Skomer has the largest puffin colony in southern Britain, along with a vast colony of Manx shearwaters, and this is the only operator that lands visitors on it. Boats leave Martin's Haven at the tip of the Marloes peninsula. Landing numbers are limited, so book ahead. Run by Dale Sailing for more than forty years, it also sells cruises around Skomer, Skokholm and Grassholm.
The office is in Neyland, but no trips leave from there. The pin is on Martin's Haven.
