Things to Do Across County Dublin: Go Beyond the Tourist Traps
Beyond the city centre, County Dublin runs from coast to mountains. Walk the Howth cliff path over Dublin Bay, roam Phoenix Park, Europe's largest enclosed urban park at twice the size of Central Park and home to wild deer, visit Malahide Castle, lived in by one family for nearly 800 years, and the coastal villages of Dalkey and Killiney.
Established during the Norman invasion in the 12th century, Dublin is one of the oldest counties in Ireland and was originally part of the ancient kingdom of Leinster.
Sure County Dublin is home to the capital but don’t confine yourself to the city centre! When exploring County Dublin, you'll quickly discover it's a place of stark contrasts. Within minutes, you can journey from bustling city streets to tranquil coastal villages and rugged mountains. This diversity sets Dublin apart from its neighboring counties.
County Dublin Attractions
Dublin Castle
This 13th-century fortress stands where Viking settlers first established a settlement. Unlike Kilkenny Castle's medieval grandeur, Dublin Castle blends architectural styles from Norman, Georgian, and Victorian periods, reflecting the city's evolving history.
Visitor Info: Allow 1.5-2 hours for the guided tour, which provides access to the State Apartments and medieval undercroft. Mornings typically see fewer crowds, especially on weekdays. The Chester Beatty Library within the castle grounds deserves an additional hour.
Howth Head Peninsula
A great spot for a run or hike, this stunning headland offers some of the most spectacular coastal walks in Leinster. The Howth Cliff Path provides panoramic views across Dublin Bay that rival even Wicklow's famous cliff walks. You'll spot Ireland's Eye and Lambay Island offshore, and on clear days, the mountains of Wales.
Visitor Info: The full loop walk takes 2-3 hours, but shorter options are available. Morning visits offer the best lighting for photography, while sunset views are particularly magical. The village of Howth itself deserves another hour for exploring.
Phoenix Park
Twice the size of New York's Central Park, Phoenix Park is Europe's largest enclosed urban park. Unlike the manicured formal gardens of Powerscourt in Wicklow, Phoenix Park maintains a wilder, more natural character with herds of wild deer roaming freely since the 17th century.
Visitor Info: You could spend an entire day here. The park houses Dublin Zoo, Áras an Uachtaráin (the President's residence), and the Victorian People's Flower Gardens. Renting bikes is the best way to cover the vast grounds. Weekday mornings offer the most peaceful experience.
Malahide Castle and Gardens
This medieval castle has been inhabited by the same family for nearly 800 years, making it one of Ireland's oldest continuously occupied castles. The Talbot family's connection to Malahide far outlasted the Butler family's tenure at Kilkenny Castle.
Visitor Info: Plan for 2-3 hours to tour the castle and explore the botanical gardens. The gardens are awe-inspiring in late spring, but the castle's interior is fascinating year-round. Weekday visits are considerably less crowded.
Dalkey and Killiney
These adjacent coastal villages offer a glimpse into Dublin's wealthy maritime past and present. The area combines historical sites with stunning sea views and has been home to numerous Irish literary figures and celebrities. Killiney Hill provides views that locals often compare to the Bay of Naples.
Visitor Info: Dalkey Castle requires about an hour, while a walk up Killiney Hill takes another hour. The DART train service makes this area easily accessible.
The National Botanic Gardens
These Victorian gardens house over 15,000 plant species and historic glasshouses that rival those at Kew Gardens in London. The palm house features a groundbreaking architectural design.
Visitor Info: Allow 2-3 hours for a complete visit. Spring and early summer showcase the most blooms, but the glasshouses are impressive year-round. The gardens are closed on Mondays during winter months.
Hidden Dublin Gems
Poolbeg Lighthouse Walk
The Great South Wall extends 4km into Dublin Bay, ending at the distinctive red Poolbeg Lighthouse. Most tourists never venture here, but it offers unparalleled views of Dublin Bay and the busy shipping lane into Dublin Port. Local lore tells of smugglers using the wall during the 18th century to bring contraband into the city, evading customs officials.
Dubliners call this walk "the greatest sea view in Dublin," and on windy days, you'll see locals gathering to watch the spectacular spray as waves crash against the wall. Bring a flask of tea and join them for a two-hour walk.
The Forty Foot Swimming Spot
Locals have used this historic sea-swimming location in Sandycove for over 250 years. Immortalized in James Joyce's "Ulysses," it was traditionally a men-only bathing spot until women protestors forced integration in the 1970s. The water remains around 9°C year-round, and you'll always find hardy locals taking their daily dip - including several who swim every day of the year, even on Christmas morning.
When swimming here, locals will tell you to look for "the pot" - a naturally formed circular area with slightly calmer waters that makes entry easier for beginners.
Marino Casino
This neo-classical building is one of Europe's finest 18th-century architectural gems, yet many Dubliners have never visited. Despite its name, it was never used for gambling - "casino" here means "small house." The building is an architectural masterpiece of deception: what appears to be a single-room structure actually contains 16 rooms across three floors.
Local architects still study the Casino's perfect proportions and clever design. During restoration work in the 1970s, workers discovered hidden messages from the original craftsmen written on interior walls over 200 years earlier.
The Hell Fire Club
Sitting atop Montpelier Hill in the Dublin Mountains, this ruined hunting lodge from the 1720s was reportedly the meeting place for an infamous gentlemen's club known for debauchery and occult activities. Originally built with stones from a prehistoric passage tomb, locals blamed the desecration for supernatural occurrences.
Dublin parents have frightened misbehaving children with tales of the Hell Fire Club for generations. Folklore includes stories of a large black cat appearing during storms and card games with mysterious strangers who revealed cloven hooves beneath their boots.

Local Business Highlights
The Old Spot
This gastropub in Bath Avenue preserves the cozy atmosphere of an Irish pub while serving exceptional food. Their slow-cooked beef cheek with bone marrow mash has developed a cult following among Dublin foodies. Sunday roasts often sell out by early afternoon.

The Library Bar
Hidden on the first floor of the Central Hotel, this converted Victorian library retains its original bookshelves and leather armchairs. Their Irish coffee uses a 100-year-old recipe with locally distilled whiskey.
Unlike Temple Bar's tourist-focused pubs, The Library Bar remains a favorite meeting spot for Dublin's literary community. Local writers often draft their works here, continuing a decades-old tradition.
Avoca Handweavers
