From March to May, Bhutan’s abundant flora is on full display and the weather is fantastic, mild with beautiful mountain views on most days. Though there is some rainfall, particularly as you get into May, the day-time temperatures are very pleasant. Rhododendron forests fill with color and if you’re lucky you may even spot the rare blue poppy, a three-foot tall species once thought only to be a myth. The famous Paro Tsechu also draw many travelers at this time of year.
