An exciting adventure for the physically fit is to climb the city walls from Kotor up to the Castle of St. John. The 1200 foot assent entails over 1350 steps through a winding series of switchbacks that stretch for over two miles. Some of these bastions from the 15th century reach a height of 50 feet. The shorter ones provide great views of the city and bay below. Half way up you reach the Chapel of Our Lady of Health which was built in 1518. It is a great place to pray you will survive the rest of the trek up the St. John Mountain to reach the fortress and the Chapel of St. Ivan.
