Take part in a guided sightseeing cruise around the Mount Athos bay in Halkidiki to view the imposing western part of the Holy Mountain Athos in a Glassbottom vessel. This cruise departs every Tuesday, Thursday, and Sunday. However, on Tuesday the tour stops at the center of the village of Ammouliani, while on Thursday and Sundays it stops at Alykes beach.

After visiting the monasteries, take some fantastic photos as your boat passes the gorgeous Drenia islets or Donkey Islands as the locals refer to them. Explore the majestic island of Ammouliani by stopping there for 1.5 hours where you'll have the opportunity for swimming or to have lunch. On Thursdays and Sundays in May and September, if the weather is not good, the 1.5-hour stop will be at Ammouliani's Village. 

Finally, admire the yellow corals of the most famous reef in the region from the Glassbottom boat on the way back to Ouranoupolis, arriving back at the port at 4:30 PM.
