Stop at Chiang Khong, on Thai side of border, before continung next day to Laos after a trip day long from Chiang Mai in minibus. Much nicer border town, then I expected.
Town was still celebrating Sonkran festival. The normal 3-4 days celebration lasted here much longer than in Chiang Mai.
The crossing Mekong river into Laos by small boats is an adventure by its self.
