From Bangkok, I took the sleeper train to the north. The train leaves late afternoon and I arrived around 05:00 in the morning in Chiang Mai, the cultural capital of the north. This city is a lot quieter than Bangkok and is located in the middle of a mountainous, green region. The atmosphere is relaxed, the people are friendly and there are dozens of temples to explore. Among others, I visited Wat Phra Singh and the hilltop Wat Doi Suthep - with stunning views of the city. We were here during sunrise. This is very worthwhile. I also took a cooking class, one of the most enjoyable experiences of my trip.
After four days in Chiang Mai, I left for Pai, a small hippie village in the mountains. The route there (about three hours in the minivan with endless curves) is notorious, but it's worth it. You can also make this trip by scooter, but unfortunately there were no scooters available during my stay. Pai is small, relaxed and surrounded by nature. Think waterfalls, hot springs, rice fields and viewpoints like Pai Canyon. The atmosphere is wonderfully laid-back and I found it a nice place to unwind. There is a bit of an island/hippie vibe. I swapped hostel life here for a while for a nice AirBnb including breakfast with three nice girls I met in Bangkok.
