The North Base Camp is in Tibet. These camp is a rudimentary campsite on Mount Everest that are used by mountain climbers during their ascent and descent. If you want to visit it you need to have a permit (ask in a travel agency) and buy a tiket to enter. There is a bus that brings you to the base camp but if you are not going to climb you just can look through a small mountain. if the weather is good you`ll be lucky!! Mount Everest is amazing from this side!
