Groby Pool, "reputedly the largest natural expanse of open water in Leicestershire" is a 38 acres (15 ha)  lake located opposite the quarry on Newtown Linford Lane.
 It is owned by Hanson quarries and managed by English Nature and became an SSSI in 1956.
 Due to lack of drainage, "it is one of the most significant wildlife areas in Leicestershire."
 The origins of the pool are debated.
 Theories include that it resulted from the damming of Slate Brook by monks from Leicester Abbey or that it was a Roman clay-pit for pottery production.

There is a public car park a few minutes' walk to the southeast, and it is possible to walk along the east side nearest the lane, although access elsewhere is restricted.
Visitors are requested NOT to feed the birds as it changes the water balance and damages wildlife.
 The pool has a strict no fishing rule.
In 2017, a number of notices were erected around the pool perimeter advising visitors NOT to paddle or swim due to blue green algae.
