The Hisøy bike route is a nice route that takes the tour from the center of Arendal and out to the ferry at Kolbjørnsvik. The route has possibilites for deviances from the main route and directions from Kolbjørnsvik and back to Arendal.
The Hisøy route starts from the center of Arendal, westbound along the docks past Kittelsbukt and over to Svinodden, before you take the freeroad (Strømsbuneset) up to state road number 420 towards Fevik, all the time on sidewalks that are adapted for walking and bicycling along 420. By the roundabout at the middle of the island, there is now a RIMI-store where you take left towards Hisøy church.
Here you may choose to take the trip to Tangen. If you want to go to Tangen, you follow state road 420 further towards Fevik until there is a sign (Tangen) where you go right. There are sidewalks specifically for biking and walking almost all the way in past Tangen avenue (Tangen allé), and the way past the industrial buildings and down the the free area to the right is lightly trafficated. At Tangen there are trashcans, toilets, benches and a playground for the kids. Sandstranden (a beach) is perfect for families with children and the water is a mix of sea- and freshwater. (3.5 kilometers extra)
If you do not want to go to Tangen, you could continue by the church where the route goes on towards Kolbjørnsvik. Here there is a possibility to stray off the route towards Stølsvika. The free area at Stølsvika has signs to show you the way, which goes past the church and is rather narrow at times. There is a big parking lot by the free area, and stølsvika is accustomed for visitors with toilets, trashcans, a volleyball net, a kiosk and two nice beaches in addition some rocky shores. Onwards Havsøyveien, past the parking lot at Stølsvika, leads to the docks at Havsøy which is a beautiful sight in both summer and winter. (2.5 kilometers extra)
If you do not wish to go to Stølsvika, you could follow the signs towards Kolbjørnsvik 3. On the middle of Trommesletta there is a narrow road up towards the right (Gamle Sandvigve, 600 meters) which leads you over to the eastern part of Hisøy on asphalted roads through meadows and forest. At Sandvika one can take a small trip up the way marked by 30 past traditional south-Norwegian houses and back to the turnpike. From here, take the way towards Kolbjørnsvik all the way to where the ferry leaves from.
If you wish to travel back to Arendal, you follow the road to the left on the top of the hill down towards the ferry. Se the sign marked 420, choose the road to the right (not towards Hisøy kirke). This will eventually lead you to state road 420 by Strømmen, where you take to the right towards Arendal. (4.5 kilometers extra)
