On this trip we take you on a historical and cultural journey to Colesbukta (Coles Bay), a 4.5 km wide bay on the south side of Isfjorden. Here we find traces that go back to the time of Soviet coal mining in the 1900s. Together with Grumant, Colesbukta was one of the largest mining towns on Svalbard during the Cold War. At the end of the 1950s, more than 1,000 people had their homes and workplaces here. Colesbukta also served as a shipping port for the coal mines in Grumant, which we also will pass on our way. With our open polar circle boats, we speedily get out on the fjord and set course for Colesbukta. The Arctic landscape is prominent, and it is impossible not to be captivated by the nature that surrounds the boat as it whizzes across the Ice Fjord. We pass the mining town of Grumant before turning into the sheltered Colesbukta. On this trip we go ashore in Colesbukta, where we will walk around to explore the old buildings and look for traces of a bygone era. There are 10-12 larger buildings in the area and several ruins. The old railway line that once linked Colesbukta with Grumant can be found towards northwest and is accessible for hikers. It is clearly visible from the fjord as well, with its characteristic wooden superstructure. The area also has a rich flora, including cloudberries which otherwise is extremely rare on Svalbard. If the weather is good, we light a fire and have a small barbeque before returning to Longyearbyen. The duration of the trip is 5 hours. Age limit: 14 years. Welcome on board!
