Bornholm’s National Cycle Route 10 makes a 104.5 km loop around the island. Most of it is asphalt, with some gravel and forest-road sections. A leisurely itinerary divides the journey into four days of roughly 20–30 km; a touring, gravel or mountain bike suits the mixed surfaces.
The first stage, Rønne to Allinge, is 24.8 km long. Along the west coast, flatter woodland gradually gives way to the rocky northern landscape, with more demanding stretches along the way. Stops include Hasle, the fishing villages of Helligpeder and Teglkås, and the ruins of Hammershus. Leave time to explore.
The final 29.7 km stage from Dueodde back to Rønne reveals the gentler southern coast. It passes Slusegården’s old watermill, turns inland towards Pedersker church, then continues towards Boderne beach and the fishing village of Arnager.
The four-day sequence is Rønne–Allinge–Svaneke–Dueodde–Rønne. Plan accommodation and stops alongside the individual stage maps: short distances do not mean equal effort every day. Before booking, also check bicycle carriage conditions on your chosen crossing to the island.
