The first thing most new visitors to Chiang Mai do is going up Doi Suthep (Mount Suthep) and visit the Buddhist temple complex. It takes about half an hour to travel up there and Doi Suthep is an obvious goal for a day tour.

If you want to do a Doi Suthep tour you can just take a taxi or songthaew up there for the afternoon; there is no need to rent a scooter. If you want to go further, to Mae Rim and the Queen Sirikit Botanical garden the best option is to rent a scooter or motorcycle and go by yourself.

Start by going up north on the 107 highway for about 20 minutes; turn left on the 1095 and follow the signs to Samoeng. You are now driving on the famous twisty Samoeng Loop.

Chiang Mai motorcycle routes to national parks.

1] The busy road to Pai.

The Samoeng loop on the other hand is a much better road which has much less traffic and many interesting things to see: there are for example great viewpoints, elephant parks, and a famous botanical garden (QSBG; see below). And there are fewer potholes as well.

And keep in mind that the road to Pai is famous for all the wrong reasons. Twisty, potholed, and it is classified as one of the most dangerous roads in Thailand. A few years ago (2016) the road was widened in some places so you can now easily overtake that slow driver; who is trying fruitlessly to go uphill on an underpowered scooter with his girlfriend on the back.

But the proper superelevation (road banking) of the curves is still missing on most curves - the road curves have almost no banking. So the cornering needs to be done with foresight and care - and experience. Unfortunately, experience is what you get - just after you need it.

Why not start your route in the morning and from Chiang Mai head north on the busy highway 107. The Dara Pirom Palace Museum in Mae Rim is worth visiting, the museum is a large historic wooden mansion which was home to the famous Lanna princess Dara Rasmi (or Rasami), who was one of the consorts of Chulalongkorn, King Rama V of Siam. And you can have a cappuccino or cake in one of the coffee shops in Mae Rim, like the artsy Wawee Coffee shop. (Update winter 2018/2019: Wawee is closed for renovation)

These hip coffee shops cater to wealthy tourists who are enjoying the posh hotels in Mae Rim and the Mae Sa valley.

There is a tribal village on the 1096 road in Mae Rim called Baan Tong Luang. It is set up for tourists, since hill tribes do not live together in one village. One of the tribes is the Longneck women tribe; these Longneck women originally come from a remote area in Burma, so it's a bit of a tourist trap. Nevertheless, if you want to see all tribes in one fell swoop then this is an opportunity. Entry fee is 500 baht.

In the Mae Sa valley there are a few elephant parks; once past these the road gets much quieter as it continues west towards Samoeng; you can drive through the beautiful valleys and mountains on a scenic twisty road dotted with villages, temples and forest.

Further on is the Queen Sirikit Botanical Garden (QSBG; www.qsbg.org) which is a famous mountainside arboretum and garden. Within the park area are gardens, glasshouses, and trails through the rainforest. The large glasshouse complex on top of the mountain is a conservatory for a wide collection of tropical plants, cacti and orchids. Since 2017 there is also a treetop walkway through the rainforest with a length of more than 400 meters. The Botanical Garden is very large and situated on a very steep mountainside, so you may want to enter by car or motorcycle; but walking up is also possible.

Once in the garden a 3,6 kilometre loop road runs around the interior. This road is on Google Streetview; as well as some of the the walking trails, like the trail through the Palm Garden. Even the inside of the main glasshouse can be visited on Streetview. There is a tram service/open air bus service that runs within the garden.

Entry fee prices for QSBG are: Adult: 100 baht; child: 50 baht; Adults with a Thai ID card: 40 baht, car (additional) 100 baht. Senior citizens (Over 60), disabled persons: FREE.

After the Samoeng Forest viewpoint you come to a T-crossing where you turn right for a 5 to 10-minute drive with just a few hairpins through the strawberry fields of the Samoeng valley; and stop at the small village of Samoeng. Here there is not much to see, but you can have a lunch break in Supanee's restaurant.

After lunch return to the T-crossing; keep on going straight and follow many twisty turns on the nr. 1269 road back to Chiang Mai. There are a few amazing downhill stretches here which are even better than the first half of the loop. And the best thing: there is very little traffic here. The full "Samoeng loop" around Doi Suthep is about 100 kilometers and takes about 3 hours on a motorcycle or scooter. The roads are in good order, the traffic is light and thus it is easy by scooter. Or motorcycle.

3] Private museums, old houses and whacky wats.

Unusual and off the grid places

Northern Thailand has many unique museums, apart from the well known official ones. Some smaller or private museums are very interesting but relatively unknown; here are a few examples.

• The MAIIAM Museum of Contemporary Art opened its doors in 2016. The Museum houses the Bunnag-Beurdeley family’s permanent collection. MAIIAM is located close to the village of San Kamphaeng, 12 km east of Chiang Mai. Just before the museum is Bo Sang, the umbrella making village with many handicraft shops, cafe's and some small eateries. Entrance fee is 150 baht; seniors 100 Baht.

• The Secret Terracotta Garden is not so secret anymore but a very beautiful and quiet walled garden in the old town. This amazing emerald green garden is just north of Chiang Mai Gate is in fact a terracotta arts studio called Baan Phor Liang Meun. The shaded garden is completely filled with clay copies of Khmer, Hindu and Thai gods. Shiva, Ganesh, Krishna, Khmer lions and many other statues from neighboring countries sit peacefully side by side. Since a few years there is a small coffee shop and restaurant; called Clay Studio Coffee (facebook.com/Clay-Studio-Coffee).
  Like many other sights in this list it is a bit hard to find because its on a small side street of Prapokklao road, to be precise on Prapok Klao Road, Soi 2. No entrance fee.

  Since 2016 they have also opened a romantic, artstic eatery/restaurant: The Faces Gallery & Gastro Bar. That means the garden is getting smaller.

• The Dara Pirom Palace Museum is half an hour drive north in Mae Rim village. The museum is not a palace in the Western sense, but a historic wooden mansion which was home to the famous Lanna princess Dara Rasami (wikipedia.org), who was one of the consorts of Chulalongkorn, King Rama V of Siam. Dara Rasami was the daughter of Inthawichayanon (born as Prince Inthanon), the 7th Ruler of Chiang Mai from 1870 until 1897. Doi Inthanon was named after Inthawichayanon. Dara Rasami was also a pwan in the fear of King Rama V of Siam of the annexation plans of Britain in the 1880-ties. The admission fee is 20 baht per person.

• Lanna Traditional House Museum - This collection of teakwood houses is an open-air museum, and part of the Centre for the promotion of arts and culture, Chiang Mai university (CMU). It is not far from town, located between the old city and Doi Suthep on Doi Suthep road. Entry fee is 20 baht.

• Wat Ket Karam or Wat Sra Ket is a small but nice temple on the eastern riverside road, and it has its own little museum.
• Wat Ket Community Traditional Museum is located inside the Wat Ket temple grounds; it is a somewhat dusty collection; varied items that mostly date from the early twentieth century and perhaps the late nineteenth; like textile, photographs, statues, phones, radios, swords and daggers, old currency and household items. The black and white photographs of old Chiang Mai are interesting. An eclectic collection of beautiful, weird, interesting, bizarre, religious and artistic objects. No entry fee but there is a donation box.
• The Wat Ket area has many interesting old houses which have been turned into galleries and cafe's. Some of the trendy restaurants are very popular at night, and in the afternoon there is a beautiful view of the Ping river to enjoy.

  

• the McKean Rehabilitation Center and Hospital is not a museum but an interesting and historic place. In 1905 Dr. McKean got permission to establish a leprosy colony or leper asylum on a large island in the Ping river. Now the colony has been turned into a rehabilitation center between the many large trees; and it is surrounded by teak plantations. The hospital, colonial houses, church and the many small dwellings for the leprosy patients are still there. thenativegipsy.com
  There are plans to modernise the area, and create a McKean Rehabilitation park.

  McKean is about 10km south of Chiang Mai, just past the ancient city of Wiang Kum Kam. Just south of McKean's entry gate you can drive past some quaint houses and the quirky Suebnathitham Church which seems to be protestant.
  

• Wat Jed Yod is probably one of the least visited major temples because it is located outside of the old town in an inconvenient place. Jet Yod translates to "seven peaks" and refers to the seven chedis which top a structure in the temple complex. It's a very unusual temple building because it is a copy of the Mahabodhi Temple at Bodhgaya in India. It was built in the fifteenth century to host the Eighth World Buddhist Council.
  Wat Jed Yod is located on the highway which rings Chiang Mai; it is right next to the Chiang Mai National Museum. Both places are not directly connected however, and signage is minimal so you might want to use a smartphone with GPS map to find it.

• Wat Ban Den is about an hours' drive up north on the way to the Sticky Waterfall (Bua Thong waterfall), just east of Mae Taeng in the small Inthakin village. It is a relatively unknown Wat and not signposted in english so you'll need a GPS map to find it.
  Wat Ban Den is one of Chiang Mai’s most remarkable and surprising temples; and one of the largest temple complexes in Chiang Mai province. The complex contains a large number of structures including an ordination hall, a viharn, a meditation hall and several other buildings. A few large mythical Naga serpents guard the Wat on each side of the stairs, and all over the temple grounds are white lion figures called Singha.
  As you probably guessed from the Naga serpent photo below; the wat is relatively new. It was completely renovated in 1988 by the abbot Kruba Tuaengg, who aimed to establish a Buddhist wat with spectacular effects.
