Your full-day trip begins with transport from your Sapporo hotel to western Hokkaido, where Mount Tarumae towers above the shores of Lake Shikotsu. This 1.2-mile (2-km) hike on the active volcano offers stunning views of the lake below, as well as the rare chance to see a lava dome.

Before embarking on your 4-hour guided hike on the mountain, stop at a convenience store to purchase lunch to take along with you. You can leave any extra clothing or equipment in the van. From the restroom facilities at the trailhead, your guide takes your small group along a mountain trail. You immediately gain altitude, but your provided walking poles and a series of wooden steps should make the approximate 10-minute ascent easier. Once you reach a small clearing, admire your surroundings: gorgeous Lake Shikotsu, a steeply rising Mt Fuppishi, and the conical peak of Mt Tarumae.

From here, the well-maintained trail cuts across the eastern edge of the volcano for another 30 minutes. En route, your guide points out flora such as azaleas and Japanese snow flowers in bloom. Upon arrival at the peak, soak up spectacular views of the lake and the formidable Mt Yotei (Hokkaido Fuji) as you enjoy an hour for lunch around midday.

Perhaps the most impressive view is the smoldering lava dome rising from the crater’s rim. The active volcano is under constant surveillance by the Japan Meteorological Agency, and your expert guide knows what to do in the unlikely event of an eruption.

Once you reach the 3,353 feet (1,022 m) in elevation, begin your descent on Mt Tarumae. At the bottom, head back to the parking lot and drive to the nearby Marukoma Onsen near Lake Shikotsu. This onsen features hot springs located right at the water source, so no pipes are needed to bring the water to the pools. Only a handful of onsen restarts in Japan have this feature.

Your guide explains onsen etiquette and the features of the bathing facility such as the lockers for your belongings. Then you’re free to choose how to make the most of your time soaking those weary muscles over the course of the next hour.

Indoors, dip into the big pool or lounge in a hot bath. Or head outdoors to the rotenburu baths, which are divided by gender. Enjoy views of Lake Shikotsu as you soak. You can also relax in the common area, play in the game arcade or browse the souvenir shop.

Afterward, take a seat on the minibus as you are transported back to your hotel in Sapporo.
