Little Skellig

Overview

Little Skellig (Irish: Sceilig Bheag) is the smaller, more rugged companion to the UNESCO-listed Skellig Michael. Situated approximately 11 km off the Iveragh Peninsula in County Kerry, the island rises abruptly from the Atlantic as a dark, basaltic crag. Unlike its neighbour, which supported a monastic settlement for centuries, Little Skellig has never been inhabited. Today it operates as a strictly protected nature reserve, best experienced from the deck of a licensed tour boat. Its primary draw is the massive northern gannet colony, which makes the island the most important seabird site in Ireland.

History & Geology

The rock that forms Little Skellig dates back to the Late Devonian period, roughly 374–360 million years ago. It was created during the same mountain-building event that formed the MacGillycuddy’s Reeks, giving the island a direct geological link to Ireland’s highest peaks. Over millions of years, rising sea levels and coastal erosion isolated the outcrop, leaving behind a steep, weathered crag that reaches 134 metres above the waterline.

The island’s inhospitable terrain and lack of fresh water meant it never supported permanent human settlement. Instead, it remained a sanctuary for coastal wildlife until modern conservation efforts formalised its protection. In 2000, BirdWatch Ireland designated the twin Skellig islands as a 364-hectare Important Bird Area, and Little Skellig was formally declared a nature reserve. Landing on the island is strictly prohibited to prevent disturbance to the nesting colonies.

Wildlife Highlights

The island’s sheer cliffs and isolated location create ideal breeding conditions for a wide range of seabirds and marine mammals:

• Northern Gannets – Home to around 35,000 breeding pairs, this is Ireland’s largest gannet colony. Visitors can watch the birds perform coordinated take-offs and high-speed plunge dives into the Atlantic to catch fish.
• Puffins – Present from late April through early August, these birds nest in burrows along the lower ledges. Early summer offers the best chance to spot their distinctive beaks and hear their calls.
• Guillemots, Razorbills & Kittiwakes – These cliff-nesting species occupy the higher rock faces, adding movement and sound to the island’s vertical landscape.
• Grey Seals – Frequently seen hauling out on the submerged rocks at the island’s base, especially during calving season.
• Dolphins & Basking Sharks – The surrounding waters occasionally host pods of common dolphins and, in warmer summer months, filter-feeding basking sharks.

How to View Little Skellig

Because landing is forbidden, boat tours are the only way to experience the island up close. Licensed operators depart daily from Portmagee harbour, with additional services running from Valentia and Ballinskelligs. The journey takes roughly 15 to 30 minutes, depending on swell and wind. Vessels circle the crag at a regulated distance, allowing passengers to observe the gannet colonies, cliff-nesting birds, and resting seals without disrupting the ecosystem.

The open Atlantic waters around Little Skellig are part of the Wild Atlantic Way, and the sea can turn quickly. Boat crews are experienced in navigating these conditions and will adjust routes to ensure passenger comfort and wildlife protection. Clear days with a light breeze offer the best visibility and the smoothest ride.

Practical Information

Visiting Tips

• Book ahead – Daily departures are limited during peak summer months. Secure your ticket online at least a week in advance.
• Timing matters – Early morning departures catch the softest light for photography and typically offer calmer seas. Gannet chicks are most visible in flight from late July through August.
• Pack for exposure – The deck is fully exposed to wind and spray. Bring a windproof layer, sturdy non-slip shoes, sunscreen, and a hat. Binoculars are highly recommended for spotting puffins and cliff-nesting birds.
• Manage seasickness – The Atlantic swell can be unpredictable. Take motion sickness medication beforehand if you are prone to nausea, and sit near the centre of the boat where movement is minimal.
• Respect the reserve – Keep voices low, avoid sudden movements, and follow the crew’s instructions. Donations to BirdWatch Ireland help fund ongoing monitoring and conservation work.
• Combine your visit – Portmagee sits directly on the Ring of Kerry, making it easy to pair the boat trip with coastal walks, café stops, or an evening in the village. Many operators also offer combined tickets that include a visit to Skellig Michael on the same day.

For the clearest views of gannet chicks learning to dive, plan your trip for late July or early August, when the juvenile birds take to the air in their distinctive dark-and-white striped plumage.
