Day's Lock is a lock on the River Thames near Dorchester-on-Thames, Oxfordshire, England on the Dorchester side of the river. The pound lock was built in 1789 by the Thames Navigation Commissioner. The lock is across the river from the small village of Little Wittenham and is overlooked from the south by the hills of Wittenham Clumps, with a particularly good view from Round Hill. The weir runs straight across the river from the other side of the lock island. Day's Lock is the main gauging station for the measurement of the water flow in the River Thames.

Little Wittenham Wood has been designated as both a Site of Special Scientific Interest (SSSI) and a Special Area of Conservation (SAC), reflecting its international importance for wildlife. The nature reserve is particularly important for the endangered species, the Great Crested Newt. This shy amphibian uses the many ponds within the nature reserve to breed, but it spends the majority of time in the surrounding woodland. Tucking itself quietly away in safe and secure hidden spots, you have to search carefully to find them. Much easier to spot are the dragonflies and damselflies which hover around the ponds. If you wander down to the bird hide, at the river’s edge, you might be lucky enough to catch a glimpse of Kingfishers or Otters.

It is a fantastic hide with views over the fields & ponds. DOGs are NOT allowed. This also means that you cannot use the direct footpath towards Beckley if you have a DOG. Instead you have to take the path via the RSPB car park, which adds 2k to the walk if you go back to the footpath, rather than follow the road up to the Abingdon Arms at Beckley
