Small group Northern Lights VIP Adventure with Pickup

September to April, when the nights are dark enough. Within that, late September to March gives the longest dark hours, and the equinox months, September and March, often have active skies. There are no lights in June or July; the sky never gets dark. Anyone selling you a June lights tour is selling you a bus ride. Give yourself at least three nights, because clouds, not the aurora, are the usual reason people miss them.

No. Nobody can promise them, and we will not. Two things have to line up: a clear sky and solar activity. Guides check the cloud forecast at vedur.is and drive to gaps, which is the real value of a tour over standing outside your hotel. What most operators do promise is a free second attempt if the lights do not show. Check the exact retry policy on the tour page, because the number of retries and the validity period vary.

Bus, if you want the best odds. A minibus can drive an hour inland to find a clear patch; a boat stays in Faxaflói and sees whatever sky is over Reykjavík. Boats are shorter, about two hours, and pleasant with hot chocolate, and Reykjavik Sailors' cruise (/experience/6637/) includes a free retry. For a serious hunt, a small-group minibus like BusTravel's (/experience/150646/) or a 4x4 tour (/experience/1088067/) is the better bet.

Yes, on strong nights. The city is small and the sky over the sea to the north is fairly dark. Grótta lighthouse at the western tip and the Ægisíða shoreline are the usual spots, twenty minutes' walk from the centre. On average nights the street lights drown out a faint aurora, which is why tours drive out. If the forecast shows high activity and clear sky, walk to Grótta first and save the tour money.
