Illustrative picture

What a single figure hides

Spirit of Siam at ฿18,000 with a room is a different product from a training-only fee. If your budget is a training fee, you are shopping for sessions and a separate bed. If your budget is ฿18,000, you are shopping for a package, and you still need to read what the meals are.

For a drop-in, ask the gym for its current single-session price with the date. That is the only stable figure.

Air quality

A Thai government note dated 10 Feb 2026 says PM2.5 tends to rise from late year into early year, including in 17 northern provinces. It names forest fires, agricultural burning, traffic, industry, and haze from across the border, plus high pressure and calm wind. A review that used Pollution Control Department stations for 2019 to 2021 reported northern levels rising around mid-January, peaking in March, and falling by mid-April. That is not an AQI for the week you travel, and it is not a forecast. Read the official monitor for your dates. If you have a lung condition, ask a clinician. We are not giving a mask protocol.

Getting a fair comparison

Compare package with package. Spirit of Siam at ฿18,000 is not "twice as expensive as Phuket" when Phuket's Tiger standard room is ฿42,800. The products differ. The price page lines up named fees.

Flights into Chiang Mai, visa days, and whether the gym has a room (66 of 266 Thai listings say yes, 181 are blank) decide the trip as much as the fee does.

A simple week, with the numbers we have

A weekly pass and five drop-ins are different products. Read the label. Spirit of Siam at ฿18,000 is a month with a room, which is about ฿4,500 a week if you stay the whole month and do the division yourself. We are not saying the gym will sell you a quarter of that package.

Food, the flight, and a visa-exempt stay of up to 30 days are outside these figures. The visa page has the official wording. This page will not convert baht to pounds.

Morning sessions in Chiang Mai are the product. If you arrive at noon you have missed the reason the drop-in was cheap. We did not copy a timetable from Spirit of Siam, so we will not pretend every gym starts at 7am. Ask. A gym that only runs evening classes is a different fit for someone who came for two-a-days. No training fee tells you the schedule.
