Naustahvilft, also known as the Troll Seat, is a unique geological feature in the Kirkjubolsfjall mountain overlooking Isafjordur in Iceland. Legend has it that a troll turned to stone while seeking shelter from the sun, creating the depression that resembles a throne. The short but steep hike to Naustahvilft offers stunning views of the fjord and town below. It's a popular local spot.
