The joy of travel is that there is a destination or activity to suit any taste or interest. You can lounge on a beach, hike a mountain or sail the seven seas. Alternatively, you can connect with the locals outside of the usual tourist traps.
If you enjoy immersing yourself in a destination without sacrificing any creature comforts, then consider Nepal. It is certainly more than just postcard perfect mountains, and offers a range of activities, sights and interests to satisfy the choosiest traveller.
