Once one of the major cities of the Lanna kingdom, it was originally called Wiang Hiran Nakhon Ngoen Yang and served as the capital before King Mengrai established Chiang Rai in 1262. The town was captured by the Burmese in the 16th century and sacked by King Rama I in 1803. Left a ghost town for a hundred years, it was repopulated around 1900, but still hasn't really staggered to its feet. Traces of old double city walls and many other antiquities still remain in and outside the town.
Chiang Saen is connected by local bus to Chiang Rai (2-2.5 hrs, nominally. 3-4 per hour but tend to depart when reasonably full, 37 baht). There are a few, 3-4 per day, long-distance buses which can do the trip in 1.5 hrs, but times are more convenient for long-distance journeys such as going to or from Chiang Mai or Bangkok than for commuting to Chang Rai. Blue songthaews also travel from Mae Sai via the Golden Triangle to Chiang Saen in about 1 hour. The timetable for this service is chalked up at the depot which is next to the bus stop. These seem to depart every half hour or so. The service from the Golden Triangle to Chiang Saen seems to be much more irregular. The service varies with customers available and the flow of life along the Mekong and the Myanmar border.
The bus station and songthaew depot is about 50 m before the main road (Hwy 1016) ends in a T-intersection on the banks of the Mekong River.
There does not appear to be any regular public transport south to Chiang Khong and the Lao border crossing, apart from the occasional songthaew. Ask locally for details of this service as departures times vary.
The district can be reached by taking Hwy 110 from Chiang Rai for some 30 km. Then take a right turn onto Hwy 1016 and proceed on for another 30 km.
Like Chiang Mai, Chiang Saen has a city wall surrounding the historic town, with the fourth "wall" provided by the Mekong River.

These items include musical instruments, ornaments, opium-smoking accessories.
- Wat Pa Sak (วัดป่าสัก) (About 1 km to the W of Chiang Saen in Wiang). Built by King Saen Phu in 1295 when three hundred teak trees were planted, hence the name Pa Sak (teak wood). It was then the residence of the patriarch. The temple's chedi is beautiful in Chiang Saen-style and the exteriors are elaborately decorated with designs. The chedi itself measures 12.5 m tall with a base of 8 m width, enshrined with the Lord Buddha's relics.

A 1,200 kg Buddha statue was cast, 2 m wide and over 3 m high, named Phra Chao Lan Thong. Another Buddha statue called Phra Chao Thong Thip was also cast which is made of brass in Sukhothai-style.
- Wat Phra That Chedi Luang (วัดพระธาตุเจดีย์หลวง) (In Chiang Saen old town). Built by King Saen Phu, the 3rd ruler of the Lanna kingdom in the early 13th century.

There are also remains of ancient viharn and chedi.
- Wat Phra That Pha Ngao (วัดพระธาตุผาเงา) (About 4 km from Chiang Saen on the road to Chiang Khong). There is a bell-shaped chedi standing on large boulders. Nearby is a viharn where several old Chiang Saen-style Buddha statues are enshrined. There is also a viewpoint overlooking the Mekong and Chiang Saen. The temple attracts many Thai visitors. Part of the temple was found to be at least 700-1,300 years old. The temple has welcomed the royal family on many occasions over the last few decades.
There are also several ancient sites outside the city wall including Wat Phra That Pha Ngao (วัดพระธาตุผาเงา), a place for dharma practice. Wat Chedi Ched Tod (วัดเจดีย์เจ็ดยอด) is a peaceful place, 1 km beyond Wat Phra That Pha Ngao. Wat Phra That Chom Kitti (วัดพระธาตุจอมกิตติ), about 1.7 km from town, and Wat Sangkha Kaeo Don Han (วัดสังฆาแก้วดอนหัน) where sketches on brick slabs tell stories about the life of the Lord Buddha.
- Songkran Festival and Boat Races (งานประเพณีสงกรานต์และแข่งเรือเมืองเชียงแสน). Held 13-18 Apr every year. In this festival, there is a parade featuring the water bathing ceremony of the Phrachao Lanthong Buddha image. There are also boat races and folk performances.
- Loi Krathong Festival The festival day usually falls in the month of November depending on the Thai lunar calendar.
In the evening, many local food stalls set up shop along the bank of the Mekong north of the T-junction. The tables set are small, and you sit on a mat on the ground as locals do. Menu in English and Thai. Try the bamboo chicken and/or bamboo fish (cooked inside bamboo on charcoal fires).
If you walk north beyond the night market, to where the road turns away from the river, there are several eateries sharing a covered terrace above the river. Parking is available. These provide a cafe/basic restaurant setting. The food available at all these outlets is excellent value with a similar but not identical set of standard dishes to choose from at each outlet. The quality is more than adequate, more basic good value rather than exquisite, but the dishes are well-prepared, cooked to order, and taste authentic. The service is pleasant and the beer is cold. The cooks take pride in their work
There is a small restaurant opposite the new banking establishments halfway down the main drag (on your left as you face the river). The food is perfectly adequate and one will not be disappointed. The value is good and the beer is cold. The service is good and the owners are trying hard.
Accommodations in Chiang Saen are limited. Fancier digs are to be found in the Golden Triangle, just north of Chiang Saen.
- Chiang Saen Guesthouse (From the T-intersection along the river, walk 5-10 minutes north along the road).
- Chiang Saen River Hill Hotel. A mid-range option. The rooms are well furnished, of reasonable size and the staff are both friendly and helpful. The hotel flows with the passing of tour groups. Should a large tour group turn up while you are there, you could feel neglected as the staff struggle to cope. A very noisy karaoke party might keep you awake if your room is immediately over the restaurant/bar area, but the hotel tries to wind these down by 22:00. Sadly hotels like these must accommodate the tour groups idea of a good time so some bad reviews might just reflect a bad tour group. Left to its own devices this hotel is an excellent and good value mid-range option. Wi-Fi is available in the lobby area. 900 baht.
