Hven is a small island sitting in the Øresund strait, the brackish, tidal channel between Sweden and Denmark. Currents run through the strait regularly, and divers should plan entries and exits around them. The island's main draw is wreck diving: our database lists named wrecks including the Robert SS, Leda Af Rønne, Otto S/S, and several others, spanning a depth range from shallow reef sites down to around forty metres. Kelp forest and reef dives also feature, and the species list includes harbour seal, bobtail squid, catshark, and lumpfish. Both shore and boat entries are available, and sites suit beginners through to intermediate divers.

Water is cold year-round, sitting near freezing in winter and warming to around seventeen degrees Celsius at the peak of summer. A drysuit is practical for most of the year, with a thick wetsuit viable only in the warmest months. Visibility is variable and currents from the strait can strengthen quickly, so timing dives around slack water is advisable.
