A national park in Hokkaidō featuring volcanoes, forests, and three spectacular lakes: Akan, Mashū, and Kussharo. Lake Mashū is one of the clearest lakes in the world.

📋 Practical info
Getting there
The national park is easily accessed by rental car or regional buses from Kushiro or Memanbetsu airports. Driving is typically the most convenient way to explore the vast distances between the three lakes.
Best season
Summer provides pleasant hiking conditions, lush green forests, and typically clear views of the volcanic caldera lakes. Winter transforms the area into a striking snowscape, though some higher roads may close.
Terrain & paths
The diverse landscape ranges from flat, paved lakeside promenades at Lake Akan to rugged, unpaved volcanic trails. Hiking paths to the surrounding peaks demand moderate fitness and sturdy footwear.
What to bring
Sturdy hiking boots and weather-appropriate outdoor layers are essential for venturing beyond the immediate lakeside areas. Consider bringing binoculars to spot wildlife like red-crowned cranes or deer.
Parking
Ample and convenient parking is generally available at the main volcanic viewpoints, official visitor centers, and hot spring resorts. Some of the major observation decks may charge a small parking fee.
Safety
Always check the latest local weather forecasts and volcanic activity reports before setting out on high trails. Be aware of your surroundings as brown bears inhabit the denser forested areas of Hokkaido.
Time needed
A typical visit ranges from a single full day of driving between viewpoints to three days of extensive exploration. Multi-day stays are good for combining challenging hikes with relaxing hot spring baths.
