Overview
Red Rock is on the Sutton side of Howth Head, above Dublin Bay, and it faces south-west, which is the thing to know before you plan a visit: it is a sunset spot. As the light drops, the rust-red sandstone takes on a deep copper glow, and on a clear evening the Poolbeg chimneys sit black against the sky across the water. Come for that view from the marked coastal route, rather than for a beach afternoon.
The site is protected coastal habitat on the edge of Sutton, part of the Dublin Bay Biosphere.
Getting there and the walk
Use Fingal County Council’s Howth walking map to choose a marked trail. The Bog of Frogs loop follows purple arrows from Howth DART station and passes Red Rock. The Black Linn Loop guide covers another way round the head.
Keep back from the cliff edge and stay on the marked path. Check current access notices and conditions before you set out.
What to expect
The reddish sandstone is visible from the marked coastal route, and it is the rock that gives the place its name. Stay on the path and out of the water, and keep away from the rocks below the path. There is no shore access promoted here.
The Sutton Martello tower, also known as Red Rock Tower, stands above. Leave the tower and its private approaches clear. For birds, expect gulls, cormorants and razorbills along the cliffs through the year.
History and local lore
Red Rock has no monuments beyond the Martello tower and a few old stone piers; its character is in the rock itself, sandstone shaped over millions of years into smooth, rust-coloured platforms.
Practical information
There are no facilities on the path, so bring what you need and take your rubbish home. Sutton and Howth villages, both a short walk or drive away, have pubs, cafés and takeaways. Check current conditions and any signs on the route before you go.
