2027 Riyuetan Wanrenyongdu（日月潭萬人泳渡 2027）

Maolan Shan is a mountain on the northern side of Sun Moon Lake in Yuchi Township, Nantou County, Taiwan, and is one of the southernmost mountains of the Xueshan Range. It lies roughly at the junction of Shuishe Village, Wucheng Village and Zhongming Village, is 1,016 metres above sea level, and is the highest peak of those three villages. It ranks third among the Four Beauties of Mingtan, and in 2006 was selected by the Sports Affairs Council of the Executive Yuan as one of Taiwan's Minor Hundred Peaks. The surrounding area was formerly called Maolan, from which the mountain takes its name. The summit is the site of the Sun Moon Lake Weather Station; three survey markers were originally placed there but all have been lost, and what remains are a third-order triangulation point, No. 5005, re-established by the National Land Surveying and Mapping Center, an inscribed stone reading 'Sun Moon Lake Maolan Shan', and the weather station's first-order satellite control point.

Shuishe Dashan, also called Shuishe Mountain, is a mountain southeast of Sun Moon Lake in Nantou County, Taiwan. It is one of the southernmost mountains of the Xueshan Range and one of the northernmost of the Yushan Range, located at the junction of Riyue Village and Dongguang Village in Yuchi Township and Tannan Village in Xinyi Township, and is named for its proximity on the west side to the former Shuishe area and for its massive bulk. Its highest peak is 2,103 metres above sea level, sometimes specifically called Shuishe Main Peak; on a shoulder about 550 metres to its northwest there is a second-class triangulation point No. 1134, at 2,059 metres (2,058.947 m). It is one of the hundred famous mountains of Taiwan and the first of the Four Beauties of Mingtan (the Four Siblings of Sun Moon Lake), and is the highest peak in Yuchi Township. In 2003 the mountain was selected by the Sports Affairs Council of the Executive Yuan as one of the small hundred mountains of Taiwan; in 2006 it was removed from the list because the later section of the trail was too difficult to climb.

Houjian Shan is a mountain in Nantou County, Taiwan, located to the south of Toushe Village, Yuchi Township, at a walking distance of about 3.2 kilometres and a climb of about 345 metres. Because the view from the summit is good, it is the highest point of the Toushe Basin in Yuchi Township, with direct views over the Toushe Basin and Sun Moon Lake, and local people call it 'Wanggaoliao'. Houjian Shan is also one of the Four Beauties of Sun Moon Lake (the Four Brothers and Sisters of Sun Moon Lake) and is a tourist spot for Toushe and the Sun Moon Lake area.

Toushe Reservoir is in Toushe Village (tafwale), Yuchi Township, Nantou County, Taiwan. It is formed by water from the Dashiman Stream and seepage from the Sun Moon Lake reservoir; its catchment area is 55 hectares and its effective storage capacity is about 230,000 cubic metres. The dam is an approximately homogeneous earth dam, and the reservoir belongs to the Nantou Management Office of the Irrigation Agency of the Ministry of Agriculture. Toushe Reservoir was completed in December 1979. It serves the single purpose of farmland irrigation, and is the smallest reservoir on the main island of Taiwan.
