Ransvik is an easily accessible dive site by either land or sea, although you'll need to go down some wide stairs if going there by land (and back up after the dive!). It offers depths of around 3-5 m closer to shore where you'll have plenty of boulders to swim around, and a mere 50 meters from shore a more flat bottom at about 15 m that gently slopes downward to greater depths. There's a dive shop east of the town Mölle, by a camping site, for renting gear or filling up on air/nitrox.
