Insh Marshes, Scottish Highlands

Managed by the Royal Society for the Protection of Birds (RSPB), the Insh Marshe is part of the Cairngorms National Park in the Scottish Highlands. It lies between the cities of Perth, Aberdeen and Inverness and is a great stopping point on any Scottish road trip.

Lundy Island, Devon

Sitting pretty off the North Devon coast, you will find Lundy, a tiny island in the spot where the Bristol Channel meets the Atlantic Ocean.

Lundy Island, though small at only three miles long and one and a half miles wide, contains a variety of wildlife. Those who make the journey may be lucky enough to see wild ponies, seals, bottlenose dolphins, basking sharks, and harbour porpoises.

Visitors are taken over to the island by the MS Oldenburg which sails three times per week in the summer months, leaving from the seaside towns of Bideford or Ilfracombe.

This area of the UK is filled with fantastic beaches making North Devon holidays an ever-popular choice for families, couples, and groups.

Blacka Moor, South Yorkshire

Lying on the Eastern Peak District Moors, you'll find beautiful Blacka Moor, designated as a Site of Special Scientific Interest and home to red deer, the UK's largest native animal, as well as bilberry bumblebees and a wide variety of birds.

Nearby, you'll find the pretty towns of Bakewell and Matlock, as well as Chatsworth House, which doubled as Pemberley in the Pride and Prejudice film starring Keira Knightley and Matthew Macfadyen.

A holiday in the Peak District will keep nature, history, and literary fans well occupied.

Skomer Island, Pembrokeshire

One of the UK's true wildlife treasures is Skomer Island in Wales. This tiny but stunning island is home to guillemots and razorbills while seals swim in the waters around the islands, but the bird that everyone goes there to see is the puffin.

These cute and iconic birds are used to visitors, so you should be able to get a good view of them. However, the island is only open from April to September as the puffins are only in residence during the summer months, so you may be disappointed if you visit at any other time.

July is known to be the best month to see puffins, whilst May is when the bluebells are in full bloom.

Sandscale Haws National Nature Reserve, Cumbria

In the Northwest of England, close to the Lake District National Park, lies Sandscale Haws National Nature Reserve, a coastal reserve with beautiful views over the Duddon Estuary.
