Pro Tips

  1. 1.Book your boat transfer in advance during summer months as spaces fill quickly. Several operators run from Coliemore Harbour in Dalkey village.
  2. 2.Bring sturdy shoes or hiking boots as the island terrain is uneven with rocky paths and no facilities. Sandals are not recommended.
  3. 3.Pack a complete picnic including plenty of water as there are no shops, toilets, or amenities on the island itself.
  4. 4.Visit Coliemore Harbour 15 minutes early to ensure parking (limited spaces) and check weather conditions, as rough seas can cancel trips.
  5. 5.Bring binoculars for wildlife spotting. The island is home to wild goats, various seabirds, and you may spot seals in the waters around the island.

Best Time to Visit

Late spring through early autumn (May to September) offers the best weather and calmer seas for boat transfers. Weekday mornings are less crowded than weekends. Aim for low to mid-tide for better beach access and rock pooling opportunities.

What to Know

Boat transfers cost approximately 15 to 20 euros per person (check with operators for family rates). There are no facilities on the island, so bring everything you need including food, water, and sun protection. The island is not accessible for strollers or wheelchairs due to the boat transfer and rocky terrain.

Seasonal Notes

Boat transfers operate primarily from April through September, weather permitting. Winter visits are possible but depend heavily on sea conditions and require advance booking. Summer months (June to August) offer the longest daylight hours and warmest weather but can be busiest. Always check weather forecasts as trips are cancelled in rough seas.
