Latest Itinerary

Please note that the following cruises are a guide to the cruises we offer. Although the majority of cruises are planned as wildlife cruises, should there be sufficient demand for an alternative cruise type on particular dates, we will attempt to provide the cruise you desire.

Flexibility does depend on existing bookings, so obviously, if you can fill the boat with your party (minimum 8 people), it will be easier to privide you with the cruise you want!

Exact destinations will depend on tide and weather conditions forecast or on the day, and will be at the discretion of the Skipper. Overnight Cruises from Mackeral Quay will have the alternative of a Cleddau Cruise under almost all weather conditions.

Cruises for 2007 embark from Mackerel Quay, Milford Haven.
