- Mount Aso (Nakadake crater): The active crater is the park’s headline act — steaming fumaroles, a stark lunar-like crater floor and up-close reminders that this place is alive. You can often walk to viewing platforms (access varies with activity), so check warnings before you go.
- Aso Caldera and its rim (Daikanbo viewpoint): One of the world’s largest calderas — think a huge green bowl with volcanic peaks popping out. Daikanbo gives the classic wide-angle view at sunrise or late afternoon; great for photos and for getting your bearings across the whole park.
- Kusasenri grassland: A flat, breezy expanse inside the caldera where horses graze and you can wander easy paths. It’s peaceful, photogenic and simple to combine with a short climb up the cone-shaped Komezuka next door for a different

- Komezuka volcanic cone: A short, steep climb to a perfectly shaped little cone — takes 15-30 minutes but the 360° views back over Kusasenri and the caldera are worth it. Nice quick hike when you want payoff without a long trek.
- Kuju Mountain Range and ridgeline hikes: Swap the caldera for the high, windswept Kuju peaks — long ridges, panoramic summits and seasonal bloom carpets (spring/summer). Trails range from day-hikes to longer ridge walks; it’s proper mountain country with great sunrise potential.
- Kuju flower meadows / flower parks: In summer the plateaus burst with mountain flowers — gentians, lilies and spring azaleas earlier in the year. Good timing = spectacular color; bad timing = still lovely open moorland and cooler temperatures than the lowlands.
- Aso Volcano Museum: Short, hands-on exhibits that explain how the caldera formed and what’s happening under your feet. Useful before you hike if you want the geology without reading a thesis — also has practical safety info about eruptions.
