Went to the Tourist Information and got more reliable information about places to get a tent from, and eventually bought a Hilleberg Soulo. Also asked about glacier tours to the nearby Svartisen glacier. Unfortunately, there were non scheduled for the next days and hiring a guide just for myself was well outside my budget.
There are a few caves in the area and two of them, Setergrotta and Grønligrotta, are open to the public and close to each other as well as close to the town of Mo i Rana. The last kilometer to Grønligrotta must have been the steepest climb of the journey so far (edit: it was the steepest climb of the entire journey).
Went back to the noisy campsite in the evening and pitched my new tent for the first time.
