Overview

The first thing to know about Collanmore Island is that you cannot just turn up. At 700 acres it is one of the largest of the drumlin islands in Clew Bay, off the Mayo coast, and the entire island now works as a single private-hire operation: the Collanmore Island Lodge, which sleeps up to 22 and takes one group at a time. The 2022 census recorded five permanent residents, down from a peak of 215 in 1851 – a decline that reads like the wider story of Ireland’s islands in one line.

What you get for the booking is exclusive use: a white-sand beach, a full view of Croagh Patrick across the water, and a choice between guided water sports, island walks, or doing nothing at all in the lodge’s hot tub while the tide moves across the bay. Access is by a short rib-boat transfer, arranged as part of the package.

History & Sailing Heritage

Collanmore’s modern identity was shaped by Les Glénans, the non-profit sailing school that operated on the island for many years. The bay’s naturally sheltered coves and consistent wind patterns made it an ideal training ground for dinghy sailing, catamarans, and sailboarding. The school drew learners from across Europe, and the island’s infrastructure was built to house them and their instructors.

When the sailing school relocated, the island transitioned into a private retreat. The small permanent community that remains keeps the island’s everyday character intact, while the lodge repurposes the existing facilities for luxury accommodation and guided outdoor programmes. The sailing legacy still influences the current activity menu, with a strong emphasis on hands-on watercraft and coastal navigation.

Getting There & Island Access

The island is not connected by road and can only be reached by boat. All transfers are coordinated by The Adventure Islands team, which operates a high-speed rib-boat service from Rosmoney Pier.

  • By road: From Westport, follow the R335 to the turn-off for Rosmoney Pier (approximately 12 km). Free parking is available at the pier, which has a modern pontoon.
  • By boat: The rib transfer takes roughly twelve minutes and includes a safety briefing before departure.
  • Accessibility: Getting on and off a rib boat involves a step down onto a small craft, so discuss any mobility needs with the lodge in advance rather than assuming step-free access.

Because the boat service is tied to the lodge’s booking schedule, transfers must be arranged in advance through the official website. Independent day-trippers without a lodge reservation are not accommodated on the standard transfer rota.

Water Sports & Guided Adventures

The island’s programme is built around the natural conditions of Clew Bay. All equipment is supplied, and activities are led by experienced guides who tailor sessions to group ability.

  • Sea kayaking: Sturdy, stable kayaks are provided, with children taking part under adult supervision; check minimum ages with the lodge when booking a family group.
  • Stand-up paddle boarding (SUP): A 2.5-hour session covers basic balance, stroke technique, and navigation between sheltered points. Suitable for beginners.
  • Guided sea-safari powerboat rides: High-speed tours that showcase the island’s coastline, nearby islets, and tidal channels.
  • Guided walks: Trail routes cover the island’s interior and coastal edges. Guides share local folklore, geology, and the history of the sailing school era.
  • Bushcraft and raft building: Practical, hands-on sessions focused on natural materials and traditional building techniques. Popular with school groups and corporate teams.
  • Swimming & snorkelling: Designated safe zones in the sheltered bays offer clear water and good visibility.
  • Private charters: Water-skiing and private sailing sessions can be arranged through local providers for groups seeking additional equipment or specialised instruction.

A typical itinerary might start with a morning kayak or SUP session, followed by a guided walk and a midday break. Afternoon options include a powerboat safari or a raft-building workshop, depending on weather and group preference.

Lodge Facilities & Wellness

Collanmore Island Lodge is designed for private hire, meaning the entire property and its surrounding grounds are available to your group. The accommodation blends practical amenities with coastal wellness features.

  • Dining & entertainment: A fully equipped kitchen supports private catering, with personal chef options available. A private bar and outdoor fire-pit provide evening gathering spaces.
  • Wellness: A nine-person hot tub, sauna, steam room, and seaweed baths overlook the water. The facilities are designed for post-activity recovery and relaxation.
  • Sea Water Park: A dedicated water playground features trampolines, slides, and running tracks. It is suitable for children and adults alike.
  • Bespoke events: Hosts can arrange themed entertainment, including traditional Irish music sessions, murder-mystery evenings, or private dining experiences. The space is frequently booked for weddings, corporate retreats, and milestone celebrations.

Practical Information & Booking

Collanmore Island operates on a reservation-only model. Groups range from small family gatherings to larger corporate teams, with a maximum capacity of 22 guests. The lodge handles all activity scheduling, catering coordination, and boat transfers through a single booking portal.

Activity packages include wetsuits, kayaks, paddle boards and life jackets; confirm minimum ages for the water programmes when you book for children. Weather-dependent activities are rescheduled where possible, but pack waterproof layers and non-slip footwear regardless of the forecast.

Contact & Booking All reservations, activity packages, and bespoke entertainment requests are managed through the lodge website: collanmoreislandlodge.com. For direct enquiries, email info@theadventureislands.com or call +353 862 518 252.

Exploring the Wider Mayo Coast

Clew Bay is famously said to hold 365 islands, though only around 140 are actually named; Collanmore is one of the biggest. Closer to the mainland, Achill Island has the dramatic cliffs and long strands, while inland Ballycroy National Park covers one of Ireland’s largest tracts of wilderness. All of these, though, are trips off the mainland – Collanmore itself is a destination you commit to, not a stop you pass through.

Book well ahead for summer weekends and school holidays, as the exclusive-use model means one group has the island at a time. Check the tide tables before your transfer too: low water affects the depth at Rosmoney Pier and the approach to the island.
