1. Pyin Oo Lwin, Myanmar

The city with an altitude of 1,070 meters (3510 ft) above sea level is a bustling place with an abundance of fresh fruits and flowers, mainly for the enjoyment of well-to-do locals. The mercury drops under 10 °C (50 °F) in winter, freezing by tropical standards. Travelers come for the refreshing air, beautiful scenery, and what remains of the Old World charm.

2. Sapa, Vietnam

Sapa has a lovely view and with a mean annual temperature of 15.4 °C (59.7 °F), making it favourite summer getaway spot for wealthy businessmen and an ideal place for everyone. Today, “the Tonkinese Alps” is still worth visiting for its rich culture of Hill Tribe minorities and breathtaking views of lush mountains and rice fields.

3. Xam Neua, Laos

Xam Neua is one of the most remote places in Laos. The real reason why travelers come to this quiet town tucked away in the northeast corner of the country is to use it as a jumping point for waterfalls and caves near Vieng Xai, Hintang Archaeological Park, as well as other eco-tourism sites in the province.

4. Loei, Thailand

For a local experience in Thailand, look no further than Loei. The whole province in general has a cooler temperature compared to the rest of Thailand, which makes it downright enthralling for local Thai tourists who fancy spending their leisure time at the kitschy riverside town of Chiang Khan and relish the chance to wear their winter clothing at Phu Ruea National Park, said to be the coldest place in the country (Mt Phu Ruea is 1,365 m or 4,478 ft tall).

5. Lake Sebu, Philippines

While Baguio is the go-to cool destination in Northern Philippines, Lake Sebu is dubbed the Summer Capital of the Southern Philippines. Situated on an elevation of approximately 1,000 metres (3,300 ft) above sea level, the temperature here rarely rises over the 25 °C (77 °F) mark. Aside from the eponymous lake and the legendary dream-weavers, there is also the famous Seven Falls which makes for a great location for the zipline.
