Browse the full Bhutan library →March is cooler and quieter, April is the most popular all-round spring month, and May is warmer with increasing afternoon cloud and showers. Choose by elevation, festival dates and tolerance for booking pressure rather than a single 'best spring month.'
Who will enjoy this most
- March for quieter cultural touring and the first spring colour.
- April for broad valley walks, rhododendrons and confirmed major festivals.
- May for warmer conditions, later flowers at elevation and travellers comfortable with cloud.
- Seven to nine days for Paro, Thimphu, Punakha and optional Phobjikha.
A route that makes sense
- Begin with two Paro nights and a full Tiger's Nest day.
- Use two Thimphu nights for culture and a spring walk.
- Cross Dochu La to warmer Punakha for two nights.
- Add Phobjikha only with eight or nine days; Central Bhutan still needs 12–13 days.
What can change the plan
- Flowers do not peak everywhere at once because valley and pass elevations differ.
- April festivals can tighten flights, rooms, guides and vehicles.
- Afternoon cloud becomes more common toward late spring.
- Cold pass mornings remain possible even when Punakha is hot.
What to sort out before booking
- Reserve confirmed festival dates before choosing every hotel.
- Pack layers, sun protection and a genuine rain shell.
- Carry allergy medication if pollen is a known issue after medical advice.
- Give photographers more than one pass or dawn opportunity.
Choosing your dates
Look at the valleys and activities in your own route instead of using one weather label for the whole country. Check festival dates, road advice and airline schedules again before paying. If a missed onward flight would be expensive, sleep in Paro on the final night.
Useful answers
Frequently asked questions
Which spring month is best?
April has the broadest appeal, while March is quieter and May is warmer with more cloud risk.
When do rhododendrons flower?
Timing changes by species, elevation and the year's weather; use a range, not one promised date.
Is spring good for trekking?
Often, but route altitude, snow, rain and campsite condition must be confirmed separately.
Is Punakha hot?
It can be much warmer than Paro, Phobjikha or high passes, especially in May.
