One of the most popular activities in the region is fishing. At most camp sites you can rent a small boat. In addition to fishing from a boat there are plenty of nice spots from land. The best one is of course Saltstraumen.
In the southern part of Kystriksveien you will find the Namsen River which is known for large salmon.
Anyone being in a boat or down by the sea must show caution because even if the weather is fine in the morning it does not mean that it will stay that way all day. Check the weather forecast or ask a local before you leave. If the clouds darken and start to gather, it is a good idea to head back. It is smart to tell someone where you are going. Remember lifejackets!
Svartisen Glacier is one of the most interesting walks and here you can join an organised tour. In the mountains around Svartisen, Glomfjordfjellene, you can find excellent trips which you can take on your own.
If you visit Torghatten Mountain you should walk through the hole and around the mountain. Outside Sandnessjøen you can walk in the mountains De syv søstre (The Seven Sisters).
In Steinkjer you can follow the 10 kilometre-long trail into the mid-point of Norway, close to Skjækra National Park.
Kystriksveien is excellent for biking. You can bike the entire route from Steinkjer to Bodø in approximately 7 - 10 days. There are plenty of opportunities for daytrips as well. From Namsos you can make a round trip on the island, Jøa.
From Brønnøysund and Sandnessjøen you can go island hopping to Vega, Herøy and Dønna.
Bike rental is available at the tourist information offices in Steinkjer, Namsos, Brønnøysund, Sandnessjøen and Bodø.
