Overview
Berehaven is Ireland’s largest whitefish port, landing and exporting over 20,000 tonnes of fish a year to markets in Europe and Japan. It sits at the heart of the Beara Peninsula, a deep-water anchorage doubly sheltered behind Bere Island, and reckoned one of the safest natural harbours in the world. This is a working port first and a visitor stop second: trawlers share the calm water with yachts and the small ferries that cross to the island.
If you have a day, give it to Bere Island and Lonehort Battery. The harbour itself is the view; the island is where you actually go.
A legacy of fortification and trade
The harbour’s strategic shelter drew settlers and soldiers alike. The O’Sullivan Bere clan held nearby Dunboy Castle to control these waters and their rich fisheries, and the 1602 Siege of Dunboy was a turning point in the region’s history. In 1796 a French invasion fleet sheltered here during the failed landing at Bantry Bay, with Wolfe Tone aboard one of the anchored ships.
That vulnerability prompted heavy British investment in coastal defence. Four Martello towers were built on Bere Island in 1805 to guard the approaches. The harbour’s importance carried into the world wars: the US Navy established a naval air station here on 29 April 1918, and the deep anchorage served both the Royal Navy and US Navy as a base for protecting convoys bound for America.
After the 1921 Anglo-Irish Treaty, Berehaven was one of three Treaty Ports retained by the United Kingdom, a Royal Navy anchorage until they were handed over to Ireland in 1938.
Exploring Lonehort Battery
The most impressive survivor of that defensive network is Lonehort Battery on Bere Island, completed around 1899 and the largest of seven gun batteries built to protect the harbour. It still has its two six-inch guns, a dry moat, underground ammunition stores and a restored guardhouse. Guided tours run during Heritage Week and on select summer weekends, walking through the original tunnels and explaining how the battery worked as part of a coordinated coastal defence.
Crossing to Bere Island
The harbour is the gateway to Bere Island, with two independent operators running year-round. Both work first come, first served – no advance booking – and take cars, bikes and foot passengers.
- Bere Island Ferries leaves from the pier in the middle of Castletownbere, near the RNLI station, and reaches the western end of the island in about 15 minutes. Contact: +353 27 75009.
- Murphy’s Ferry leaves from The Pontoon, about 4 km from town on the Glengarriff road, and lands at Rerrin on the eastern end in roughly 20 to 30 minutes. Contact: +353 86 2423140.
Frequency increases in peak summer, and services can adjust for weather and tides, so check the seasonal timetable before relying on a particular crossing.
Coastal activities and local life
The sheltered water suits sea and shore angling – bass, pollack and mackerel – and the calm inner harbour is good for kayaking, canoeing and dinghy sailing. Around Bere Island you may see whales, basking sharks and dolphins offshore, and the cliffs and headlands are good for seabirds.
The Beara Way, a roughly 220 km long-distance walking trail, threads through the area with views over the harbour and the Caha Mountains; the Ring of Beara is the 140 km driving loop for those who would rather see it from the car. Bere Island has three of its own looped walks and a weekly parkrun (Saturday, 9.30am).
Castletownbere’s waterfront comes alive at the monthly market on the first Thursday of each month – weekly through summer – from 9am to 2.30pm, with fresh seafood, crafts and local produce. For a pint and a plate afterwards, McCarthy’s Bar on the square is the town’s best-known fixture.

Where to stay
Berehaven Lodge (berehavenlodge.com) is a 4-star self-catering property about 5 km from Castletownbere, overlooking the harbour and Bere Island, with a private beach and marina access. Its Berehaven Pods offer glamping with sea views for a lighter option.
Nearby attractions
- Dunboy Castle: Ruins of the O’Sullivan Bere stronghold, 2 km west of the harbour.
- Derreenataggart Stone Circle: A prehistoric circle about 1.5 km north-west of town.
- Martello Towers: Four early-19th-century coastal defence towers on Bere Island, visible from the water.

Plan around the monthly market or a Heritage Week battery tour to catch the harbour at its busiest. Otherwise the ferries run all year, and crossing to Bere Island for a walk and a coffee looking back at the mainland is the simplest good day out here.
