This time of the year is fantastic, a lot of blossom, warm nights and mornings, singing birds and babies of all kinds.
It is a common misunderstanding in Europe and North America that Thailand is a rain forest without seasons, that the landscape looks the same regardless of month. Our tropical monsoon climate do have three very pronounced seasons and so nature lovers should avoid the early cool season (November-December) when the birds are silent, many plants and butterflies are inactive and the nights are uncomfortably cold. The touristic guidebooks may be written by experts on bar hopping and bungy jumping and so cooler evenings might be preferred for such activities, but garden and forest lovers should focus on the active period from mid February until September.
Eco tourism is still declared an insignificant niche by the Chiang Mai tourism association, but private initiatives such as Dokmai Garden and the Tiger Trail will change that by providing expertise in finding and explaining about Thai plants and animals. The successful development in Australia and New Zealand inspire us.
