We will be spending a few days in Bornholm. We really don’t want to rent a car—unless one of you convinces us! How are the busses for getting around to other cities? We are staying in Ronne.
They are good in general, you can find more information here: https://bornholm.info/en/public-buses/
Bikes are also a good way to get around the island.
Are there scooter rentals on Bornholm?
Do not underestimate the size of Bornholm. In the north and northeast you will find some steep hills incl. streets, e. g. Gudhjem. Most independency allows a rental car. I spent 2 weeks last June there with own car.
You can combine bus and bike if you want. The link above contains this:
The bicycle with the bus
Remember that you can bring your bike on the
regional buses of the island. BAT – din bus på Bornholm takes up to 4
ordinary bicycles per trip on a special bicycle rack.
