Durras Lake is a coastal estuary stretching approximately six kilometres, with a total water area of around 3.2 square kilometres, located within Murramarang National Park on the New South Wales South Coast in the Eurobodalla region. The lake is classified as an intermittently closed and open lake/lagoon (ICOLL), meaning its ocean entrance opens during periods of high rainfall and closes naturally during dry periods. This dynamic entrance condition affects water levels and tidal movement throughout the system.

Two launch points serve paddlers: the official boat ramp at the end of Lakeside Drive, South Durras, and an informal boat ramp at the end of North Durras Road, North Durras. A full circumnavigation of the lake covers up to 15 kilometres and can take several hours. The lake features numerous tributaries and shallow bays, making it well suited to exploration by kayak or stand-up paddleboard. Sit-on-top kayaks are particularly practical given the shallow nature of much of the lake, which can restrict access for larger motorised vessels.

The lake forms part of the Batemans Bay Marine Park, established in April 2006. Sanctuary zones exist in the upper sections of the lake, marked by yellow buoys, where fishing and other extractive activities are prohibited. The remainder of the lake is designated as a Habitat Protection Zone. Paddlers should be aware of these boundaries when exploring the upper reaches.

Wildlife along the lake includes sea eagles, whistling kites, kangaroos along the shoreline, stingrays, and fish. The surrounding spotted gum forest of Murramarang National Park frames the paddling environment throughout. The lake is described as one of the most unpolluted waterways on the east coast of Australia.

Morning paddling is generally preferable during summer months, as winds tend to be lighter earlier in the day. The lake is considered suitable for paddlers of varying experience levels given its sheltered, shallow character. Kayak and SUP hire is available locally through operators based at South Durras, with guided half-day lake tours also on offer. The lake also serves as a crossing point for hikers on the Murramarang South Coast Walk, and kayak crossing assistance is available from local operators when the entrance is open to the ocean.
