Rathmullan

Beach · Salt water · in The Donegal coast and its sea loughs

A pier and a long sand beach on the western shore of Lough Swilly, with a churned bottom at the first elbow north along the beach that creates the flatfish ground. Sand throughout and strong currents through the lough.

Safety: cliffs and rock platforms — can cause serious injury or death. 3 more points apply here.

What each one does, and what reduces it ↓

FishingHQ describes what this place is, not whether you may fish it. Access, permits and who to ask.

What you can catch here

Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

What these strengths mean
Regular local target
Fishing sources describe this as a normal local target here, not merely as caught.
Recorded here
At least one credible public account of this species being caught here. That is all it means.
How breadth is counted
A fish documented at six marks is shown as six marks: breadth never raises the strength on its own. A fishery account describes the fishing; a recorded catch reports one specific catch. How evidence is weighed.

Recorded here, but not a species to target

These are recorded here, but they are not fish to take. Each is either assessed as Critically Endangered or protected by statute in this jurisdiction, and taking one may be prohibited outright — elsewhere every rod-caught fish must be returned. Read the species page and check the current rules with the authority before fishing.

Fish documented nearby, not here

Nothing below has been documented at Rathmullan itself. Each one has been documented at a named place on the same ground, and the places are listed with it. Treat this as what the water around here holds rather than as a catch list for this mark.

Widely documented on this ground

Documented at three or more neighbouring places, fished a way this place is also fished. That is a pattern about the ground rather than about any one mark, and it is the closest this site comes to saying you will probably meet a fish somewhere nothing has been written about.

One or two accounts each, on the ground around here. Enough to know the fish is caught in these waters; not enough to say anything about this place.

How people fish it

Practised here: Sea fishing.

Methods the sources name for this ground. Each one is explained in full on its own page.

  • Surfcasting

    Casting heavy baited tackle from a beach into surf — a method defined by distance, by tide, and by reading water that all looks the same.

  • Ledgering

    Fishing a bait on the bottom held by a weight, with no float — the simplest way to fish at distance, in depth, or in wind.

  • Spinning

    Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.

Baits and lures for these fish

The baits and lures each of the fish above is commonly taken on, from that fish’s own page. This is what works for the fish, not a report of what people use on this particular water — local knowledge and the conditions on the day still decide.

The ground and the water

The ground
A pier and a long sand beach on the western shore of Lough Swilly, with a churned bottom at the first elbow north along the beach that creates the flatfish ground. Sand throughout and strong currents through the lough.
Exposure
Inside Lough Swilly and sheltered from the Atlantic — one of the sea-lough marks that fishes when the north Donegal coast cannot.
Tide and flow
The directory calls this a very tidal mark needing care with strong currents, and says both low tide and the flood are productive. Waders are needed to reach the elbow on the beach.

Through the year

Tope and ray in summer, mackerel in summer, and the flatfish ground working through the year.

The months the sources attach to each species here. Where a species carries no season it is listed underneath rather than assumed to run through the year.

Safety

Cliffs and rock platforms — Can cause serious injury or death

Long-period ground swell generated by storms in the open North Atlantic arrives with its energy intact and independently of local wind, so a rock platform can be taking sets that arrive without warning under a blue sky and a flat forecast. The marks with deep water close in are the most attractive and the most exposed, and this is how people are swept off this coast.

What reduces it: Read the swell forecast — period as well as height — rather than the wind forecast. Watch any platform through several full set cycles before committing to it, and pick a position you could leave immediately. Deciding not to fish a mark is routine here rather than cautious.

Fishing alone — Can cause serious injury or death

Much of this coast is remote, has no mobile coverage and is a long way from help, so an ordinary injury — a turned ankle on broken rock, a fall on a wet slope — becomes a serious problem because nobody is coming and nobody knows where to look.

What reduces it: Tell somebody the mark and the return time. Carry a means of calling for help that does not assume mobile coverage. Do not fish exposed rock alone.

Slips, trips and falls — Can cause serious injury or death

Wet rock, weed-covered ledges, boulder shores and steep descents to the water. Falls here produce broken ankles and head injuries, and they happen on the walk rather than in the fishing.

What reduces it: Boots with a stiff sole and real grip, both hands free on a descent, and a route down chosen in daylight if the session runs into darkness.

Cold water shock — Can cause serious injury or death

General safety for this kind of ground, not a finding about this place.

UK coastal and inland water is cold enough for most of the year to trigger the involuntary gasp and the loss of swimming ability that decides most immersion deaths, and it does so within the first minute, long before hypothermia is relevant.

What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person rather than in a bag, and plan on the assumption that an unplanned entry into the water is survivable only if somebody knows immediately.

Rules and access

FishingHQ does not know the current access position here. Sea angling in Ireland is not generally licensed, but access rights, landowner permission, harbour and local authority rules, conservation designations and national fisheries measures all apply and all change. Check the current position with Inland Fisheries Ireland, the harbour or local authority and the landowner before going.

Who holds the answer:

  • Inland Fisheries Ireland, which administers angling and fisheries protection.
  • The harbour or local authority, for access to structures and the shore.
  • Inland Fisheries Ireland, for freshwater fisheries, for salmon and sea trout licensing and tagging, and for the sea angling conservation measures it administers.
  • The government department responsible for the marine, and the Sea-Fisheries Protection Authority, for sea fisheries measures, minimum sizes, bag limits and protected species.
  • The National Parks and Wildlife Service, where a designation constrains access, disturbance or collection.
  • The Food Safety Authority of Ireland and the shellfish classification and biotoxin monitoring programme, before anything filter-feeding is taken.
  • The harbour authority, local authority, club or landowner controlling the specific structure or shore, whose permission is theirs to give and is not stated here.
  • The Irish Coast Guard and the RNLI, for safety guidance on this coast.

Positions are approximate by design — they are capped at about a hundred metres and describe where a named public place is, not where fish are and not a mark.
