Rovaniemi: Sukulanrakka & Devil’s Churns Tour

Glacier water carved holes in seconds. This Sukulanrakka outing turns a short drive from Rovaniemi into a guided walk where you’ll see devil’s churns, 14 potholes shaped by meltwater after the last ice age.

I especially love the sheer scale, from the 8 meters wide and 15 meters deep giant to two more major potholes with depths of 9 and 10 meters. I also like how the guide ties what you see to the process, from glacier meltwater rushing through tunnels to swirling eddies drilling into rock.

One consideration: the route includes hiking on uneven terrain, so it’s not a great fit if you have mobility limits or if you’re afraid of heights.

Key things I’d bookmark before you go

• Sukulanrakka is only 25 km from Rovaniemi, so you can do this without a long day on the road
• 14 devil’s churns to spot, including three of Finland’s largest potholes
• The main giant is 8 meters in diameter and 15 meters deep, plus two others at 9 and 10 meters deep
• A live English guide with a small group, limited to 8 participants
• About 1.5 hours of walking, so comfortable shoes matter

Why Sukulanrakka feels like instant geology

Lapland is famous for big skies and wide open tundra, but this tour gives you something more tactile: rock that was carved, not just weathered. Sukulanrakka sits about 25 km from Rovaniemi, close enough that you can fit it into your plans without spending the whole day commuting.

What makes it genuinely interesting is that the potholes are not random. The formations were created around 10,000 years ago as the continental ice sheet melted and torrents of meltwater rushed through underground tunnels. When you’re standing near those depressions, the story stops being abstract and becomes visible, like the landscape is showing you the steps of a process.

I also like the pacing. You’re not speeding past viewpoints. You get a guided walk and time to look closely, and the guide’s explanations help you connect the size, shape, and placement of the potholes to the water flow that formed them.

Getting to the devil’s churns, and what the walk is really like

This is a 2.5-hour experience with pickup in Rovaniemi and a return transfer back to the city. The active part is about 1.5 hours of walking and hiking, which you should treat as your main time commitment.

The terrain can be challenging, so it helps to plan for real outdoor walking, not a flat stroll. You’ll want shoes with grip, because you’re dealing with natural ground conditions and paths in Lapland. If you’re planning on snapping photos, also remember that you may be stopping, turning, and stepping carefully for better angles.

A small group matters here. Limited to 8 participants, you’ll usually have an easier time hearing the guide and seeing what they point out, without feeling like you’re in a long line. And since the guide is live and in English, you’re not forced to guess what you’re looking at.

One practical note: drones aren’t allowed. Bring a camera, but plan to shoot from ground level and let the guide direct you to the best spots.

The 14 potholes: spotting the biggest ones without missing the story

The star of the show is Sukulanrakka’s set of 14 devil’s churns, unique potholes carved by nature. You’ll spend your time looking for key formations, but the value is not just counting holes. The guide frames them so you understand why some are larger and why they look the way they do.

Here’s what you can look forward to seeing:

• The largest pothole: 8 meters in diameter and 15 meters deep. This is the one your eye will keep returning to, because it’s massive in scale compared to the rest.
• Two other major potholes: one 9 meters deep and another 10 meters deep. These sit on rocky slopes and feel imposing, partly because of how much depth the guide helps you visualize.

When you’re standing near a deep pothole, it can look deceptively simple from a distance. Up close, you start noticing details like how the rock is cleared and shaped around the depression. That’s where the guide’s explanation makes a difference: the devil’s churns aren’t just holes, they’re evidence of erosion driven by high-energy water flow.

If you’re hoping for dramatic photo moments, arrive mentally prepared to do some careful looking. The best shots come from taking your time, stepping to safer vantage points, and listening to what the guide tells you to focus on.

How meltwater tunnels and swirling eddies carved these holes

The tour’s biggest payoff for curious minds is the explanation of how the potholes were formed. The basic idea is pretty clear: as the ice sheet melted, meltwater surged and moved through tunnels at the base of the glacier. That rushing water eroded the rock.

But the guide goes further, and that’s what makes it satisfying. You learn that the devil’s churns were shaped by swirling eddies and boulders carried along by the flow. In other words, the action wasn’t gentle. It was turbulent, energetic, and concentrated in channels that cleared away soil and rock.

Why does that matter for you? Because it changes how you view the site. Instead of thinking, these holes just appeared, you start thinking, this is where the water’s power focused. The size and depth become clues about where the strongest currents likely ran and how long the erosion worked.

Also, keep in mind the time frame. These features formed about 10,000 years ago, which is long enough that you can’t feel it as “recent,” but close enough that the shapes are still here, readable on foot.

If you enjoy science you can actually see, this tour hits the sweet spot. It’s educational without being stuffy, and it’s specific without turning into a lecture you can’t use.

Meet your guide, and how the experience stays human

One thing I really like about this tour setup is the combination of a small group and a live guide. In a recent experience, the English-language guide was Andrei, and the overall vibe was punctual, attentive, and genuinely helpful. That matters because the potholes are not all identical, and you’ll miss details if you’re just walking and hoping to figure it out.

A good guide also helps you navigate the route at a comfortable pace. The hike is short, but the terrain can be tricky, and knowing where to step helps you stay focused on the geology instead of your footing.

Since the tour is run by Helios Tour, you can also expect a consistent approach: guided viewing of Sukulanrakka’s devil’s churns, plus transfers that reduce hassle. It’s the kind of day that feels organized, even when the landscape is wild and uneven.

What to bring for Sukulanrakka (and what can ruin your day)

This is an outdoor walking tour, so your prep matters more than you might think. You’ll be out in Lapland conditions, and you’ll feel it if you’re underdressed or unprepared.

Bring:

• Comfortable shoes for hiking and uneven ground
• Outdoor clothing suited to the weather
• Water and snacks, since meals and drinks aren’t included
• A camera, for those dramatic pothole moments

Also, pack with timing in mind. The full tour is 2.5 hours, so you want to have what you need without wasting time later. Since you’re walking about 1.5 hours, dehydration or hunger can sneak up on you.

Don’t bring:

• Anything related to smoking, since smoking isn’t allowed
• Drones, since they’re not allowed

One more practical tip: if you know you’ll want photos, plan to move slowly at key stops. Trying to rush through while also stepping around rocky areas often leads to blurry shots and missed explanations.

Price and value: is $106 worth your time?

At about $106 per person for a 2.5-hour guided experience, you’re paying for three things: the specialist guiding, the short hike time, and the transfer between Rovaniemi and the site. You’re also paying for a small group size, limited to 8 participants, which helps you get real attention instead of crowd management.

If you’re the type of traveler who likes learning while walking, the value is solid. You get to see the largest pothole in the lineup plus two other big ones, and you get a clear explanation of how the devil’s churns formed from meltwater action and erosion. It’s not just sightseeing. It’s a guided science experience you can actually stand inside the story of.

If you’re only looking for casual views and you dislike walking, then the price may feel steep for what is essentially a short hike on challenging terrain. In that case, you might prefer a lighter outing.

Who should book, and who should skip this one

This tour is best for people who enjoy short hikes and hands-on learning. If you want to see real geological formations up close, and you’re comfortable walking for about 1.5 hours, you’ll likely enjoy it a lot.

It’s not a great match if you:

• Are under 6 years old
• Have mobility impairments
• Are very young and not ready for uneven terrain
• Are afraid of heights, since some of the potholes are viewed from rocky slopes

If you’re traveling with kids, double-check their comfort with outdoor walking and uneven ground. The tour is meant for those who can focus on both safety and scenery.

Final call: should you book the Sukulanrakka devil’s churns tour?

I’d book it if you want a short, guided Lapland experience that mixes real visuals with a clear explanation of how they were formed. The standout reason is the scale and specificity: 14 devil’s churns, including the 8-meter-wide, 15-meter-deep giant, plus the 9 and 10-meter depth potholes. Add a small group and an English guide, and you get a focused outing that feels worth the price.

Skip it if hiking on challenging terrain sounds stressful, or if heights make you uneasy. Also, if you hate outdoor weather planning, you’ll feel it here, since meals aren’t included and you’ll want water and snacks.

If you’re ready for an outdoorsy, geology-rich half-day and you like getting your facts straight, Sukulanrakka is an easy yes.
