Mountains tend to have streams flowing down and these streams tend to have cascades. It would be impossible to list them all. Some have popular public parks, other places are more private. They do provide some of the areas most pleasant places to visit.
Huai Mae Sai Falls - take Rt. 1207 to Ban Thung Luang, go west on a dirt road past Ban Huai Mae Sai (a Yao village), then an U Lo Akha village and finally a Lahu village where you must avoid a left turn and cross a small bridge, the further side of which is rough road. There are 2 levels; the second being a much higher falls. Trees are marked with their names in Thai, there's a stone pathway and a dirt one just a bit higher up, along which small horses are often led. There are trash receptacles, and there's sand by the pools.
Poang Prabaht - west off Hwy 1 by Ban Kuk (just north of the airport road at kilo 835), past the hot springs (at the right turning) and to the very end of the road. The falls aren't high, but the landscaping is quite lovely, and it's easily accessible. West from Hwy 1 at K835 to road's end.
Nang Lae Nai W.F. - past of Wat Nang Lae, west across the highway from Mae Fah Luang Univ., in Khao Doi Yao, north of Poang Prabat.
Khun Gon - about 15 km west of town bear right on 1208, follow to the end of paved road (maybe 10 km more). Walk 2k. The 70-meter fall (highest in the province!) produces an incredible spray! There's a small waterside park a few kilometers below the final car park, and a 2.3-kilometer circular trail. Well cared for, with bamboo bridges and benches, there's restrooms by the parking area.

Huai Kaeo - beyond Pong Nam Ron hot springs and Akha Hill Guest House, due west of town. The pavement leaves off somewhere past the hot springs, toward the guesthouse, but it's hardly a long or difficult journey.
Pu Kaeng - west from Hwy 1 close to the Phayao border, turn at Ban Pukaeng, south of Phan. The largest waterfall in Chiang Rai, with strong current all year round. In Doi Luang National Park.
Huai Nam Un - 30 km north of Mae Suai, west past some beautifully terraced fields in a sizeable valley. Due to stream crossings, a 4-wheel drive vehicle or mountain bike is advisable. There is a pleasantly shaded pool beneath the fall.
Huai Mae Yao - Rt. 1207 to Ban Huai Khom (Karen) and Mountain View Guest House brings one to 3 km of dirt road and a kilometer long trail. U Lo Akha and Lahu live in the area.
Khun Jae - at the southern end of the province, about 12 Km off Rt 118 (west of Mae Kajaan in a national park).

Lalichi and Huay Mae Kam - at the tip of the northwestern peninsula of the province sticking into Burma - long not readily accessible, there's a new hard-top ceiled road now - a mountainous 100 km drive from Chiang Rai City. Tribal area.
Suan Tai and Mang Gara - west of Ban Wawi and the Moang River, both of these falls are only a few kilos from a Yunnanese village, Ban Lee Wu. The area has only dirt trails, and a local guide is very advisable.
Huai Kaang Pla - south of 1089 at km75 and almost 4 km south (cross the Mae Jan river to Ban Phattana then go past the Lahu and Akha Ban Huai Kaang Pla, and on to a dirt track).
Huai Champu - first get to Ban Mae Salak at the Chiang Mai border on the Kok River (4 km south of Ban Tha Mae Kaeng, Rt 1089), then go 6 km south on dirt roads.
Paang Sa - south of the Mae Jan River, west of Mae Chan; cross the river south from 1089 between km66 and 67, and pass Ban Paang Sa (Lisu).

Pattana - 8 km on dirt road from Ban Lao on 1173, not far from the 'Buddha's footprint' by Ban Pa Ha (north from k21, at the south end of Doi Kew Yao).
Taad Tam - 1 km trail after 7.3 km dirt road from Mae Tam on 1174 (k95). 6 m further in is Taad Khuan Waaterfall.
Huai Tong, Huay Mong and Muang Gaan - due west from Chiang Khong south of 1129 near Wiang Pha Taek. Find a local guide!
Poang Salam - southwest of Huai Nam Un, well west of Karen Guest House - a 3-hour walk!
Pha Lae - off 1155, west from Ban Sai Thong (Hmong), 9 km of dirt road. Very tall.
Taad Mok - off Rt 1020 at kilo 95 (just south of Rt 1174), just a couple kilos of dirt road.
Khoon PaDaeng and Shompoo - both near Tad Mok, between 1020 & 1155 north of Khoon Dtaan, east of Phaya Mengrai

Huay Ta W.F. - by Doi Pong, south of Khoon Dtaan (east of Phraya Mengrai), just south of Khoon Dtarn.
Taad Tong W.F. - near Suan Doi Ob south of Mae Jaan and the Chan River
Huai Meng - 6 km west from Ban Huai Meng (Tai Lue), which is on 1120 north of Chiang Khong.
Wang Pha Taek - 1129 in Chiang Rai's northeastern hump goes almost east-west awhile. South of this 2.5 km, mostly on trail.

Ban Rai W.F. - east of Mae Aeb near Doi Luang Prae Muang
Mai Aeb - south from 1129 east of Chiang Saen, turn just past Ban Sobkok toward Ban Pa Tung and follow 4 km of dirt road. Yao, Yunnanese, KMT and Hmong area.

Taad Sai Rung W.F. - 3 km east of Ban Pa Sa off Rt 1173, not far from Chiang Rung and the Waterford Valley Golf Club. It was completely dry March 1, 2001, but that was unusual.
One not in other guides is about 1.5 kilos through rice-fields past a Lisu village accessible from the market at Rt 1089 and 1209 intersection. One passes two failed housing construction projects, one with a wood gate...
Along the eastern border are also Huay Miang W.F. and Phamog Waterfalls... Others include Saeng Dao, Huai Sai Thong, Huai Dong, Huai Dai and Dad Fon.
