2 Best Sights in Connemara and County Mayo, Ireland

The 5,000-acre Connemara National Park lies southeast of the village of Letterfrack. Its visitor center covers the area's history and ecology, particularly the origins and growth of peat—and presents the depressing statistic that more than 80% of Ireland's peat, 5,000 years in the making, has been destroyed in the last 90 years. You can also get details on the many excellent walks and beaches in the area. The misleadingly named "park" is, in fact, just rocky or wooded wilderness territory, albeit with some helpful trails marked out to aid your exploration. It includes part of the famous Twelve Bens mountain range, which is best suited for experienced hill walkers. An easier hike is the Lower Diamond Hill Walk, at about 3 km (less than 2 miles). Ask for advice on a hike suited to your abilities and interests at the Park and Visitor Centre, which is on the N59 as you arrive in Letterfrack from Clifden, on your right, clearly signposted, not too far southeast of the center of Letterfrack.

Located in the southern territory of the Mullet Peninsula and covering 110 square km (42½ square miles) of Atlantic bogland and mountainous wilderness, Ballycroy is one of only six national parks in Ireland and utopia for the outdoor adventurer. Marked looped trails offer staggering views across Blacksod Bay and the Achill Islands. Once the sun sets, the area becomes a "dark-sky park," where visitors arrive with flashlights to witness the uninterrupted view of the heavens. The park is equipped with a visitor center and café. To camp, contact the park manager.
