Please note: The River Ouse in York can occasionally rise to levels that can have an impact on this cruise’s daily operations after periods of heavy rainfall in the catchment area upstream. The local operators will always attempt to sail for as long as it is safe to do so. There can come a point where their smallest boat can no longer fit underneath the bridges. Depending on the height of the river, they may not be able to sail at all. In this instance, you will either be eligible for a full refund or your ticket(s) will happily accepted on another date during your stay if sailing is possible.
