Garnish Island (Ilnacullin) – Ireland’s Tropical Secret
Location: Glengarriff Harbour, West Cork
Garnish Island, or Ilnacullin, is unlike anywhere else in Ireland. Nestled in Bantry Bay, it owes its subtropical climate to being sheltered by the Caha Mountains and ringed by protective pine forests. This microclimate allows exotic plants — from Italian gardens to Mediterranean shrubs — to thrive. Did you expect to find a tropical island in Ireland?!
How to Get There:
Regular ferry boats leave from Glengarriff Pier (about 15 minutes). On the way, keep an eye out for the resident colony of friendly seals sunning themselves on the rocks.
What to Expect:
Garnish is best known for its immaculate gardens, designed in the early 20th century by Harold Peto and Annan Bryce. You’ll find Italianate terraces, Grecian temples, and even a Martello tower with sweeping views over the bay. It feels more Riviera than Ireland.
Folklore & Stories:
Locals once called it a “garden for the fairies,” believing its sheltered, lush setting was enchanted. Some say the seals around the island are selkies — mythical seal-people who shed their skins to become human.

We haven’t even mentioned the rugged beauty! So, if you’re road-tripping in Cork and Kerry, Valentia Island in Kerry is worth visiting.
