Krka at Otočec castle
At Otočec castle the slow lowland Krka splits into two arms: the natural northern one and a southern arm probably dug for the castle's defence. The 2017 PAS sheet calls both full of life and deep enough – up to about 3 m – for an easy dive in shallow, summer-warm water. The gravel bed is mostly covered by dense water plants that in places make it impossible to move underwater, so you can easily spend over an hour exploring the northern arm. The castle and its landscaped grounds make a scenic backdrop.
depth: 0–3 m
