The boat tours on Jökulsárlón and Fjallsárlón are operated from early May throughout September, depending on the weather.
The ice-cave season in the region starts mid-November and is until mid-March. Just like the boat tour it is weather dependent. Local guides who know every crevice of the glacier seek out caves formed during the winter months and offer tours. Travelers should only go on such trips under their guidance.
Electricity
Icelandic electrical standards are European (50Hz, 240 volts) so many North American electrical devices will require converters. Plugs are generally two-pinned, so devices brought in from the UK and North America will require adapters.
Difficulty Ratings
Easy, moderate, challenging … What does this really mean?
Easy – Suitable for most people in fair condition. You have to be able to walk on uneven surface and hike for at least 2 – 3 hours at a slow pace, with breaks. Trails generally in good condition, glacier travel on generally very low angle.
Moderate – Suitable for those in good condition who are able to walk for about 4 hours at a low or moderate pace. Trails generally in good condition, glacier travel partly on uneven ground.
Challenging – For someone in good hiking condition and with experience of hiking. Trails generally in fair conditions but some parts of the tour might be off track. Trails generally in fair conditions, some off the path travel, glacier/snow travel on uneven ground with some challenging sections. Pace is adjusted to guest fitness.
Demanding – For someone in very good hiking condition. Trails generally in fair conditions but large sections of the tour might be off track. Glacier/snow travel on uneven ground with some challenging sections. Pace is adjusted to guest fitness.
