Agios Nikolaos enjoys a prime location within close proximity to the Lassithi's numerous traditional villages and historical sites. Lassithi's unspoiled beauty, from rugged mountains, to expansive plateaus and deep cliffs, make it one of the most exciting region’s of Crete, as do its important historical sites, with their traces of ancient civilizations. Nearby Spinalonga Island is an important part of Crete's history, thanks to its 15th century Venetian fortress, which later saw use as an infamous leper colony. The seabed of the nearby Mirabello Bay is the site of the ancient sunken city of Olous, the remains of which can be admired from a boat.
