Please note that Bomjinna Campground and the walk from Bomjinna Campground to Mount William Carpark are now officially closed. This closure is part of an initiative to enhance the experience for walkers and picnickers in the Kalymna area, offering improved access and facilities for visitors to enjoy this beautiful part of the Grampians.
Kalymna Falls - Mt William - Bomjinna is a challenging 14.5 km, grade 4 hike in Grampians National Park, Victoria. This hike typically takes around six hours to complete and offers a variety of landscapes and experiences.
Starting from the Kalymna Falls campground, the hike follows a 4WD track uphill to a signposted turn-off for Kalymna Falls. The track then descends to the base of the 15-metre falls, which cascade over the sandstone cliffs. After taking in the view, hikers return via the same route to the 4WD track, turning right to ascend to the saddle just below Boundary Gap.
At the trail junction, hikers turn right and ascend to the summit of Mount William, which stands at 1153 metres and is marked by radio masts. After exploring the summit, the descent follows a bitumen road until reaching the gate and Mount William Carpark.
The next section of the hike requires good navigation skills, as the trail from Mount William Carpark to Bomjinna Campground is almost completely overgrown. Hikers must locate the start of the Bomjinna track on the northeastern side of the carpark. Though the first 100 metres are covered in debris, the trail becomes more apparent and descends across gullies back to the Bomjinna Campground.
Mount William, rising to 1167 metres, is the tallest peak in the Grampians. The ascent involves driving most of the way up before parking and walking the rest. The climb is steep but offers fantastic views along a sealed road. As you climb, the vegetation changes with the altitude; tall eucalyptus trees on the lower slopes gradually give way to dwarfed trees and then to low, windswept bushes and grasses.
Visiting on a crisp winter's day might reward you with the sight of snow covering the sub-alpine vegetation. Climbing to the highest point in the Grampians, known as Mount William (Duwul), reveals 360-degree views of jagged mountain ranges and open plains. For a particularly stunning experience, plan your hike for just before sunset or sunrise to see the landscape bathed in beautiful colours.

Grampians National Park is part of the Gariwerd Aboriginal cultural landscape. Parks Victoria respects the deep and continuing connection that Traditional Owners have to these lands and waters, and we recognise their ongoing role in caring for Country.
Explore the natural beauty of the Grampians from its world-famous hiking trails. Discover majestic waterfalls, dazzling spring wildflower displays and awe-inspiring mountain panoramas. Cross paths with kangaroos, wallabies, emus and native birds. Heritage-listed for its Aboriginal heritage, animal and plant life, and stunning natural beauty, the Grampians National Park is one of Australia's most recognisable places. The best way to appreciate it is on one of its many world-class walks or hikes or by taking a scenic drive.
Traditionally known as Gariwerd, this region is home to the largest number of significant and ancient Aboriginal rock art paintings and shelters in southern Australia. A visit to Brambuk – The National Park & Cultural Centre will help you get the most of your trip to these rock shelters.
The Grampians draws walkers from around the world. Hike to the highest peak within the Grampians, Mount William, or explore the plethora of walks around Halls Gap and the Wonderland Range. Views from the Pinnacle are famous, but the steep walk should only be attempted by the fit. If you’re an experienced walker you’ll enjoy the unique challenge of the park’s overnight hikes. Choose from the iconic Grampians Peaks Trail, Major Mitchell Plateau or The Fortress and Mt Thackeray Overnight Hike.
There are more relaxing pursuits to enjoy in the Grampians, too. Go fishing, canoeing or kayaking at Lake Wartook, Lake Bellfield and Moora Moora Reservoir or one of the park’s many other streams and creeks.
