’s swell.
- Tide cut-off: some rocky sections and shortcuts can become awkward or cut off—always keep an exit route in mind.
- Surf hazards: strong waves and backwash can knock you off balance; keep well back from the lip and never turn your back on the sea.
- Night fishing: bring a headtorch, spare light, and fish with a buddy if possible; keep gear organised to avoid falls.
- Accessibility: the main beach approach is easier than many cliff marks, but uneven paths/steps may not suit all mobility levels; check conditions before committing.
Facilities are limited at the mark itself, so it pays to arrive prepared and be self-sufficient.
- Parking: typically available near the beach access, but spaces can fill quickly in peak season.
- Toilets/shops: not guaranteed at the beach—plan to use facilities in nearby villages/towns before you arrive.
- Mobile signal: can be variable around coastal angles and dips; don’t rely on it for safety.
- Shelter: very little natural shelter on the open beach; bring suitable clothing for wind and showers.
- Rubbish: take everything home, including bait packaging and line offcuts.
Silver Bay rewards anglers who treat it like several marks in one: read the water, move, and match your rig to the ground.
- Work the transitions: fish where sand meets scattered rock/weed—these edges often hold bass and better-quality fish.
- Look for gutters: at lower stages of the tide, identify deeper runnels and aim to fish them as the flood fills.
- Keep it tidy in surf: clipped-down rigs and streamlined baits reduce tangles when there’s wave action.
- Be considerate: in summer, fish early/late and cast well away from beach users; avoid leaving rods unattended.
- Scale tackle to conditions: lighter leads and longer traces can help in calm conditions; step up to grip leads and stiffer rods when the surf builds.
- Move if it’s quiet: a short shift toward a rockier corner or back to clean sand can make a big difference.
There is no single, widely published blanket ban specific to “Silver Bay” that can be relied upon without checking locally, but coastal access and fishing activity can be affected by local rules, conservation measures and seasonal sensitivities.
- Check for signage at access points regarding beach byelaws, dog restrictions, or any temporary safety notices that could affect where/when you can fish.
- If you plan to target bass or use particular methods, follow current Welsh and UK sea angling rules and any applicable limits; these can change, so verify via official sources.
- Some nearby coastal areas in Wales have conservation designations—these don’t always prohibit angling, but they may influence what you can do (e.g., bait collection, access, or protected features).
- Use only permitted access routes and avoid causing damage to dunes/vegetation; responsible conduct reduces conflict and helps keep access open.
- If in doubt, confirm locally (harbour/visitor information, council notices, or on-site signs) before fishing.
