Senja is the kind of place where one forgets to lock the door. The major threat to the visitor is the visitor himself. Raging storms, rocky terrain and low population density call for caution when venturing into the elements. That said, there are plenty of beauty spots that can be reached even by inexperienced nature lovers. It's all about informing oneself before heading out.
A number of low key deep sea fishing resorts is found along the west coast. If you're out fishing, make sure to take weather forecasts and safety instructions seriously.

Senja has its own particular accent of Northern Norwegian, that is particularly pronounced on the west coast. Texas-style rounded r's and high intensity are characteristic traits. Until recently, Sami dialects reminiscent of the one in Northern Sweden were spoken in inland hamlets, but Sami is today a dying language on the island.
