Honestly, most people think Australia is just red dirt, deadly snakes, and beaches. They’re usually shocked to find out we have an alpine range that actually gets more snow than Switzerland. That’s Kosciuszko National Park for you. It’s huge. We're talking 690,000 hectares of jagged granite, glacial lakes, and some of the rarest bogs on the planet.
It’s not just a place to go skiing in July.
If you head down to the Snowy Mountains in New South Wales, you’re stepping into a landscape that has been managed by the Ngarigo people for tens of thousands of years. It’s old. Like, really old. While the Alps in Europe are young and pointy, the mountains in Kosciuszko National Park are weathered and rounded, ground down by millions of years of wind and ice.
The Mount Kosciuszko Summit "Disappointment"
Here’s the thing. If you hike to the top of Mount Kosciuszko expecting a razor-sharp peak that pierces the clouds, you’re gonna be let down. It’s basically a big, rocky hill. At 2,228 meters, it’s the highest point on the Australian mainland, but the walk from Thredbo is so gentle that you’ll see toddlers and grandmas doing it in sneakers.

Don't let the "easy" walk fool you though.
The weather here is a total wildcard. I’ve seen it go from a sunny 25°C to a horizontal sleet storm in about twenty minutes. People get hypothermia in the middle of summer because they think "Australia" equals "hot." It doesn't. Not up here. If you’re taking the 13-kilometer return trip from the top of the Kosciuszko Express Chairlift, you need layers. Even if the sky is blue.
If you want the real experience, skip the main path. The Main Range Track is where the actual magic happens. It’s a 22-kilometer loop that takes you past Blue Lake. This isn’t just any puddle; it’s a cirque lake carved out by a glacier. It’s one of only four cirque lakes on the entire mainland. The water is a deep, icy turquoise that looks like it belongs in the Canadian Rockies.
Feral Horses and the Fight for the High Country
We have to talk about the brumbies. It’s the biggest controversy in the park right now. You’ll see them—beautiful, wild horses roaming the plains near Long Plain or the Cascades. They look iconic. They look like something out of The Man from Snowy River.
But they’re also a massive problem for the environment.
Conservationists and the NSW National Parks and Wildlife Service (NPWS) are currently in a high-stakes battle over how to manage them. The problem is their hooves. Australian plants didn't evolve with hard-hoofed animals. These horses trample the delicate sphagnum bogs. Those bogs act like giant sponges; they hold water and release it slowly into the Murray and Snowy River systems. When the horses smash them, the bogs dry out, and the whole ecosystem collapses.
The government is currently carrying out aerial culling to bring the numbers down from an estimated 17,000+ to around 3,000 by mid-2027. It’s brutal. It’s emotional. Locals are divided. Some see the horses as living heritage, while others see them as an invasive species destroying the home of the Corroboree Frog and the Broad-toothed Rat.
It’s messy. It’s complicated. It’s exactly the kind of nuance people miss when they just look at a postcard.
The Secret Season: Why Summer Wins
Skiing is fine. Perisher and Thredbo are great if you like $20 burgers and lift lines. But Kosciuszko National Park in January? That’s the real pro move.
The wildflowers are insane.
Between December and February, the alpine meadows explode. You get Silver Snow Daisies, Billy Buttons (those yellow pom-pom looking things), and Mountain Gentians. It looks like a Windows screensaver. Plus, you can actually see the ground.
Best Spots for the "Summer" Crowd
- Yarrangobilly Caves: This is in the northern part of the park. Most people stay south near Jindabyne, so they miss this. There’s a thermal pool that stays at a constant 27°C year-round. You can swim in it while there’s snow on the ground nearby.
- Blue Waterholes: Located at the end of a long dirt road in the northern High Plains. The water is incredibly clear because of the limestone, and there are these massive gorges you can hike through.
- Island Bend: A perfect spot for camping if you want to avoid the crowds at the main resorts. It’s right on the Snowy River.
- Charlotte Pass: The highest permanent settlement in Australia. In winter, you can’t even drive here; you have to take a snowcat. In summer, it’s the gateway to the best hiking trails.
The Mountain Pygmy-possum and the Bogong Moth
There’s a tiny resident of Kosciuszko National Park that most people will never see. The Mountain Pygmy-possum. It’s Australia’s only hibernating marsupial. For years, scientists thought they were extinct until one was rediscovered in a ski club lodge in 1966.
They rely on Bogong Moths.
Every year, billions of Bogong Moths migrate from Queensland and NSW to the caves in the Snowy Mountains to escape the heat. They’re like a high-protein buffet for the possums. But recently, the moth numbers have crashed. Light pollution in the cities distracts the moths on their flight path, and droughts in their breeding grounds mean fewer make it to the mountains.
If the moths don't show up, the possums don't eat. It’s a fragile chain. When you’re walking the trails, you’re walking over the roof of their world. It makes you realize how much is happening under the rocks while you’re just trying to get a selfie at the summit.
Survival is Not Optional
Let’s get real about safety. Kosciuszko is "accessible," but it's still wilderness.
People die here.
Usually, it’s from exposure. The "Snowies" are notorious for "Whiteouts." This is when the fog and snow get so thick you can’t see your own feet. You lose all sense of direction. If you aren't carrying a Personal Locator Beacon (PLB), which you can actually borrow for free from the NPWS visitor centers in Jindabyne or Tumut, you’re taking a massive risk.
Navigation is tricky because the terrain is so undulating. Everything looks the same when the mist rolls in.
The Hydro-Electric Giant
You can't talk about this park without mentioning the Snowy Mountains Scheme. It’s one of the most complex hydro-electric systems in the world.
Think tunnels. Massive ones.
The scheme diverts water from the Snowy River through the mountains to the west to power turbines and provide irrigation for the Murray-Darling Basin. It was built between 1949 and 1974 by over 100,000 people from 30 different countries. It’s basically what built modern, multicultural Australia.

You’ll see the dams everywhere—Lake Eucumbene, Jindabyne, Tantangara. They look like natural lakes, but they’re all man-made. If you’re into engineering, the Snowy 2.0 project is currently underway, drilling even more tunnels to increase the pumped-hydro capacity. It’s a polarizing project because of the environmental footprint inside a national park, but it’s a central part of Australia’s renewable energy future.
Mountain Biking is the New Skiing
Thredbo has pivoted hard into mountain biking. They have the "Cannonball Downhill," which is exactly as terrifying as it sounds. If you aren't a pro, the Thredbo Valley Track (TVT) is much better. It follows the river from Thredbo down to Lake Crackenback.
It’s about 35 kilometers of flowing singletrack.
The bridges are high-quality, the views of the river are stunning, and you can get a shuttle back up the hill so you don't have to pedal against gravity the whole time. It’s honestly one of the best ways to see the lower-altitude bushland of the park.
How to Actually Plan Your Trip
Don't just turn up. You need a park pass. It’s about $17 per vehicle per day in the off-peak, but it jumps to $29 during the ski season.
If you're camping, book ahead. The popular spots like Tom Groggin (where you’ll see heaps of kangaroos) fill up fast in the summer.
Also, watch out for the flies. Alpine March Flies are no joke. They’re huge, they’re loud, and they bite through leggings. Bring the heavy-duty DEET repellent. Seriously.
Essential Gear Check-list:
- Hydration bladder: At high altitude, you dehydrate way faster than you think.
- Proper boots: The granite is sharp. Your Kmart sneakers will get shredded.
- Sunscreen: The UV at 2,000 meters is brutal. You’ll fry in 15 minutes.
- Offline Maps: Reception is basically non-existent once you leave the main resort hubs. Download AllTrails or use a paper map.
- A PLB: Just go to the visitor center and borrow one. It’s free.
The Cultural Landscape
We often ignore the history of the cattlemen. Before it was a national park, the high country was used for summer grazing. You’ll find old huts scattered everywhere—Seaman’s Hut, Cascade Hut, Teddys Hut.
These aren't just ruins.
They were life-saving shelters for stockmen caught in storms. Seaman’s Hut was actually built as a memorial to two skiers who died of exhaustion in 1928. It’s made of solid rock and is still open today for emergency use. If you’re hiking the Main Range and the weather turns, that hut is your best friend.

But even before the cattlemen, the Ngarigo and Wolgalu people were here. They traveled to the high country every summer for the "Bogong ceremonies," gathering the moths and meeting with other nations for trade and marriage. When you stand on the summit of Kosciuszko, you aren't just standing on a mountain; you’re standing on a place of immense spiritual significance.
Practical Steps for Your Visit
First, decide on your base. Jindabyne is the "hub," but it's a 30-minute drive to the park entrance. If you want to be in it, stay at Charlotte Pass or Thredbo, but be prepared to pay a premium.
Second, check the NPWS website for "Live Alerts." Fires, snow closures, and feral animal control operations happen all the time.
Third, if you're driving in winter, you must carry snow chains unless you have a 4WD or AWD vehicle. Even then, sometimes they make everyone fit them. The rangers don't play around with this. If you don't have them, they’ll turn you back at the gate.
Finally, leave no trace. This sounds like a cliché, but the alpine environment is incredibly slow to recover. A single footstep off the track can destroy a plant that took ten years to grow. Stick to the metal mesh walkways near the summit—they’re there to protect the soil from erosion.
Kosciuszko National Park is a place of extremes. It's where Australia feels most like another planet. Whether you're there for the sheer adrenaline of a downhill bike track or the quiet solitude of a glacial lake, just respect the scale of the place. It's bigger than you, and that's exactly why it's worth the trip.
Get your park pass online before you leave, pack more water than you think you need, and always, always tell someone where you're going before you head out into the Main Range.
