Lake Matka is one of the most popular places for the citizens of Skopje to relax or do activities. But not like a vast lake that you may imagine. Actually, it is narrow and highlights the high cliffs of the mountains. The boat ride over to visit the small cave costs 5 euros per person and the guide speaks English, the hours are from 10 to 14 hours and it leaves from Planinski Sun Matka and the church of San Andrés. The tour lasts two hours and is really worthwhile. We entered via the Treska River and the canyon formed by its waters. It is impressive, not as much as in Mexico but enough to remind you.
