The lagoon

Lough Gill

Lough Gill, Castlegregory, Co. Kerry

Lough Gill is a shallow coastal lagoon on the western edge of the village, at the base of the Maharees. It is roughly two and a half kilometres long, it averages barely a foot deep, and a sluice holds its level and lets the outflow away into Tralee Bay. That arrangement keeps most of the salt out while leaving the water faintly brackish, which is why it holds freshwater species alongside lagoon specialists: beaked tasselweed, horned pondweed, fringing reed and club-rushes, and the rare stonewort Chara canescens.

The shallow, warm, gently shelving margins are exactly what natterjack toads need to spawn, and this is one of the country's most important breeding sites. The National Parks and Wildlife Service records tadpoles here in the tens of thousands, and found a new breeding site on the north shore during its last survey. To be precise about a claim that is often overstated: it is the wider Special Area of Conservation that holds the largest natterjack population in Ireland, and possibly in Britain and Ireland, with the Maharees and the golf course returning more egg strings than the lough itself.

In winter the interest changes completely. The wider site is an internationally important wetland for wintering waders and wildfowl, with whooper swan, golden plover and bar-tailed godwit in nationally important numbers, and chough feeding on the dunes.

Good to know

We want to be straightforward about access: we could find no official source describing a visitor path, a hide, a boardwalk or a car park at Lough Gill. Much of the shore is farmland, and the golf club holds the ground between the lough and Brandon Bay, which is private. Ask at the information centre on Tailor's Row before you set out.

The natterjack is protected under the Wildlife Act and is Red-listed as Endangered. Handling or disturbing toads, spawn or tadpoles is an offence, not a matter of etiquette. The spawn sits in very shallow water at the margin, which is precisely where a person or a dog would wade, so stay out of the shallows between April and July and keep dogs close.

The famous rasping chorus is a spring event. Do not come in August expecting to hear it.

How we checked. Designations, habitat and survey figures from National Parks and Wildlife Service site synopses and its natterjack monitoring report IWM107. Opening hours and prices on this coast change without notice, so ring before you travel. If anything here is wrong, tell us and we will fix it.
