From gentle coastal paths to Ireland's highest peak, here's how to plan a hike that fits your trip—and where to base yourself for the best access.
Easy Walks in and Around Dublin
If you're flying into Dublin and want a walk without leaving the city, head to the Howth Cliff Path. The loop starts at Howth DART station (30 minutes from Connolly) and takes 2–3 hours along the cliffs to the Baily Lighthouse and back. It's waymarked and mostly flat, with a few steep sections. Go on a weekday morning to avoid crowds, and bring a windproof layer—the exposed sections can be breezy even in summer. The view across Dublin Bay to the Wicklow Mountains is your reward.
For something wilder, catch the DART south to Bray and walk the Bray to Greystones Cliff Walk. This 7km linear route is flat and takes about 2 hours, with the option to return by DART from Greystones station. The path is well-maintained but can be muddy after rain, so wear sturdy shoes. Both walks are free and require no booking. They're ideal if you're staying in Dublin and want a half-day outdoors. Book a hotel near Connolly or Tara Street stations for easy early starts.
Mountain Days: Wicklow and Kerry
Wicklow Mountains National Park, 45 minutes' drive from Dublin, offers the 6km Spinc and Glendalough White Route. This waymarked trail climbs 300m to a ridge with views over the Upper Lake, taking 3–4 hours. It's steep in places but doesn't require scrambling. Start early to secure parking at the Glendalough visitor centre (€4). Alternatively, the easier Green Road walks around the lake are flat and take an hour. For accommodation, consider staying in Laragh or Roundwood; a hotel there puts you 15 minutes from the trailhead.
In Kerry, the 10km Gap of Dunloe walk from Kate Kearney's Cottage to the Head of the Gap is a classic. It's on a paved road shared with jaunting cars, so keep left and stay alert. The walk takes 2–3 hours and gains 200m. To avoid the crowds, go before 10am or after 4pm. Base yourself in Killarney, where hotels range from budget to luxury, and you're a 15-minute drive from the cottage. If you want a bigger challenge, Carrauntoohil (1,038m) via the Devil's Ladder is a 6-hour round trip—only for experienced hikers with proper gear.
Planning Your Hiking Base
Your choice of base matters more than you might think. For easy access to Wicklow, Dublin hotels near Connolly Station let you combine city comforts with day trips—trains to Bray and buses to Glendalough run frequently. For Kerry, Killarney is the obvious hub: it has the widest range of accommodation, from hostels to four-star hotels, and you can walk to the national park from town. Avoid staying in remote cottages unless you have a car; public transport to trailheads is limited. Book hotels in Killarney or Dublin at least two weeks in advance for summer weekends.
Consider the season, too. May, June and September offer the best balance of daylight and weather, with fewer crowds than July and August. Winter hikes are possible but days are short and conditions can change quickly. Always check the Mountain Safety website before setting out. For a stress-free trip, I'd book a hotel in Killarney for Kerry hikes and a Dublin city centre hotel for Wicklow and coastal walks. That way you can leave your luggage behind and travel light.
Frequently asked questions
Do I need hiking boots for these trails?
For the Howth and Bray walks, sturdy trainers are fine. For mountain routes like Spinc or Carrauntoohil, waterproof hiking boots with ankle support are essential. Weather can turn quickly, so pack a rain jacket regardless.
Is public transport available to the trailheads?
Yes, for many. Howth and Bray are on the DART. Glendalough is served by bus from Dublin, but services are limited. Killarney's Gap of Dunloe is a short taxi ride from town. A car gives more flexibility for remote areas.
What should I pack for a day hike in Ireland?
Bring waterproofs, layers, water, snacks, a map (or downloaded offline maps), a charged phone, and a small first-aid kit. Even on sunny days, conditions can change. Let someone know your route and expected return time.
