Burrill Lake is a coastal lake located in the South Coast region of New South Wales, approximately five kilometres south of Ulladulla and around three and a half hours south of Sydney. The lake sits within the Milton-Ulladulla district of the City of Shoalhaven local government area, surrounded by natural bushland and forest cover. The lake has two distinct basins, with the upper parts offering calmer, quieter water and the western arm extending into Meroo National Park.

For paddlers, the lake accommodates kayaking, canoeing, and stand-up paddleboarding. The upper reaches of the lake, around Kings Point, are particularly well suited to flat-water paddling, offering calm conditions away from motorised boat traffic. The western arm provides a route into Meroo National Park, where the Burrill Lake Western Arm picnic area sits alongside the Giriwa walking track, making it a natural destination for a day paddle. A route exploring Stony Creek and then the western basin is one documented paddle option, and the trip can be shortened to suit the paddler's preference.

Two public boat ramps serve the lake: the Northern boat ramp on Kendall Crescent and the Maia Avenue boat ramp. Paddlers should be aware that the upper lake is also used by the local water ski club, which has its own picnic area and launching ramp at Kings Point, so motorised vessel traffic is a consideration in that area.

The lake is an estuary system supporting a variety of fish species including flathead, bream, whiting, luderick, mullet, estuary perch, and blue swimmer crabs, with occasional mulloway also present. Wildlife such as dolphins and pelicans have been observed on the water. The lake's foreshore includes a Lions Club-maintained barbecue and parkland area. Kayak hire is available locally through operators including WOW Watersports and Walking On Water Hire, the latter also offering guided tours and stand-up paddleboards. Accommodation options near the lake include caravan parks, cabins, and holiday rentals.
