Ynys Seiriol (Puffin Island)

Ynys Seiriol (Puffin Island) sits at the mouth of the Menai Strait opposite Penmon Point, and it’s best thought of as a boat-fishing venue rather than a shore mark. The surrounding waters can fish extremely well for quality species, but access is controlled and conditions can turn hostile quickly.

• Mostly fished from a charter/private boat drifting or anchoring on the surrounding ground
• Renowned for strong tides, rough ground, and sudden changes in sea state
• A highly “situational” venue: brilliant on the right day, unsafe or impractical on the wrong one

Puffin Island lies just off the Anglesey coast by Penmon, guarding the eastern approaches to the Menai Strait. For most anglers the realistic access is by boat; shore access to the island itself is restricted and not a normal angling option.

• Launch/charter access is typically from local slips/harbours on Anglesey or the mainland (use established charter skippers familiar with the area)
• The island is a wildlife site; landing is often controlled and may be prohibited or limited to permit holders
• Even if you can legally land, the shore is largely steep/rocky with exposed faces—boat fishing around the island is the usual and safest approach
• Plan around tide times for the Menai Strait and the east coast; the currents here are the main factor

The mix of tide-swept reefs, kelp edges and nearby sandier patches can hold a wide range of species, with the better fish often coming to those who time drifts and baits precisely.

• Pollack: a headline species here, especially over broken reef/kelp in clearer water
• Wrasse (ballan and corkwing): commonly taken over rough ground on crab or soft plastics
• Mackerel: seasonally abundant, useful for sport and bait
• Cod/whiting: possible in colder months on cleaner edges and adjacent mixed ground (very tide- and year-dependent)
• Rays and flatfish: more likely on nearby sand/mud patches rather than tight to the roughest reef
• Conger eel: can be present around heavier structure and scoured gullies (usually targeted after dark or in deeper water)

This is a venue where you match method to ground: lure-fish the reefs, bait-fish the gullies, and avoid losing gear by working the drift rather than sitting static in snags.

• Drift fishing with shads/jellies, weedless rigs, or metal lures for pollack and mackerel along reef edges
• Light to medium bait fishing for wrasse using crab, mussel, or rag/lug on short, abrasion-resistant traces
• Heavier bottom fishing for conger/codling where appropriate: strong tackle, minimal end gear, and a skipper-led approach to avoid constant snagging
• Float-fishing can work in calmer spells for pollack, presenting baits above the kelp rather than on the deck
• Expect tackle losses on the roughest ground; bring spare leads/lures and consider breakaway links where suitable

The water around Puffin Island is dominated by powerful tidal streams and overfalls, and the fishing is often best when you can control a drift or find a brief slackening. Weather, swell direction and wind-against-tide can transform it from fishable to dangerous.

• Strong currents are normal; many areas only fish comfortably at specific stages of tide
• Overfalls and standing waves can form, especially with swell or wind against tide—route choice matters
• Clearer water often improves lure fishing for pollack; coloured water can suit bait tactics for wrasse and general species
• The most productive drifts are usually along reef/kelp edges and the transitions into slightly cleaner ground
• If you’re not local, rely on skipper knowledge for safe lines and timing

This is not a beginner-friendly mark in terms of seamanship: the hazards are real, and most incidents come from underestimating tide, swell, and the speed at which conditions change. Treat it as an exposed offshore venue even though it’s close to land.

• Boat safety is paramount: lifejackets worn, VHF/communications, and a skipper who knows the overfalls and safe water
• Avoid small craft in wind-against-tide forecasts; conditions can become dangerous very quickly
• Landing on the island is not generally part of angling access and may be restricted; do not assume you can go ashore
• Shore fishing “from the island” is impractical for most anglers due to steep rocks, swell exposure, and limited safe platforms
• Mobile signal can be unreliable; plan accordingly and tell someone your itinerary

There are no angler facilities on Puffin Island itself, and any needs should be handled before you leave the mainland/Anglesey. Treat the trip like a short offshore session.

• No toilets, shelter, shops, or tackle support on the island
• Nearest services are on Anglesey/mainland depending on where you launch or board a charter
• Bring water, food, spare clothing, and seasickness provisions if needed
• Secure storage for gear on the boat is useful—rough ground often means carrying extra terminal tackle

This area rewards tidy, efficient fishing and good boat handling more than brute force. Keep your kit simple, fish just off the bottom where possible, and be ready to switch tactics with the drift speed.

• For pollack, work lures higher in the water column over kelp to reduce snags and draw bigger fish up
• For wrasse, fish crab baits on short traces and keep contact—most bites are decisive, and fish head straight for cover
• Use abrasion-resistant leaders; the ground is unforgiving and fish will rub you off quickly
• Keep a range of lure weights: drift speed can change dramatically through the tide
• If mackerel are thick, use them for fresh strip bait—but keep it legal and within any local bait-collection rules

Puffin Island is a protected wildlife site and access/activities can be subject to restrictions that may change. Sea angling from a boat in surrounding waters is commonly practiced in North Wales, but you should not assume you’re permitted to land or fish from the island itself.

• The island is associated with conservation designations (wildlife/bird interests); landing may require permission and may be prohibited at times
• Check official sources and on-the-day signage/notice boards via local authorities, conservation bodies, or charter operators before planning any shore access
• If using a charter, ask the skipper what is and isn’t allowed around the island and whether any areas are best avoided
• Follow general marine rules: respect other water users, avoid disturbing seabirds/seals, and take all litter home
• If targeting species subject to minimum sizes/limits or local byelaws, confirm current requirements from official Welsh fisheries/byelaw information (do not rely on outdated posts)
