Omani people are warm and welcoming. It’s not unusual to be invited into a local’s home after a day touring the mountains or walking through the local souk. It’s considered polite to take a small gift for your host.

When entering an Omani home, you’ll likely be greeted with the scents of frankincense and cardamom, and treated to Omani coffee, dates, and halwa – a local dessert made with saffron, dates, and rosewater. Coffee is served in small cups, which are refilled until the guest gives them a gentle shake to signal they’ve had enough.
