Val de la Mare, located in Jersey, Channel Islands, encompasses both a significant reservoir and a notable arboretum, offering a tranquil escape with beautiful walking trails. The reservoir, constructed in 1962, is Jersey's second largest and plays a crucial role in the island's water supply, holding approximately 938.7 megalitres of untreated water. It is owned and managed by Jersey Water and is open to the public for recreational enjoyment throughout the year.

The Val de la Mare Arboretum, situated above St. Ouen's Bay, is a haven for nature enthusiasts, featuring ten diverse tree collections from around the world, including many rare and endangered species. Established in 1975 and now managed by Jersey Trees for Life, the arboretum is rich in birdlife and other fauna, such as red squirrels, lizards, and various insects. Visitors can explore several walking routes, the longest of which is a 2.8-mile circuit, and enjoy the peaceful surroundings and scenic views.

Big dam at the end of the reservoir with footpaths all the way over and round and
surrounded by nature absolutely lovely for a summer evening walk! They have held a few festivals at the bottom of the dam too

Nice to walk around. Peaceful. Takes just over an hour without rushing. We found our way from the beach nightclub direction. Got hopelessly lost when we tried to access from the landward side using Google - ended up on a very narrow road which led past several houses before finishing on someone's driveway!
