Howth Cliff Walk: 5 Routes for Every Fitness Level

If someone tells you to "do the cliff walk in Howth," the first thing you need to know is: there isn't just one. There are five colour-coded trails looping around the headland, and picking the right one makes the difference between a gentle stroll with sea views and a three-hour hill march through bog and heather.

All five trails are waymarked with coloured arrows and start from the village. Here's what you're actually signing up for with each one.

The Green Route (Cliff Path Loop)

Distance: 6 km · Time: 1.5–2 hours · Elevation: 130m · Difficulty: Easy to moderate

This is the one everyone means when they say "the cliff walk." It follows the coast from the harbour out past the Nose of Howth, with Ireland's Eye sitting in the water directly ahead and the Bailey Lighthouse perched on the rocks below. The path is well-trodden and mostly flat once you're up, though the initial climb out of the village will warm you up fast.

It's the most popular route for a reason. You get the dramatic cliff-edge views without needing hill-walking gear. That said, it's still an exposed coastal path. Wear proper shoes (not sandals, not Converse) and bring a jacket even if it looks sunny when you set off. This is Dublin's northside coast, not the Riviera.

Best for: First-time visitors, families with older kids, anyone who wants the classic Howth photos without a full expedition.

The Blue Route (Tramline Loop)

Distance: 7 km · Time: ~2 hours · Elevation: 130m · Difficulty: Moderate

The Blue Route follows the old tramline that once connected Howth to the Hill of Howth. The tracks are long gone, but the route remains as a wide, gently graded path through woodland and open hillside. It's a step up from the Green in distance but not dramatically harder.

You'll get views of Ireland's Eye and the harbour, plus some sections through shaded woods that feel a world away from the exposed cliffs. It's quieter than the Green Route, which is half the appeal. On a summer Sunday, the Green path can feel like Grafton Street.

Best for: Anyone who wants a bit more than the Green Route without committing to a full morning. Good in mixed weather since the woodland sections offer shelter.

The Red Route (Black Linn Loop)

Distance: 8 km · Time: ~2.5 hours · Elevation: 160m · Difficulty: Moderate

The Red Route takes you through Black Linn, a rocky area on the eastern side of the headland where the landscape gets wilder and less manicured. You'll climb higher than the Green or Blue, and the terrain underfoot gets rougher. Proper walking shoes are non-negotiable here.

This is where you start to feel like you're actually in the countryside rather than on a suburban nature trail. The views open up to include Lambay Island to the north and the full sweep of Dublin Bay to the south. On a clear day, you can see the Wicklow Mountains across the water.

Best for: Regular walkers who want something with a bit more bite. The 2.5-hour timeframe makes it a solid morning walk with time for lunch after.

The Purple Route (Bog of Frogs Loop)

Distance: 12 km · Time: 3+ hours · Elevation: 240m · Difficulty: Moderate to challenging

This is the big one. The Bog of Frogs loop covers the full headland: Howth Hill, Red Rock Beach, the Bailey Lighthouse, and everything in between. It's 12 kilometres of coastal path, heathland, bog, and woodland. If the Green Route is a sampler, this is the full menu.

The climb from the DART station is steep and long. There's no way to sugar-coat that. Your thighs will know about it. But here's the local trick: take the H3 bus to Howth Summit and walk mostly downhill. The bus runs every 7–8 minutes from Abbey Street and drops you right at the top. Walk down, finish at the DART station, and take the train back to town. Bus up, DART back. That's how Dubliners do it.

The views from the summit are extraordinary. On a clear day you can see Dublin city, the Wicklow Mountains, Lambay Island, and Ireland's Eye all at once. The bog section is named for the chorus of frogs you'll hear in spring, and it's genuinely one of the most unexpected sounds you'll encounter on a coastal walk.

Best for: Fit walkers who want the full Howth experience. Allow a full morning and bring water and snacks.

The Howth Head Walk (Linear)

Not colour-coded but worth knowing about: you can walk a one-way route from Howth Harbour to the Summit (or vice versa) in about 45–60 minutes. It's not a loop, so you'll need to get the bus back or retrace your steps, but it's useful if you're short on time or just want to get to the top for the views.

What to Bring

Regardless of which route you pick: walking shoes (not runners), a waterproof layer, water, and sun protection in summer. The headland is exposed and wind and rain can appear from nowhere, even in July. There are no shops or cafes once you leave the village, so bring anything you might need.

When to Walk

May, September, and October are the sweet spot. Mild weather, good visibility, and fewer people. Summer weekends are beautiful but busy, especially the Green Route. Winter walks are atmospheric but the paths can be muddy and the exposed sections genuinely cold. Always check the forecast before the Purple Route.
