Two Mile Lake sits within Myall Lakes National Park on the mid-north coast of New South Wales, forming part of the southern waterways that connect Bombah Broadwater and Boolambayte Lake. The lake is part of an internationally recognised Ramsar-listed wetland system, one of the largest fresh-to-brackish coastal lake networks on the New South Wales coast.

The primary access point for paddlers is Korsmans Landing campground, which has a boat ramp and serves as the standard launching point for trips across the lake. Despite being an inland waterway, the lake system is tidal, and the broader Myall Lakes area is known for variable wind conditions — conditions can range from glassy calm to challenging chop, so paddlers should plan accordingly and monitor forecasts before heading out.

Two Mile Sands campground, located on the far shore, is accessible only by boat and represents the main destination for paddlers crossing the lake. Seven campgrounds in total surround Two Mile Lake, making it well suited to overnight and multi-day paddle-camping trips. The campground at Two Mile Sands is small and remote, with the shoreline fringed by angophoras and paperbarks.

Birdlife is a prominent feature of the lake. Black swans, white egrets, and large groups of coots are regularly observed along the shoreline. The surrounding bushland and waterways are active with birdsong, particularly in the evenings. The broader Myall Lakes system supports a wide range of wildlife and natural scenery, including eucalyptus forests and open water stretches.

Activities available on and around Two Mile Lake include stillwater kayaking and canoeing, fishing, swimming, walking, and birdwatching. The lake is also used by motor boats, dinghies, and trailerable sailboats. Paddlers should be aware they are sharing the water with motorised vessels. Given its location within a national park, standard national park regulations apply, and camping at Two Mile Sands requires arriving by water.
