The Sti 100 is a super nice trail that stretches over a huge area. From this sty branch off many others. The Sti 100 goes from just above Saltum Strandvej to Hune.
The main route - STI 100 - runs parallel to the coast between Blokhus and Kettrup Bjerge near Sylviavej. From here you can continue the North Sea Trail to Grønhøj, then the North Sea Trail leads along the beach to Løkken. You can use the Redningsvejen between Grønhøj and Nybæk Plantage from Løkken. The route on Redningsvejen is not marked but easy to find. Paths 1-40 will bring you from the STI 100 to the beach. The Blokhus Tourist Office has a card with the STI 100 for five (5) DKK.
