Initiate your summer with a fresh dip in the sea. Dive head-first off the fjord’s jetties, sun-drenched rocks, and floating swim platforms - or simply dip your toes into water as it hits the shore. Otherwise, hit the trails in Bymarka where you can submerge yourself in freshwater lakes and the tranquility of nature. And if the water is too fresh, head inside where Trondheim becomes tropical in the Pirbadet pools.
