No trip to Chiang Mai is complete without a trip to the Doi Inthanon national park. Part of the Himalayan mountain range, Doi Inthanon is Thailand’s tallest peak at 2,565 metres above the sea level. You will see gorgeous skylines and an amazing cloud forest. The park is quite big (482.4 km²) so if you really like hiking plan 2 days there instead of trying to fit it all in to one. The climate is typically tropical and fairly cool on the summit of Doi Inthanon. In winter the average temperature is 6 °C (43 °F) in January and temperatures can sometimes drop below 0 °C (32 °F). Most of the waterfalls within the park have relatively good flow of water all year round but the best season for water flow is during the rainy season. One of seasonal highlights of the park is the blossoms of Siamese sakura flowers covering trees in pink during late January and February. The park is also one of top destinations in the country for bird watching.
