Derrymore Island – a salt-marsh spit

📍 Derrymore, Kerry

🏛️ Attraction

Last updated: 29 June 2026

Overview

Derrymore Island is a compound spit – a long finger of pebble beaches and salt marsh reaching out into Tralee Bay – on the Dingle Peninsula, about 11 km west of Tralee. The National Parks and Wildlife Service rates it one of the best spits in Ireland and runs it as a nature reserve for its rare salt-marsh plant communities. The Irish name Doire Mór means ‘big oak wood’, a reminder of the native woodland that once stood here before the sea reshaped the land into low wetland.

Be honest with yourself about why you’re going. The real draw is the birds and the geography, not a dramatic view. If you’re a birdwatcher, this is a genuine reason to detour off the N86; if you just want sand, the strand alongside it does the job without the tide-watching.

Birdwatching and wildlife

The spit is at its best for birds. Wigeon and brent geese graze the salt marsh along its eastern side, and when the tide comes up and the pebble beaches go under, the white top of the spit becomes an important high-tide roost for waders. Spring and autumn migration are the busy windows; bring binoculars, keep low and keep your distance, and you’ll see more.

Since 2008 the NPWS has run a habitat-creation scheme here for a rare amphibian, almost certainly the natterjack toad, Ireland’s only toad and a Kerry specialist. Seals and dolphins turn up in the wider bay more often than on the spit itself.

Walking the spit

Getting onto Derrymore Island is entirely tide-dependent. At low water a firm sand-and-pebble causeway links the mainland to the reserve and you can walk the full length of it; as the tide turns, that route closes. The ground is flat but uneven, with loose shingle and tidal channels cutting through the marsh grass, so waterproof boots earn their keep.

The walk gives you Tralee Bay’s calm water on one side and the open Atlantic on the other, framed by Baurtregaum and Caherconree in the Slieve Mish range. Botanists will spot the clear zonation of salt-tolerant plants, from the bright green near the waterline to the tougher grey-green grasses inland.

Practical information

Access and timing
Like other NPWS reserves, the island is open access and free to enter, but the visit lives or dies by the tide. The causeway is only safe at low water, so check a Tralee Bay tide table and aim to arrive an hour or so before low tide to give yourself time on the spit. Access is via a tight country lane branching about 1 km off the N86. The car park holds roughly 30 cars and fills on fine weekends.

What to bring
There are no facilities at all – no toilets, no café, no power, no bins. Bring water, snacks, a rain jacket and sturdy waterproof footwear, and take all your litter home.

Conservation
This is a protected reserve. Keep dogs on a short lead, stay on the walking routes to spare the fragile marsh, don’t disturb nesting or roosting birds, and leave no trace.

Nearby

  • Camp village – the nearest stop for a pint or a coffee, with three pubs, Ashes Coffee Bar and an annual Sheep Fair in September.
  • Killelton – a ruined famine-era village east of Camp, abandoned in the 19th century.
  • Caherconree – one of the highest promontory forts in Ireland, on the mountain above Camp.
  • Blennerville Windmill – a restored 19th-century windmill and heritage centre on the Tralee side.

Time your arrival to the falling tide, give yourself room to walk out and back before the water returns, and watch the brent geese settle onto the roost as it does.
