Inishfree (or Inis Fraoigh) is a small island 5km off the coast of Donegal. In the 4th and 5th century, this remote island was the domain of Niall of the Nine Hostages, future king of Ireland. Today, pristine nature and the tranquility of a simpler time await those visitors who wander off the beaten path. The island's few inhabitants organise activities for visitors involving local culture, music, art, crafts, poetry, angling, boating and more.

In the booklet 'Dagje Heusden' there are two self-guided city walks including a map of the fortress. The booklet gives you information about the history of the fortress and the historic buildings that you will pass along the way. The two routes can be walked independently. Duration: 1 - 1.5 hours. The 'Through The City' (Door de Stad) walk starts at the Visitor Centre, taking you past the historic Catharijnekerk, by national monuments and beautiful old buildings in the town, alongside windmills and over the towns ramparts. The second walk, 'Fortifications' (Vestingwerken) also starts at the Visitor Centre and goes along the bastions and fortifications, past the historic cannons, the windmills and the marinas. Every Sunday afternoon you have the option to go on a guided tour with a “City Guide”. The guide will tell you about the town’s history, the fortifications, about the restoration of the city and the striking buildings. The start is always at 2:30pm at the Visitor Centre at Pelsestraat 17 in Heusden, and takes around 75 minutes.
