The Calf of Man

Off the island's southwestern tip, across the Sound's swirling tidal race, the Calf of Man runs as nature's own annex: a bird observatory since 1959, its heather slopes host breeding shearwaters and choughs, its coves haul out Atlantic grey seals in lounging dozens, and its lighthouse generations - three towers across two centuries - stack the navigation history of a notorious coast. Boat trips circle for the wildlife or land visitors to walk the tracks between observatory, lighthouses and cliffs; the Sound's cafe on the main island watches it all across the race for those who prefer their islet with scones.

What you actually see

• The seal coves - grey seals hauled out in Atlantic dozens.
• The bird observatory - shearwaters, choughs and migration science.
• The three lighthouses - centuries of the coast's warnings.
• The Sound race - the tidal swirl between the islands.

When to go

April to September for boats and breeding birds; seal numbers peak in late summer. Sea state rules the landings - the circling trips run more reliably than the set-downs.

Honest expectations

Landings depend on swell and the wardens' terms - flexibility is part of the ticket; the islet's tracks are rough moor and the facilities a composting minimum. The Sound viewpoint delivers generously when the sea says no.
