Weather permitting, boats run from Martin’s Haven to Skomer Island, a 722-acre flat-topped island whose rich birdlife and spectacular carpets of wild flowers make it perfect for birdwatching and walking.

Though no landings are permitted, fast cruises leave from Dale to loop around Skomer and Skokholm Island, a couple of miles south of Skomer and far smaller, more rugged and remote, noted for its cliffs of warm red sandstone. Britain’s first bird observatory was founded here in 1933, and there are still huge numbers of petrels, gulls, puffins, oystercatchers and Manx shearwaters.

The same company also offers cruises out to the tiny outpost of Grassholm Island, more than five miles west of Skomer. Some 80,000 or so screaming gannets nest here, and though they do not land, boats stop to watch the wildlife.
