Trekking to Everest Base Camp is one of the outstanding "must do" adventure trips for all keen walkers and hikers. It's a tough trip, taking about 18 days all in but it's totally rewarding and the views are simply majestic. It takes a few days to adjust to the altitude when you arrive - you can't go straight from Kathmandu - but that gives you plenty of time to soak up the beauty of this amazing country.
