December 2025 will always remain one of my most magical travel memories. My husband and I had planned a 10-day Finland trip, and like every excited winter traveler, our hearts were set on chasing the northern lights. But little did we know that Lapland had so much more to offer beyond the green dancing sky.
We spent 3 nights in Rovaniemi, the official hometown of Santa Claus and the perfect base for countless Arctic adventures. From ice breaker cruises, snowmobiling, husky safaris, and reindeer farms to lesser-known gems like the Korouoma Canyon trek, there is so much you can pack into your Lapland itinerary.
And since both of us are absolute trek lovers—and I had always dreamt of doing a snow trek—there was no way we were skipping this one. Looking back, I’m so glad we didn’t.
What is Korouoma Canyon?
Korouoma Canyon is one of Finland’s most iconic geological formations, located in the Posio region. This dramatic, steep-sided fracture valley was created millions (almost a billion!) of years ago due to tectonic movements. Over time, glaciers carved it deeper, leaving behind a breathtaking canyon lined with cliffs up to 130 meters high.
In winter, these cliffs transform into giant frozen waterfalls—a playground for ice climbers and a visual treat for trekkers. Korouoma is part of a protected nature reserve and is famous for its three main waterfalls:
- Jaska Jokunen
- Mamman Märkäpuku
- Ruskea Virta
All of them freeze completely, turning into towering blue-white ice curtains that look like nature’s artwork.
Walking through this ancient canyon, surrounded by snow-laden trees and absolute silence, feels like stepping into a winter fairy tale.
How to reach Korouoma Canyon from Rovaniemi
Korouoma Canyon lies about 110 km from Rovaniemi, roughly a 1 hour 45 min – 2 hour drive depending on road conditions.
Most people, including us, initially think:
“Let’s rent a car and do this trek ourselves.”
But here’s the truth:
Challenges of doing it on your own
- Car rentals in Lapland in December are extremely expensive, even when shared among 4 people.
- Snowy roads can be tricky, especially if you’re not used to driving on icy surfaces.
- The total journey is tiring: ~3 hours of driving (round trip) + 3–4 hours of walking in snow.
- Waymarkings sometimes get buried under thick snow, making it easy to lose the trail without a guide.
- In winter, daylight is limited so that timing errors can become risky.
Because of all this, a guided tour is genuinely the safest and most convenient option.

Most guided tours operate with:
- Minimum 2–4 pax requirements

The Trek Experience
The Korouoma trek follows a circular loop, roughly 5–6 km depending on the snow. It usually takes 3–4 hours with stops for photos, warming breaks, and the barbecue.
What you see
You’ll get to witness:
- 2–3 main frozen waterfalls
- Countless smaller ice formations
- Snow-covered forests
- Steep cliff views of the canyon
The trail has a mix of:
- Gentle walks
- Slight descents into the canyon
- A few slippery sections
- A steep 1 km uphill climb towards the end
Your shoe spikes will be your best friend here!
A fun Lapland moment
Our guide pointed out some grassy moss that reindeer love munching on. And yes—you can taste it too.
It felt strange, slightly crunchy, but hey… when in Lapland!
Barbecue break
Halfway through the trek, there’s a cozy campfire barbecue hut where guides grill sausages (vegetarian options too), serve hot berry juice, and let you warm your hands.
After this break, the last kilometer is uphill but feels manageable thanks to all that warm food and adrenaline.
Avoid stopping too long here, or your body may cool down and make the uphill climb tougher.
Important essentials & tips for Korouoma
Having experienced the trek in deep December snow, here’s everything I wish someone had told me:
Do NOT wear heating pads (especially on your feet!)
The warmers make your feet sweat → sweat becomes moisture → moisture becomes ice → higher chance of frostbite.
Stick to good layering.
Layer properly (3–4 layers)
Base layer: Thermal top & bottom
Mid layer: Fleece or wool sweater
Insulation layer: Down jacket
Outer layer: A windproof & waterproof shell
Your guided tour can provide the top two layers if needed.
Wear shoe spikes
Even if you’re confident, even if you “don’t feel like it”—please wear them.
They will save you from endless slips.
Start early
Aim to start between 8–9 AM.
In December, sunset is around 3–4 PM, and you do not want to trek downhill in the dark.
Keep moving
The trick to staying warm is continuous movement.
Let your body naturally adjust to the cold.
Washroom break
There’s a K-Mart/gas station about 45 minutes before Korouoma Nature Reserve, where you can use clean washrooms and stock up on snacks.
Carry
- Touchscreen gloves
- Power bank (cold drains battery fast)
- A thermos with warm tea
- Extra wool socks
- A small daypack
Final Thoughts
Standing in front of a billion-year-old frozen waterfall, surrounded by untouched snow and absolute silence, was a moment of pure gratitude for me.
This trek wasn’t just another item on my Finland itinerary—it was a reminder of why I love the mountains, why I chase new experiences, and why nature never stops surprising us.
If you’re planning a winter trip to Rovaniemi, make sure Korouoma Canyon finds a place in your bucket list. It’s raw, it’s magical, and it will stay with you long after your footprints in the snow disappear.
