Chiang Mai is northern Thailand's cheapest cultural heavyweight: dozens of working Lanna temples charge nothing, a bowl of khao soi runs 50฿, and red songthaews cross the old city for 30฿. Three days here can cost less than one day in Bangkok.
Chiang Mai's oldest temple (1296 CE), founded by King Mangrai as his construction camp. Free entry, open 06:00–18:00. The elephant-buttressed Chedi Chang Lom and two ancient Buddha images sit in a quiet compound; walk east along the surviving north wall to Chang Phueak Gate.
A family kitchen behind Wat Kuan Kama serving one thing: khao soi at 50–60฿ a bowl, chicken or beef. Open Mon–Sat 10:00–14:00 only, and they close the moment the pot empties — usually by 13:15. Pickled greens, shallots and lime come free on the table.
The 1935 provincial court building now holds full-scale Lanna dioramas — lacquerware, monk fans, teak house interiors — for 90฿ (free for under-10s). The square outside with the Three Kings bronze is permanently free and shaded by rain trees.
The intact southwest bastion of the 1296 wall, with the fountain-lit moat running north from it. Locals jog and fish here at dusk; benches face the water and cost nothing. Vendors sell grilled pork skewers at 10฿ and sticky rice at 10฿ a bag.
Chiang Mai's 1910 three-storey trading hall. Ground floor is northern food — sai ua sausage 20฿ per stick, nam prik num chilli dip 25฿, crackling moo yong by weight. Upper floors sell hill-tribe textiles at a third of Night Bazaar prices. Open 05:00–18:00.
The university market where Chiang Mai students eat. Rice-and-two-curries plates run 40–50฿, fresh mango 30฿ a kilo, and the fried chicken stalls sell half a gai yang for 60฿. Busiest 11:00–14:00, almost entirely Thai customers.
A 1370 forest temple whose field of whitewashed mausoleums holds the ashes of Chiang Mai's royal line. Entry is free; the open-sided wihan with its 500-year-old bronze Buddha catches afternoon light. Monk Chat runs here Mon/Wed/Fri 17:00–19:00, also free.
A tight strip of carts just outside the north gate: khao kha moo (stewed pork leg on rice) 50฿ from the cowboy-hat lady, boat noodles 40฿, roti 30฿. Plastic stools, no menus in English, running 17:00 until roughly midnight every night.
A 1297 forest monastery built into brick tunnels beneath a mound, with a lake, a fasting-Buddha statue and 'talking trees' hung with proverb boards. Grounds free, tunnels free, the small museum 20฿. Songthaew from Suthep Road drops you at the gate for 30฿.
Behind the Nimmanhaemin cafés sit the workers' canteens: 45฿ khao kha moo, 40฿ pad kaprao with fried egg, free clear soup refills. Nimman Soi 13 and Soi 17 hold the cheapest run, open 08:00–15:00 on weekdays.
A limestone cascade at the foot of Doi Suthep, inside city limits and free to enter. Locals swim in the lower pool and picnic on the rocks. The mineral crust grips bare feet so you can walk straight up the falls. Open dawn to dusk.
The unmarked roadside lay-by halfway up the mountain, where the whole grid of Chiang Mai and the Ping valley opens out. Free, no gate, no ticket booth. Red songthaews heading down will stop if you flag them; 40–50฿ back to the old city.
