To the north of Makriyialos near the village of Pefki, there are two caves of interest. One is the cave of Apaloustres which is relatively easy to visit and the other is Latsida Vrikou where traces of Neolithic habitation have been discovered recently. There are however other well known cave formations in the area of Sitia such as: * the caves at Mikro Katofigi and Megalo Katofigi which are 425 and 450 metres above sea level. * the cave of Exo Latsidi, one of the deepest in Crete, near Sitano at a height of 610 metres.
