Our coasts are one of the most fascinating places to go wildlife watching. There are unusual birds in the sky and interesting plants cover the ground. But the most exciting wildlife is hiding under the water. Seals are just one of many marine creatures that continue to enthral.

The best time to spot a seal is when the tide is out. Grey seals prefer the wind and wave swept rocky shores, while the Common seal favours calmer waters. Common seal pups are born in June or July and can take to water immediately. Grey seal pups are born white furred between September and November, remaining on land for 3-4 weeks until weaned.

This autumn the National Trust shares its top six seal watching spots:

Lundy Island, Devon
Lundy was designated the first Marine Conservation Area and is teeming with wildlife. Seals can be seen all around the island and even come into the landing bay for an inquisitive look at the visitors. Of further interest to nature-lovers are the migratory seabirds, heathland and grassland habitat and the Lundy ponies. During the summer months you may also spy basking sharks off the coast.

Farne Islands, Northumberland
The Farne Islands lie two to three miles off the Northumberland coast. As well as being the most famous seabird sanctuary in the British Isles they also have a large colony of Grey seals. It is estimated that there are between 3,000 – 4,000 seals in the area so you should get to see at least one!

Strangford Lough, Northern Ireland
This is one of the most important breeding sites in Ireland for Common seals, despite a decline in numbers. For the best views of the seals look out to the rocks just off the shore. Porpoises and otters are also regularly seen in the water here.

Blakeney Point, Norfolk
Blakeney Point is a 3 1/2 mile long sand and shingle spit. Both Common and Grey seals can be seen here. As well as the seals there are breeding terns and migrant birds passing through.

Cape Cornwall, Cornwall
This rocky patch of coastline is perfect for the Common seal. They are often seen in the water or hauling themselves onto the rocks for a rest. A climb up the Cape headland offers panoramic views of Lands End, Sennen Cove, Brisons rocks and the Isles of Scilly.

North Pembrokeshire, Wales
This area of coastline is characterised by magnificent bays and spectacular headlands. The best way to spot a seal on this stretch of coast is to set off on a walk through the Pembrokeshire National Park. If you are lucky you might just see newborn seals sheltered in the quiet coves.
