No special access issues
Park your car in Barkevik or Tveidalen. Paddle your SUP or use your boat and cross the Mørjefjorden, at the eastside of Håøya. Then it is betger to paddle straight across, towards Høvdingen, and then turn around Håøya at its south side.
If you want a shorter boattrip/paddle we reccomend to paddle the norther most route, across Skolebukta. There you can find some more boulders as well, on your way to Paradisebukta (Jordebukta)
