An island that began as a palace

The Mountain Resort was founded in 1703 and grew over 89 years under the Kangxi, Yongzheng and Qianlong emperors into the largest surviving imperial garden in the world. Its lake zone is a patchwork of ponds and islands joined by bridges and dykes, and Ruyi Island sits at the centre of that waterland, just north of the Moonlight-on-the-River islet. In the resort's first years, before the formal palace precinct (the Zhengong) was finished around 1711, Ruyi Island itself was the palace—where the emperor lodged, received officials and escaped the summer heat of Beijing.↗↗

That origin shows in the architecture. The buildings on the island survive in unusually complete form, arranged in a deft, close-woven plan. Long corridors and short garden walls slice the ground into a sequence of smaller courts, blending the enclosure of a northern courtyard house with the open, water-loving gestures of southern gardens—an elegant summary of how this northern imperial resort borrowed the best of Jiangnan design.↗

The scenes worth pausing for

Ruyi Island's gate hall, Wushu Qingliang ("Cool Without Summer"), is the place to start. Built in 1704 and the third of the Kangxi Emperor's Thirty-six Scenes, its wide, screen-less halls open to water on every side, engineered for breezes: Kangxi himself inscribed the plaque and praised the site as a place where cool winds arrive even in the deepest heat of high summer. Behind it stand Yanxun Shanguan, the fourth of his scenes, and the terrace buildings of Shuifang Yanxiu—together the island's architectural core.↗↗

Keep wandering to find the lotus-viewing pavilions, the Golden Lotus in the Sun and the quiet courtyard of Yipian Yun ("A Drift of Cloud"). To the west, the little islet of Canglang Yu recreates the mood of Suzhou's famous Wave-Washing Pavilion, while the Borexiang hall and the stone drums and gate of Falin Temple add a monastic touch and one of Qianlong's own named scenes.↗↗

Step off the island's north shore and you face Qinglian Island and its Misty Rain Tower (Yanyu Lou), a twin-roofed pavilion modelled on the one over the lake at Jiaxing—easily the most photographed view on any stroll through this part of the gardens, and a fine reason to approach Ruyi Island by water and bridges rather than rushing past.

Making the visit work

Ruyi Island sits inside the Mountain Resort ticketed area, reached on foot by following the lake-zone route from the palace quarter across the causeways and jetties—the resort's own north, central and west walking routes all "land on Ruyi Island" and tick off Golden Lotus, Cool Without Summer, Yanxun Shanguan, Shuifang Yanxiu and A Drift of Cloud in a logical loop. Give yourself a relaxed hour or two here; the whole resort is enormous, so it rewards picking one lake district and lingering rather than trying to see everything.↗

Timing is everything in a garden literally named for escaping the heat. The best season is late summer into early autumn, when the lotus, the open pavilions and the cooling water views all do their intended work. The resort keeps long hours through the warm months (roughly 7:00 to 18:00 from May to early October, with ticket sales stopping about half an hour before closing), easing to shorter winter hours; note that the hill district can be closed for fire prevention in the dry spring and winter, but the lake zone and Ruyi Island stay accessible.↗↗

As part of the UNESCO-listed Mountain Resort and its Outlying Temples, Ruyi Island pairs naturally with a morning here and an afternoon at the great lamaseries on the hills to the north—especially the Puning and Putuo Zongcheng temples—to read the resort's gardens and its frontier politics together.
