Why people fly Houston to Islamabad
Houston families with roots in Islamabad, Rawalpindi and the north often travel for weddings, religious occasions and the summer holidays. Islamabad is also a gateway to scenic destinations such as Murree, Nathia Gali, Swat and Hunza, so a family visit can easily turn into a mountain holiday.
Best time to travel
Spring and autumn are ideal, with clear skies and mild weather. Summer is warm, and many families escape to the hill stations. Winter is crisp and sunny. Monsoon rains turn the Margalla Hills a lush green in July and August.

Rawalpindi's Raja Bazaar and the ancient ruins of Taxila are good for a day out, and the Margalla trails are popular for early walks.
Planning tips
Pick a layover that gives you time to stretch and rest, check baggage allowances for gifts and keep your passport and Pakistani ID documents together.
