Real racing boats are often moored here. Lots of speed, little comfort.

Great views. A couple of short sections are too sandy for narrow tyres.

We recommend taking the short ferry crossing. This saves you the detour over the bridge to the north. This is a good option if there aren't too many cyclists waiting. The ferry only takes three bikes at a time. Payment is made on board, in cash or by debit card.
