70th Anniversary Photo Competition70th Anniversary Photo Competition

Fancy seeing your own Dartmoor photo on an
OS Explorer Map?

In 2019, we created a poster to commemorate 70 years since the 1949 Act of Parliament that began the family of National Parks in Great Britain. This year, we are holding photo competitions to celebrate the 70th anniversary of two of their oldest landscapes – the Lake District and Dartmoor National Park.

Having already run the Lake District competition, we are now teaming up with our friends at Dartmoor National Park to find a front cover image for our new edition OL 28 Dartmoor OS Explorer map.​

Due to the latest lockdown and government advice to stay local, please do not travel to Dartmoor to take photos. From the comfort of your own home, delve into your memories, pick your favourites, and submit them into our cover competition.

Lake District 70th Anniversary

Dartmoor 70th Anniversary

Join us this year in celebrating 70 years of Dartmoor being cared for; its wildlife protected and its cultural heritage enhanced.

This inspirational landscape became a National Park for everyone on 30 October 1951 and is owned and cared for by organisations, farmers, and other private landowners.

It is known for its granite tors, its bogs and mires, and its epic views across wild open moorland. Past lives are traced into it by prehistoric ruins, abandoned medieval villages and the remains of tinworkings. Rivers cut through deep wooded valleys, haymeadows bloom and traditional farming goes hand in hand with the land.
