Definitely found my limits on this trip. Getting up at 3am to catch a feery at 4am is one of them.
So I had breakfast at the hotel. I had only 2 main options now: stay another night in Vardø and attempt to catch the next boat to Kirkenes again at 4am, or take a boat to Båtsfjord or even Berlevåg and hop on the ferry bound for Kirkenes already in the late evening. I chose the latter option and boarded the M/S Nordstjernen, built in 1956 and one of the older Hurtigruten boats still in service, at 4pm, and arrived in Båtsfjord around 8pm. Had dinner on a bench near the harbour, and waited for the Kirkenes-bound boat.
