Traeth Coch

Traeth Coch (Anglesey) is a broad, sheltered bay with a big tidal range and extensive sand/mud flats that can fish well for classic inshore species when you time it right. It’s more of a “tides and conditions” mark than a snaggy rough-ground venue, with sport often improving after dark and around moving water.

• Best thought of as a mixed flatfish/roundfish bay where wind direction, water clarity and tidal timing make a huge difference
• Productive sessions typically come from fishing the channels and the edge of the main flow rather than casting onto featureless flats
• Because it’s a shallow, draining bay, planning for access and safe exit matters as much as rig choice

Traeth Coch sits on the east/south-east side of Anglesey and forms a long, gently curving beach backed by dunes/low ground, with tidal flats extending a long way out. Access is usually straightforward, but your actual fishing position will change dramatically with the tide.

• Expect a long walk at low water: the sea can be a very long way out and the “good water” may be confined to channels
• Most anglers fish from the beach itself or by moving to firmer sand nearer the water line as the tide pushes in
• After heavy rain or on very big tides, some access points can become soft underfoot—treat any muddy sections with caution
• If you’re visiting for the first time, arrive early on a daylight tide to learn where the channels sit before attempting a night session

This is a mainly sandy/shallow-bay venue where flatfish and smaller roundfish are the bread-and-butter, with occasional better fish when conditions line up. Species presence varies seasonally and with water temperature, and some years are noticeably better than others.

• Flatfish: flounder are the most reliable, with plaice and dab possible when the bay has clean water and good sandeel/food movement
• Roundfish: school bass can show, especially when there’s a bit of colour and food being pushed in; whiting can feature in colder months
• Other possibilities: dogfish and the odd ray can turn up, particularly where the bay meets deeper water or stronger tidal flow
• Expect quality to be tide-dependent rather than “anytime”; blanking is common if you fish slack water over featureless ground

Traeth Coch rewards simple, clean presentations and good bait choice, with the key being to locate the run of water and fish the edges of it. Because the seabed is mostly sand/mud, you can fish lighter and cleaner than on rough ground.

• General approach: 2-hook clipped-down flapper or a simple pulley/dropped paternoster to present baits neatly at range
• Flatfish tactics: longer traces and smaller hooks can help for flounder/plaice; keep baits tidy and avoid overly bulky cocktails
• Bass tactics: fish a single hook pulley or running ledger with larger baits when there’s a bit of surf or coloured water
• Baits: ragworm/lugworm are prime for flounder and general fishing; peeler crab can be excellent for bass when available; small fish baits can pick up whiting/dogfish
• Casting and positioning: don’t just “hit it hard and hope”—fan casts to find channels/firm sand, then repeat the productive line
• Bite detection: in calmer conditions, use a more sensitive setup and keep lines tight enough to read small flatfish taps

This is a big-tide venue where timing is everything: you generally want moving water, and the best feeding often coincides with the tide pushing cleanly into the bay or draining back through channels. Wind direction and swell can either make it fish well or kill it completely.

• Tide stage: fish the flood to get closer access to depth; the ebb can fish if you’re positioned on the outflow of a channel
• Springs vs neaps: springs create stronger flow and more pronounced channels but can also expose more soft ground—neaps can be easier/safer but sometimes less “push”
• Water clarity: a slight tinge of colour is often ideal; gin-clear calm water can make fish cautious in the shallows
• Wind: onshore breezes can improve sport by stirring food; strong winds can make presentation difficult and increase the risk of being cut off
• Night vs day: night sessions commonly improve bass and general confidence feeding; daylight can still be good for flounder, especially in winter and early spring
• After storms: new sand movement can reshape channels—recheck the beach rather than assuming last trip’s features remain

Traeth Coch can look benign, but the main hazards are the speed and distance of the tide, soft mud/sand, and being tempted to follow fishable water too far out. Treat it as an estuary-style bay where you plan your exit before you cast.

• Tidal safety: the tide can advance quickly across shallow flats and cut off return routes—set a firm “turn back” time
• Ground conditions: soft mud and gullies can be present, especially near channel edges; avoid wading unless you know the ground well
• Night fishing: only attempt after you’ve learned the beach layout in daylight; use a headtorch plus spare and mark your exit line
• Weather: strong onshore winds and swell can make it unsafe to fish low down the beach; step back and fish higher if needed
• Accessibility: the beach itself is generally easy walking on firm sand, but longer low-tide walks and soft patches can be challenging
• Respect other users: it’s often used by walkers and dog owners—cast safely and keep gear tidy

Facilities depend on the specific access point you choose and the time of year, with the area generally being more “natural beach” than fully serviced seafront. Plan to be self-sufficient, especially for night sessions.

• Take what you need: bait, water, warm layers and a basic first-aid kit—there may be limited options nearby at unsociable hours
• Parking is typically close to the beach at common entry points, but capacity can vary in peak periods
• Mobile signal can be variable around coastal dips—don’t rely on it as your only safety plan
• Leave no trace: take line, bait packaging and food waste home

Traeth Coch often fishes best for anglers who treat it like a feature-finding exercise rather than a “park-and-cast” beach. Small tweaks to where you stand and how you present baits can change the result completely.

• Walk the beach on a low tide first and note channels, firmer sand bars and any obvious run of water for your next flood-tide session
• If bites are scarce, shorten the range and fish the nearer channel edge—fish often patrol surprisingly close in on the flood
• Keep baits fresh and streamlined; over-large cocktails can reduce takes on a shallow, clear-water bay
• When targeting bass, fish the period when the tide first brings depth back over the flats and food starts moving
• In colder months, flounder can be consistent—fish worm baits and concentrate on gutters rather than the open flat

I’m not aware of a blanket, always-in-force ban on angling at Traeth Coch, but coastal access can include seasonal restrictions, protected habitats and local byelaws that may affect where and how you can fish. Treat any signage on-site as definitive and check official sources if you’re unsure.

• Check for local notices: look for signs relating to protected birds/habitats, temporary exclusions or access limitations
• Byelaws may apply: rules on bait collection, size limits and fishing methods can change—verify with the relevant Welsh fisheries authority and local signage
• Respect private land and access routes: use public paths/entries and do not block gates or driveways
• If you plan to gather bait (e.g., digging), confirm it’s permitted in that specific area and follow any restrictions
• Practice good fish care and comply with any current guidance on bass and other regulated species (check the latest official updates before you go)
