This tour involves some rough and uneven terrain. There are 20 uneven stone steps, without a handrail, to reach Ósvör. This tour may not be suitable for guests suffering from claustrophobia as part of it travels through a 5 km tunnel. Please note that motor coaches in Iceland can vary in overall quality from region to region. It is not uncommon that in some of the more remote areas motor coaches are somewhat older and larger than in the Capital region.
