Connemara National Park & Diamond Hill Hike - A must-visit attraction in Galway

🕐 Last updated: March 25, 2025

Step into the wild heart of County Galway at Connemara National Park, a place of raw beauty where mountains meet bogs and windswept heaths. The park's centrepiece is Diamond Hill, sparkling with quartzite rock and rising 442 meters. Hiking here throws open the door to Connemara's famously dramatic landscapes, all watched over by the Twelve Bens mountain range. The park itself, opened in 1980, looks after land with a past, once part of the Kylemore Abbey estate and the Letterfrack Industrial School. You can still see traces of old turf cutting and grazing pastures, and you might even spot the hardy Connemara ponies, living symbols of the region.

Ready for a walk? You've got two main choices. The Lower Loop is a gentle 3-km wander through bogland and woods, past grazing cattle, with glimpses of Barnaderg Bay. It's great for families and takes about 1.5 hours, leading you to where the tougher trail begins. If you're up for a challenge, the Upper Trail stretches for 6-7 km, climbing steep quartzite paths and rocky slopes. The final ridge requires a bit of care, but the reward is breathtaking: a full 360-degree view taking in the Twelve Bens, Kylemore Abbey shimmering below, Pollacappul Lough, and even distant islands like Inishturk and Inishbofin out in the Atlantic. Keep an eye out for the "lighthouse stone," a big chunk of quartzite perfect for catching your breath mid-climb.

Exploring here means walking through a landscape shaped by both nature and people. Gravel paths and boardwalks guide you past wildflowers like marsh orchids and purple heather, depending on the season. The views from the top change constantly with the weather – misty mornings, golden sunsets, or maybe even scenes that feel straight out of Tolkien's Middle-earth (he was inspired by Connemara!). Summer brings bright colours and more people, while autumn and winter offer quiet solitude and stark beauty. For safety, there's a one-way system on the west face, but always watch your step on the exposed parts. Need info or a break? The visitor centre, set in old farm buildings, has maps, a café, and displays about the area's nature and history.

What makes Diamond Hill special? It's that mix of a tough climb followed by peaceful, wide-open views. It's a landscape that feels different hour by hour. Seeing the summit reflected in the lake near the visitor centre is a lovely touch. Out here, it's just the wind, the wildflowers, and the distant sea. Whether you tackle the full hike or stick to the lower paths, you'll get a real feel for Connemara's untamed spirit.

By Car
The most straightforward way to access the park is by car. From Galway City, the drive takes approximately 1.5 hours via the N59 towards Clifden. Follow the N59 north, then take the R344 or L1101 into Letterfrack, where the visitor center is located. From Dublin, the journey is around 4 hours, while Westport is 1 hour away. The Connemara Loop Drive offers a scenic alternative route. Note that GPS navigation may occasionally provide incorrect directions, so consult local maps or signs for guidance.

By Bus
Public buses connect the park to major towns. Citylink Bus 923 runs from Galway City to Letterfrack via Clifden (journey time: ~1h50m). Bus Éireann 423 travels from Westport to Letterfrack (~1h10m). Buses are infrequent, so check schedules in advance via Citylink or Bus Éireann. The visitor center is a short drive or walk from the Letterfrack stop.

Local Transport & Tours
For those without a car, taxis can be hired from Clifden (20-minute drive away). Organized tours departing from Galway offer convenience, combining transportation with guided hikes and time at the visitor center. These tours often include stops at nearby attractions like Kylemore Abbey, just 3 miles from the park.

The park is situated in Letterfrack, a village near Clifden in County Galway. Nearby towns like Clifden and Westport serve as hubs for accommodation and onward travel. Always confirm park opening hours and trail conditions before visiting, especially during winter months when weather can disrupt access.

Parking

The primary parking facility is located at the Visitor Centre in Letterfrack, adjacent to the start of both the Lower and Upper Diamond Hill trails. This large car park is free of charge and typically sufficient for most visitors, though it fills quickly during June to September and on weekends. To secure a spot, arrive early, as congestion is common later in the day. The parking area is approximately 400 meters from the Visitor Centre entrance, with a short walk leading to the trailhead and information kiosk.

For visitors arriving during peak times, overflow parking is available along the access road leading to the Visitor Centre. This stretch provides additional spaces when the main lot is full. Note that overnight parking or camping is prohibited in the park's car park; camper vans should use designated local sites instead.

The park's parking is designed for daytime visitors only, and there are no fees or payment methods required for parking or entry. While the main car park accommodates most vehicles, specific accessibility facilities for disabled parking are not detailed in available sources-visitors requiring such amenities are advised to contact the park in advance.

Alternative routes to the park include approaching from Clifden (via the N59 Westport Road, with the entrance on the right before Letterfrack) or from Leenane (on the N59 Leenane Road, with the entrance 200 meters past the village). Always allow extra time during summer months to account for potential delays and parking availability.
