Ilnacullin, or Garinish Island, renowned as a unique island garden of rare beauty, is nestled into the sheltered coastal harbour of Glengarriff in Bantry Bay.  The gardens were set out in the arts and crafts style in Edwardian times and contain classical formal gardens and architecture set within natural, Robinsonian style, surroundings.

Visitors can discover a wealth of unique architectural & horticultural gems, including an Italianate garden with formal pond, pavilion, Casita and lawns; walled kitchen garden with herbaceous borders, fruit, roses & climbers; Martello tower with fine panoramic views; and the Happy Valley with its Grecian Temple, shrubberies and rare trees.

Bryce House (a short walk from the walled garden) is a fitting memorial to the visionary creators and custodians of this unique place.  Built c1912 in an Edwardian picturesque style, Bryce House became the residence of Violet, her son Roland, their housekeeper Margaret O’Sullivan and head gardener Murdo MacKenzie.
