Shanwangping Karst National Eco-Park is one of Nanchuan’s quieter wonders, famous for a forest that splits into two colours on two facing slopes. One hillside glows gold while the other stays deep green, a trick of two different tree species growing side by side. Add stone-forest karst, eco-bridges and a curved mountain road, and you have a landscape built for slow looking.

The two colours come from water-fir on one side and cryptomeria on the other, planted so close that the line between them is sharp in autumn. When the firs turn, the contrast is striking enough that people drive in from Chongqing just to see it. The air is clean and the paths are gentle, so the park suits a relaxed walk more than a hard hike.

Beyond the trees, the park is real karst country. Stone-forest formations rise from the grass, and eco-bridges let visitors cross small ravines without disturbing the ground below. The S-bend road is the other draw, a sweeping curve that photographers wait for at dawn and dusk when the light rakes across the slopes.

Shanwangping is a place to take your time. Most visitors arrive for the autumn colour, but the green slope alone is worth the trip in other months, and the stone forest is quiet year-round. Plan a half-day, bring a camera, and walk the loop rather than rushing the viewpoint, because the best frames are found between the marked stops.
Words and Names
- Shanwangping Karst National Eco-Park (山王坪喀斯特国家生态公园) — the twin-colour forest park in Nanchuan.
- Water-fir (水杉) — the tree whose autumn gold gives one slope its colour.
- Cryptomeria (柳杉) — the evergreen tree that keeps the facing slope green.
- Stone forest (石林) — the karst rock pillars scattered through the park.
- S-bend road (S湾公路) — the curved mountain road photographers come for.
What the Locals Know
The colour split is at its peak in mid to late autumn, when the water-firs turn and the line between gold and green is sharpest; locals say a clear dry day shows it best. The S-bend road is most photogenic at first light or just before sunset, when shadows lengthen across the curve. Weekends in autumn get busy, so a weekday visit means easier parking and cleaner shots.
Wear sturdy shoes, because the grass and stone areas can be uneven and damp in the morning. The park sits higher and cooler than the seat, so bring a layer even in autumn. Pack water and a snack, since services inside are limited, and give yourself the full loop rather than only the road viewpoint.
The listed ticket is 58 yuan, which covers the park entry; the draw is the landscape itself, so no extra paid sights are needed to enjoy it. Arrive early if you want the road empty for photos.
