About a one hour hike from Jelsa is what remains of the Greek Tower Tor, dating back to the fourth century BC. Situated 230m above sea level, the hike is worth it for the view alone, with the ancient watchtower offering spectacular views of not only Jelsa, but but also Vrboska and the Split and Makarska coastline. There are unfinished walls and man-made terraces around the tower, suggesting that it was also living quarters.
