$399.83 per adult
Make an adventurous descent inside the remains of Iceland’s dormant Thrihnukagigur volcano during this 5-hour, small-group excursion from Reykjavik. Traverse the surreal landscapes of Iceland’s countryside on your way to the Blue Mountains, hiking through the area’s craggy lava fields.

This small-group excursion, limited to 18 guests, also includes all necessary safety equipment and round-trip hotel transportation.
