Cable Bay (Porth Trecastell) is a small, sheltered sandy cove with rocky edges and scattered weed-covered boulders, giving mixed ground fishing at short range. Access is easy via the coastal path and nearby parking, then a short walk onto the sand or rocks; it’s a useful venue when the open coast is rough. Expect clean sand for flatfish and rays in the bay, with wrasse, pollack and occasional conger tight to the kelpy fringes and rockier sides.

Cable Bay fishing guide

Cable Bay on Anglesey is a small, sheltered sandy bay with rocky edges that can fish well for a mix of close‑range species, especially when there’s a bit of surf or coloured water. It’s not a “big-cast” venue so much as a mark for working features—gut, corner rocks, and any kelp line—methodically.

  • Best thought of as a light-to-medium tackle beach mark with reef influence at the sides
  • Can produce quick sport in the right conditions, but it’s often condition-dependent (swell, weed, clarity)
  • Ideal for anglers who enjoy reading water: seams, channels, and any darker patches of mixed ground

Cable Bay sits on the north coast of Anglesey and is reached via local roads to the small beach area, then a short walk onto sand. Access is generally straightforward in calm weather, but the bay’s corners and any rock platforms require care.

  • Access is typically via public coastal approaches and the beach itself; expect a short walk-in from nearby parking areas
  • The main fishing is from sand with opportunities from rocky corners/edges depending on tide and sea state
  • After heavy rain, paths and grassy approaches can be slippery, and sand can be soft in places

Cable Bay’s mixed habitat—sand with nearby rock/weed—means you’re fishing for classic inshore species rather than deep-water specialists. Catches vary a lot with season, water clarity, and whether surf is running.

  • Bass: often the headline target, especially with surf, dusk/dawn, and around the bay edges
  • Flounder (and occasional other flatfish): best in calmer conditions and when you can find a trough/gutter
  • Dogfish: common after dark, particularly when a bit of scent is in the water
  • Wrasse: more likely if you work the rocky edges with appropriate tactics
  • Mackerel: possible when shoals push in close in summer, mainly on lures/feathers from the rockier areas
  • Pollack/coalfish: occasional from rougher ground when conditions suit (more likely around structure)

This is a mark where presentation and placing a bait into the right feature usually beats brute distance. Adjust your approach depending on whether you’re fishing clean sand or bringing the rocky edges into play.

  • Bottom fishing (beach): keep it simple with a running ledger or short snood paternoster for flounder, dogfish and general species
  • Bass bait tactics: fish a single hook, streamlined rig into any gutter/edge; in surf, a slightly longer snood can help bait movement
  • Lure fishing: work soft plastics, minnows, or small metal lures along the edges and any rip line for bass/pollack/mackerel
  • Float/ledger near rocks: for wrasse, fish close to structure with a robust hooklength and be ready to steer fish away from kelp
  • Baits that commonly score: lugworm, ragworm, crab (where appropriate), sandeel, and fish baits for dogfish—match bait to target and conditions
  • Tackle balance: medium surf rods are fine for bait work; a spinning setup covers most lure opportunities without overkill

Cable Bay is sensitive to sea state: a little swell and colour can switch it on, while heavy weed or a big blow can make it hard work. Tide height changes how much of the bay fishes and whether the rocky edges are usable.

  • Best conditions for bass: light-to-moderate surf, coloured water, and low light (dawn/dusk/night)
  • Best conditions for flatfish: calmer seas with a defined gutter/trough and manageable drift
  • Tide planning: explore on a low tide to map gutters and hard patches, then fish those lines as the tide floods
  • Weed factor: after prolonged swell or certain wind directions, expect weed and kelp to collect—scale down rigs or switch to cleaner areas
  • Wind: onshore winds can build surf and colour quickly; strong crosswinds can make bait presentation and line control difficult

It’s a relatively sheltered venue by Anglesey standards, but the usual North Wales coastal hazards still apply—especially around wet rock, swell, and rising tides. The beach itself is the safest option in most conditions.

  • Rocks: treat the corners and any ledges with caution—wet algae and sudden swell can be dangerous
  • Tide cut-off: avoid pushing too far around corners on a rising tide; plan an exit route before committing
  • Night fishing: use a headtorch and keep a clear line of retreat; avoid unfamiliar rock ground in the dark
  • Surf safety: even small surf can knock you off balance when wading—there’s rarely a need to wade far here
  • Accessibility: the beach is generally easier than rock marks, but surfaces can be uneven and soft underfoot

Facilities are limited and depend on the immediate access point and season. Plan as if you’ll be self-sufficient for bait, food, and basic needs.

  • Limited on-site amenities; bring water, spare tackle, and a basic first-aid kit
  • Parking is typically nearby but can be tight in good weather—arrive early when possible
  • Mobile signal can be variable along parts of the Anglesey coast; let someone know your plan if fishing late

Cable Bay rewards anglers who keep mobile and fish the features rather than sitting in one spot for hours. Spend time watching the water before you cast and you’ll usually find the most productive line.

  • Work the seams and darker water where the sand meets broken ground—predators patrol these edges
  • If bites are scarce, move 20–30 yards and re-check depth: a small gutter can hold most of the fish in the bay
  • In weedy conditions, shorten traces and use more streamlined leads to reduce snagging and weed build-up
  • For bass, prioritise low light and a bit of surf; for flounder, go for cleaner water and steady bait presentation
  • Keep tackle losses down by learning where the rough ground starts—fish “just off” it rather than directly in it until you’ve mapped it

There’s no widely publicised, single blanket ban that clearly applies to “Cable Bay” as a named angling mark, but local restrictions can exist due to conservation, access rules, or temporary signage. Treat this as a check-before-you-fish venue and follow local guidance on the day.

  • Check for local signage at access points regarding permitted activities, seasonal restrictions, or protected areas
  • Anglesey has sensitive coastal habitats—avoid damaging dunes, vegetation, and rockpool life, and take litter and discarded line home
  • If targeting bass, ensure you follow current Welsh/UK rules (sizes, limits, methods); regulations can change, so verify with official sources
  • Be mindful of other beach users and keep rods and lines clear of swimmers, paddlers, and dogs, especially in summer
