'Ello chaps!Batservice Sightseeing (Boat Service Sightseeing) is located in the heart of downtown Oslo (near Akershus Fortress). They offer a variety of "fjord" sightseeing tours.I say "fjord" because the region is within a "fjord" but the fjords one would imagine being in Norway are found elsewhere, such as near Bergen.Despite this, it's a great two hour tour, and costs about $40 USD. It's money well spent.You get great views of Oslo from the water, getting to see the water shore attractions such as the Oslo Opera House, but also the near by islands and summer homes.Snacks and drinks are available for purchase on board. You can pre-purchase tickets online or in person --- or on the spot, although some tours may fill up.Seating is on an open deck and available first come first serve, so be early for a good spot. They suggest one half hour prior to departure time.Overall I give Batservice Sightseeing 5 stars out of 5.
