The beautiful, old mule track between Gonea and Kotronas is difficult to walk at the moment because it is overgrown in places. Long trousers as protection against the thorns are definitely helpful.
The "old mule trail" is a monument, but due to the partially thorny overgrowth, it will be impassable for regular hikers in spring 2025. Long pants aren't enough; you should at least bring a pair of pruning shears; those following behind will thank you.
