What Is Hollow Mountain?

Hollow Mountain is one of the Grampians’ best-kept secrets. On the northern fringes of the national park is an adventurous hike to an area of hollowed-out rocks of the most vibrant oranges and browns. Certainly, from below, you’d have no idea such incredible caverns were hiding within the mountainside.

Reaching these interesting caves, which offer extraordinary window lookouts across the Wimmera Plains and beyond, involves a short 2.5km hike and a bit of steep scrambling. But, the exhilarating Hollow Mountain hike will be sure to end up one of your favourite walks of your entire Grampians trip – it was definitely one of our favourites.

The Hollow Mountain Walk is pretty straightforward. But, there are a few technical rock scramble sections to take into account. Certainly, they’re nothing too taxing, and you’ll find many people completing this out and back with no problem. Also, just be aware that in wet conditions you may find the track surface to be slippery in parts.

Hollow Mountain Walk Description

From the car park, the initial trail is open and switches from a sandy path to a steady incline over rock. As you approach the side of Hollow Mountain, the rock scramble and steep climb begins as you start to wind around the mountainside. The trail then opens up onto an exposed mountainside, where you’ll traverse the rock wall at a steep incline. So take care. It’s these sections that require caution, especially when hiking in wet conditions.

There are yellow arrows sprayed on the rock to lead your way. Follow these arrows as they spiral your path to the top. There’s another rock scramble needed to access the upper sections of Hollow Mountain. But all in all, it’s a short and exhilarating hike.

You’ll find plenty of lookout spots and cosy hangouts as you access small ‘hollow’ sections of the mountain. Indeed, we saw plenty of hikers who had snuggled down in comfortable holes for their tea break. And who can blame them?

From the summit of Hollow Mountain, you’ll find awesome views of neighbouring Mount Zero and Mount Staplyton (more on those below), as well as the rest of the mighty Grampians in the distance. As this was our last hike of the trip, it was nice to be able to look back and survey all we had conquered in the previous days.

Hollow Mountain Caves

If you’ve looked into Hollow Mountain, you’ll have seen the iconic orange-walled cave shot, like in the image below. This cave lookout is really easy to access and enjoy. The trouble Dan and I had was knowing we’d even found it.

Basically, the cave window is found about halfway up the Hollow Mountain walking trail. In fact, the trail leads you straight past the opening, which will be on your left. Somehow we missed it. In fact, we actually saw more people on the top of the Hollow Mountain, enjoying the panoramic views, rather than in this excellent natural shelter.

So, you might find you have this place to yourself. Keep an eye out to your left as you hike up, and you shouldn’t miss it. Or, just do as we did, and visit it on your way back down. It just looks like a large opening and isn’t very deep. But, it’s once you climb inside that you realise how spectacular it is.

But, as we mentioned, there are plenty of little caves and crevices to enjoy along this hike, so you can explore the ‘hollow’ mountain as much as you like.

To complete the Hollow Mountain Walk, return the way you came. Just be sure to take care on the steep scrambly sections. They can be more difficult on the way back down.

Useful Things to Know Before You Go

Below, we’ll touch on a few useful things to know about walking to Hollow Mountain in the Grampians.

How to Get to Hollow Mountain

To start the Hollow Mountain Walk, you’ll need to get to the Hollow Mountain Car Park, just off Mount Zero Road in the northern Grampians. From Halls Gap and the central Grampians, it’s around a 45-minute drive away.

You’ll need your own set of wheels to get to this trailhead and a 4WD is advisable, if possible. If not, it’s fine. We made it to the car park in a 2WD and just took it easy on some of the corrugated roads.

Hollow Mountain Car Park

The Hollow Mountain Car Park is located here on Google Maps. At the car park, you’ll find parking for plenty of vehicles, as well as drop toilets and picnic sites for your convenience.

How Long Is the Hollow Mountain Walk?

The Hollow Mountain Walk is around 2.5km long and takes around an hour to complete. But, that’s moving time. You’ll likely find you spend twice as long at Hollow Mountain as you soak in the views and explore the caves.

Hollow Mountain Walk Difficulty

Although not a long hike, the Hollow Mountain Walk is technically demanding in parts. There are a few sections of mild scrambling, though nothing too difficult – just a little physically demanding. In addition, the trail is not defined for the entire route to the summit. Instead, you’ll need to look out for painted yellow arrows to guide your route to the summit. Exploration of the caves is at your own risk and involves leaving the official way-marked route in parts.

Still, this is an enjoyable hike that is more than doable for those with some degree of hiking experience, basic physical fitness and ultimately a sense of adventure. Enjoy!

Where to Go After Hollow Mountain

After hiking Hollow Mountain, there are a few other interesting places as well as other walks you can do in the immediate area. Let’s take a look.

1. Visit Gulgurn Manja Rock Art Shelter

From the Hollow Mountain Car Park, you should certainly visit the Gulgurn Manja Shelter. It’s just an easy 15 minute walk to reach. Here, you’ll find some unbelievable examples of rock art. The site is fenced off to protect the indigenous artwork, whose name means ‘hands of young people’. The images painted on the walls include handprints and emu tracks. It’s quite wonderful.

2. Visit Ngamadjidj Shelter

If you enjoy Gulgurn, then head round to Ngamadjidj Shelter, where you can view more rock paintings. The paintings here are quite different as they’ve been painted in white clay, whereas the majority of the rest of the Grampians rock art is painted in red. You can find the shelter at Stapylton Campground. Again, it’s been fenced off to help preserve it.

3. Hike Mount Zero

  • Type: Out & Back
  • Distance: 2.8km
  • Time: 1 hour
  • Accumulated elevation gain: 150m
  • Difficulty: Moderate
  • Trailhead: Mount Zero Picnic Area
