Allenvale Mill Camp Site is a walk-in tent-only campground set on pleasant grassed hillside slopes above the Saint George River, deep within Great Otway National Park near Lorne, Victoria.

The site is well shaded by Manna Gums and surrounded by tall forest, with the carpark just 200 metres away — no vehicle access to the sites themselves. It offers 20 unpowered campsites, each accommodating up to six people, along with toilet facilities.

Fires are strictly prohibited at all times, and pets are not permitted. The location provides excellent access to nearby walking tracks, including the St George River Walk and the trail to Phantom Falls.

As one of the closest bush campgrounds to Lorne, it serves as a solid base for day hikes in the surrounding park. Booking is required through Parks Victoria.
