The hot springs are powered by granite bedrock fractures that allow rainwater to percolate deep into the earth, heating and mineralizing before returning to the surface.
The water contains high concentrations of sulfur, which is traditionally believed to assist in skin treatment and circulation.
The geyser-like fountain at the center of the park can reach heights of up to 15 meters depending on pressure fluctuations.
The park grounds contain a dedicated 'egg boiling' area where visitors use bamboo baskets to cook eggs in the geothermal water, typically taking 5 to 10 minutes.
The temperature of the source spring is hot enough to cause severe burns, leading the management to fence off the primary geyser vent.
San Kamphaeng Hot Springs features natural geothermal activity with water temperatures reaching over 100 degrees Celsius at the source. The site is characterized by high sulfur content springs that jet water into the air through natural pressure. Visitors can access mineral-rich soaking pools, private bathing rooms, and public foot-soaking areas. The surrounding grounds are landscaped as a public park with walking paths, flower gardens, and stream-side seating. Geothermal energy from the springs is utilized on-site to facilitate egg-boiling stations for tourists. The water is sourced from deep underground reservoirs and pumped to various pools to regulate temperature for safe human immersion. The site operates as a regional recreation area managed by the local district authorities. Its location in the Mae On District makes it a common stop for travelers moving between Chiang Mai city and the local cave systems.

Bring a small towel and a change of clothes if you plan on using the public or private soaking pools.
Purchase eggs from the on-site vendors to participate in the traditional geothermal cooking activity.
Visit the shaded foot-soaking areas located along the stream for a more relaxed, cooling experience compared to the central geyser.
Wear comfortable, easy-to-remove footwear as you will likely be taking shoes on and off frequently near the pools.
Do not attempt to touch or stand directly over the main geyser vent due to extreme water temperatures. Avoid buying tourist trinkets at the entrance stalls as prices are significantly marked up compared to city markets.
Modest swimwear is expected in public pools; avoid revealing clothing. Respect local norms by keeping noise levels low in designated relaxation zones.
