Before lockdown, we visited Chiang Rai in Thailand.
In recent years, Chiang Rai has become one of Thailand's most popular destinations, and it's easy to see why. Beautiful countryside, some very interesting temples, and delicious local food.
A link to Phu Chasai, the hilltop resort we stayed in, is here https://phu-chaisai.com/en/ We thoroughly recommend it. Comfortable (if not the last word in luxury) accommodation, but what really makes it, is it's location up in the hills, and surrounded by beautiful countryside. It's ideal if you want to get into nature, with hiking and horse riding easily accessible
