An In-Depth Look at the Tour Experience

Starting Point and Transportation

The tour kicks off with a private transfer from Nagano Station or your preferred location, making the experience convenient and comfortable. Compared to public transport—which often involves multiple transfers and long waits—this setup saves time and energy, especially after a long flight or train ride. The guide is an English speaker, ensuring smooth communication and insightful commentary along the way.

The Hidden Emerald Lake in Shiga Kogen

The highlight of this trip is the morning hike to a secret alpine lake in the UNESCO Biosphere Reserve. This isn’t a place you’ll find crowded with selfie sticks—it’s a peaceful spot known mainly to locals. The lake’s emerald hue is captivating, thanks to the mineral-rich waters and the high-altitude environment. We loved the way the landscape transitions with the seasons—spring flowers, summer greens, autumn leaves, or even snow in winter—each offering unique photo opportunities.

The walk to the lake is suitable for all fitness levels, with a gentle trail that rewards you with stunning views and a sense of untouched wilderness. As one reviewer noted, the landscape was “absolutely breathtaking,” providing a serene retreat from busy tourist spots.

Wildlife Spotting Opportunities

This area’s biodiversity is impressive. Keep an eye out for playful macaques, often seen near the forests, or the elusive Japanese serow—a goat-antelope that blends seamlessly into the rocky slopes. Occasionally, you might spot a stoat darting through the undergrowth, adding a dash of excitement for nature lovers. The guide’s local knowledge enhances the experience, helping you understand the ecosystem and increasing your chances of wildlife sightings.
