Bustling town in Northern Ireland with ancient castle, cosy pubs and an island

Enniskillen, the largest town in County Fermanagh in Northern Ireland, sits between Upper and Lower Lough Erne waterways and works as a base for exploring the Lakelands. The town balances history and easy-going local life, from a 15th-century castle and Georgian mansions to a monastic site dating back to the 6th century. Enniskillen Castle, built by the Maguire clan over 600 years ago, is now home to the Fermanagh County Museum and the Inniskillings Museum under one ticket priced at £6.50 for adults and £4.50 for children. Visitors can also reach Devenish Island by boat for its 6th-century monastery founded by St Molaise, with surviving remains from the 12th, 13th and 15th centuries.
