Overview
Red Rock faces south-west across Dublin Bay, 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, and for a quiet dip off the rocks after a warm day, rather than for a sandy beach afternoon – this is a compact, pebbly cove at the south-west corner of the Howth peninsula, not a strand.
The site runs to about 21 hectares of protected coastal habitat, part of the UNESCO-designated Dublin Bay Biosphere, bounded by Carrickbrack Road and Sutton Castle above and Dublin Bay below. Most people reach it on foot from Sutton, at the western end of the Howth Cliff Walk.
Getting there and the walk
The cliff path is clearly waymarked and mostly flat, though the last drop to the water is over uneven steps and rock.
- By train: take the DART to Sutton Station and follow the blue waymarkers for the Howth Cliff Walk. Allow 20–30 minutes down to the cove.
- By car: there is parking on Sutton Road near the Martello tower, but spaces are limited and may be subject to local restrictions; street parking nearby is tightly enforced. On summer weekends, arrive before 10am or come by DART.
- The full loop: from Howth Village the whole circuit runs about two to two-and-a-half hours; the Black Linn Loop guide has the detail.
What to expect
The cove is a mix of pebbles, sand pockets and the red sandstone platforms that name it. A sheltered inlet holds a calm, shallow pool at the right state of the tide, and people perch on the rocks and swim off them, especially on a hot evening. The water is Irish Sea cold outside a heatwave, so bring a wetsuit or a thick towel. There is no lifeguard, so check the tide before you get in and keep an eye on it.
Above the cove stands the Sutton Martello tower, also known as Red Rock Tower – it is private, but the walkway around it gives a clean view over the bay. 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.
The story locals tell is of a man who slipped from the steep cliffs above and landed on the sloping red rocks below, then walked away unhurt. Unverifiable, but it fits the place – the rock ledges do angle rather than fall sheer. The cove has been a quiet swimming retreat for Dubliners since the early twentieth century.
Practical information
Red Rock is free to reach and open year-round, but it has no facilities – no toilets, no kiosk, no bins. 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.
One honest caveat: the appeal here is the setting and the sunset, not the swimming or the sand, and the final scramble down is awkward. At low tide the platforms are fully exposed and best for walking and photography; at high tide the inlet fills but the rocky descent turns slick. Check the tide tables and wear shoes with grip.
