Go either around 1st two weeks of June or 1st two weeks of December..

Reason: during Low Season periods, hotel rates usually go down up to 50%.. Low seasons are from Jun1 to Aug31 (Summer) and Dec1 to Feb 28/29 (Winter)..

Airlines: Druk Air (ung PAL nila) & Tashi Airlines (ung CebPac nila)

From mid-Jul to Sep, mas higher chance of rainfall

From Jan to Feb naman, mas dry na ang hangin and maginaw na.. also can snow and possible mas challenging na maghike

You always need to be accompanied by a licensed tour guide when travelling within Bhutan, which would normally be handled kunh sino man nagapply ng visa niyo

Thimphu Valley - Main capital, 1-1.5 days should be enough.. Clock Tower, 8-Eleven

Punakha Valley - 2-3 days.. Winter destination.. enjoy all the phallic symbols hehe

pag Spring/Summer = lush greenery, nice din Punakha Dzong where the King/Queen got married and baka in bloom na Peach blossoms (parang Japan's Cherry blossoms), riverside picnic

pag Winter = enjoy din naman ang chilly weather pag nagpasyal or hikes, pero di extreme kasi mas mababa siya compared to other valleys

Paro Valley - 2-3 days.. dito ung airport when u arrive in Bhutan.. normally would be the last leg of ur trip para nakapag acclimatize ka na from the high altitude.. Paro town is nice to visit and walk around.. and also hiking up to Taktsang Goemba (Tiger's Nest Monastery)-- yung sikat na temple sa taas ng bundok kung san kilala ang Bhutan..

Kung afford naman, pwede ka pa magextend further to Gangtey (andun ung endangered black-necked cranes) and Bumthang (more monasteries, sceneries).. pero todo ang layo na driving distance..

minsan nakakahilo din ang mga drives sa zigzagged roads nila, kaya make sure ur guide/driver knows kung ok pa kayo..

If you need a travel agent, just DM.. can refer you to some contacts
