We are looking to book a tour of the volcano in Reykjavik but need to book the 8am tour in order to be back by 2:00 ship departure. I'm wondering if anyone has ever booked this tour and how long from pick up to drop off it actually took? The tour operator said we should be back between 1 and 1:30. I dont mind cutting it close usually, but thought I'd see if anyone has done this before. Thanks! Robi
