Annupuri Mountain: Summer Hiking and Views Above the Niseko Valley

Why Annupuri Mountain Is Worth Hiking in Summer

Annupuri Mountain (ニセコアンヌプリ) is best known internationally as a ski destination — the 1,308m peak at the heart of the Niseko United resort cluster that attracts powder enthusiasts from across the world. In summer, the same mountain offers something quieter and more accessible: a half-day hike to a summit with a panoramic view of the Niseko valley and, on clear days, the unmistakable volcanic cone of Mt Yotei rising across the lowlands to the southeast.

For visitors staying in the Niseko area, Annupuri is among the most convenient Hokkaido mountain destinations to incorporate into a summer trip. The trailhead is in Goshiki Onsen village, reached by car or bus from Niseko accommodation, and the hike is achievable in a half day — leaving the afternoon for the hot spring recovery that the trail's starting point conveniently provides. Annupuri is not the most dramatic or remote Hokkaido peak, but it is a genuinely rewarding hike with real summit views and minimal technical difficulty.

The mountain sits within the broader Niseko area landscape, where volcanic terrain creates a rolling skyline framed by farms and forests. Niseko's elevation profile gives some context for why the area receives such exceptional snow in winter; in summer, that same topography makes for green, flower-dotted hillsides below and open ridge above.

The Route: Goshiki Onsen Trailhead to the Summit

The standard approach to Annupuri's summit starts at Goshiki Onsen (五色温泉, Goshiki Onsen — literally "five-color hot spring," named for the shifting hue of its mineral-rich waters). The onsen sits approximately 10 kilometres from the Niseko Annupuri Village base area and serves as both the hiking trailhead and the post-hike recovery destination.

According to the Niseko Tourism Association, the hike from the Goshiki Onsen trailhead to the summit takes approximately 1.5 to 2 hours. The trail ascends steadily through forest before breaking out into open rocky terrain on the upper section. The elevation gain is moderate — Goshiki Onsen sits at around 750m, and the summit is at 1,308m, making for roughly 550m of vertical gain. The descent is slightly faster, typically 1 to 1.5 hours.

The trail surface changes character above the treeline. The lower section is forested and well-maintained; the upper section involves loose and sometimes steep rocky terrain that requires proper ankle-support hiking boots. Trail runners are less appropriate here than they are on some smoother mountain paths. Community reports consistently note rocky terrain as the element that catches hikers off guard — plan your footwear accordingly.

Bring bug spray. Summer mosquitoes in Hokkaido's forests are persistent, and the lower forested section of the Annupuri trail sees enough moisture to support them. Once above the treeline, insects are less of an issue, but the first 30-40 minutes of the hike pass through forest where spray makes a genuine difference.

The total round-trip time from Goshiki Onsen — hiking both ways — is typically 3 to 4 hours including rest stops. An early start (8:00-9:00 AM) puts you on the summit before midday cloud builds, which is the pattern on many summer days in the Niseko area.

What You See from the Top: Mt Yotei and the Niseko Panorama

The summit view's centerpiece, on clear days, is Mt Yotei (羊蹄山). Yotei's nearly perfect volcanic cone rises to 1,898m to the southeast of Annupuri, across the broad valley floor of the Niseko lowlands. From Annupuri's summit, you're looking at the mountain from roughly the same elevation as Yotei's lower slopes — the full cone profile is visible above the valley in a way that confirms why the mountain earned the nickname Ezo Fuji. The view from Annupuri's summit is one of the cleaner viewing angles of Yotei's silhouette in the Niseko area.

For a deeper exploration of Yotei's mountain character and hiking routes, see our Mount Yotei hiking guide. If photographing Yotei's silhouette from multiple vantage points is your priority, the best Yotei views across the Niseko landscape guide covers the full range of viewing locations.

Beyond Yotei, the summit panorama extends across the rolling terrain of the Niseko Volcanic Group — the cluster of peaks that includes Annupuri, Niseko-Moiwa, and Higashiyama. On particularly clear days, the landscape opens toward the surrounding lowlands with farmland and forested hills stretching toward the horizon. The view is not as dramatic as a high alpine summit would be — Annupuri's 1,308m keeps it below the cloud-piercing elevations of Hokkaido's biggest peaks — but the combination of Yotei's cone, the Niseko valley, and the open ridge is considerably more rewarding than the elevation suggests.

July through September offers the most reliably clear summit conditions. Morning hours before noon tend to have better visibility than afternoons, when cloud can build over the valley.

The Summer Gondola: Fares, Season, and When to Use It

According to the official Niseko Annupuri site, a summer gondola (ゴンドラ) operates on Annupuri from early June through early October. The gondola runs 9:00 to 16:00 and carries visitors from the base to a higher elevation starting point, reducing the total elevation gain required to reach the summit. The adult round-trip fare was ¥2,500 (~$17) as of 2025 data. Verify current fares and operating dates on the official Niseko Annupuri website before your visit, as dates vary year to year.

The gondola is the same lift infrastructure that operates in winter for Annupuri's ski terrain, repurposed for summer sightseeing and hiking access. Using the gondola one way makes the most sense for hikers who want to reduce the total effort: hike up from Goshiki Onsen in the morning (when it's cooler and clearer), then ride the gondola down to save your legs for the rest of the day. Alternatively, take the gondola up and hike down — the downhill on Annupuri's rocky upper section is where trekking poles earn their keep.

If the gondola is not operating on the day you visit (weather closures are possible), the full hike from Goshiki Onsen remains the primary access and is how most hikers approach the summit.

After the Hike: Goshiki Onsen and Getting There from Niseko

Goshiki Onsen (五色温泉) at the trailhead is not just the starting point — it's one of the most natural post-hike endings available on any Hokkaido mountain. The hot spring baths open from 10:00 to 21:00, with adult entry at ¥800 (~$6). The mineral-rich water comes from the same volcanic system that shaped the Niseko Volcanic Group, producing the sulfurous, slightly opaque water typical of Hokkaido's volcanic hot springs. After 3-4 hours of hiking on rocky terrain, the combination of hot water and the mountain backdrop makes for a satisfying end to the day.

To reach Goshiki Onsen from Niseko accommodation:

• By car: The onsen is approximately 10 kilometres from the Niseko Annupuri Village base area. A free parking lot is available at the trailhead. From Sapporo, take the Hokkaido Expressway toward Niseko and then drive approximately 20 minutes to Goshiki Onsen.
• By bus: A bus runs from the Hirafu area to Goshiki Onsen, taking approximately 30 minutes. Check the Niseko Tourism Association for current summer bus schedules, as frequency varies by season.

No advance registration or permit is required to hike Annupuri. The trail is open to self-guided hikers throughout the June-to-early November season.

Frequently Asked Questions

How long does it take to hike Annupuri from Goshiki Onsen to the summit?

According to the Niseko Tourism Association, the ascent from the Goshiki Onsen trailhead to the summit takes approximately 1.5 to 2 hours. The descent is slightly faster, typically 1 to 1.5 hours. The full round trip without the gondola runs 3 to 4 hours including rest stops. Using the summer gondola for one direction reduces the total time and effort significantly.

Does the summer gondola operate on Annupuri, and what does it cost?

Yes — the Niseko Annupuri summer gondola operates from early June through early October, running 9:00 to 16:00. The adult round-trip fare was ¥2,500 (~$17) as of 2025 sources. The gondola takes you to a higher elevation starting point, reducing the total elevation gain to the summit. Check the official Niseko Annupuri website for current fares and operating dates, as the schedule varies by year. No reservation is required.

Is Annupuri suitable for families or less experienced hikers?

Yes — Annupuri is one of the more accessible Hokkaido summits for non-specialist hikers. The trail is not technically demanding, but the upper section involves rocky terrain that requires proper ankle-support hiking boots rather than casual footwear. The 1.5 to 2 hour ascent is manageable for fit adults and older children. The summer gondola option further reduces the commitment for those who want to limit the hiking time.

What is the best season to hike Annupuri?

The hiking season runs June through early November, with snow-free trails typically available from late June. July through September offers the best combination of clear summit views, comfortable temperatures, and reliable access. Avoid late May — the upper sections retain significant snow and conditions are unpredictable. The gondola also operates from early June, making late June and July the practical start of the full season.

Can you see Mt Yotei (Ezo Fuji) from the Annupuri summit?

Yes — on clear days, Mt Yotei's volcanic cone is the dominant feature of the view from Annupuri's summit. It rises to the southeast across the Niseko valley floor, and the full profile is clearly visible from the ridge. Morning hours before noon offer the most reliably clear conditions. Cloud tends to build over the valley in the afternoon, which can partially or fully obscure Yotei depending on conditions. July through September provides the best average visibility.
