Water information and availability
It is important that walkers bring their own water supply prior to setting out and fill up along the route. Each walker should carry at least 4 to 6 litres per day (especially on longer sections). Carrying two 1 litre water bottles and a lightweight 2 to 4 litre collapsible bladder will help to increase your water-carrying capacity on longer sections or in hot conditions. During summer and autumn, many creeks in the park are dry and become unreliable sources of water.
Water along the trail is untreated. The most reliable source of untreated water on Grampians Peaks Trail, are serviced water tanks. These tanks are listed below and are located at selected trailheads, road crossings, access points and some hike-in campgrounds. Untreated water at hike-in campgrounds, is generally supplied for cooking and hand washing. When rainfall is minimal, water supply at hike-in campgrounds cannot be guaranteed. Have a safe and reliable way to treat water for drinking. Options include bringing water to a rolling boil, cooling and drinking; chlorine or iodine tablets; handheld ultraviolet (UV) light units; and portable microfilters.
