Blakeney Point in north Norfolk is home to England's largest Grey Seal colony. There are several seal trip providers on the north Norfolk coast. Most leave from Morston harbour, which is close to where the major seal colonies lie, around Blakeney Point. The best time to have a seal trip is mid-winter when the seals have their pups in their thousands!
See these seal trip providers for availability and more information:
You can also buy tickets from their offices in Morston, and from inside The Anchor Inn pub in Morston,
