The boat ramp at Old Adaminaby is the primary concrete launch point on Lake Eucumbene, and is noted as the longest ramp in New South Wales.

Its grooved concrete surface provides traction and is suitable for a range of trailered vessels, from smaller craft to larger boats such as 6-metre reef boats and centre consoles. The ramp remains accessible even under light snow cover.

A secondary, more acutely angled ramp sits nearby, near the old ruins, and sees use particularly when lake levels fluctuate. Water levels can affect how far vehicles must reverse to reach the water.

Recent upgrades have improved launching conditions at the site. No toilets are available at the ramp, so visitors are advised to come prepared with food and drinks.
