Everest Base Camp Trek

Most trekkers trekking in Nepal have done the Everest Base Camp
Trek.The Everest region, located on the eastern part of Nepal, has
some of the worlds tallest peaks, including the highest peak in the
world Mount Everest (8848m). This region is quite popular among
trekkers and mountaineers. Most of the villages in this region are
situated above the 2000m. Sherpa villages like Namche bazaar, Thami,
Khumjung, Lobuje, Pangboche and Tengboche have comfortable lodges and
tea houses. The major mountains in the region are Everest, Lhotse, Cho
Oyu, Nuptse, Pumori, Ama Dablam, Thamserku, Kantega,  Mera Peak and
Island Peak. The Sagarmatha National Park, which is located in this
region, is the highest national park in the world as well as a UNESCO
World Natural Heritage Site. The park covers an area of 1,148 sq km
rising from its lowest point of 2,845 m at Jorsale to 8,848 m  up to
the summit of Everest.
The Everest Base Camp in the Everest region has been a popular
destination for trekkers since the very first Mount Everest
expedition. One can trek to Everest Base Camp in just over two weeks.
You begin your  trek from Lukla. The trail takes the path to Upper
Phakding and follows the Dudh Kosi valley up to Namche. The trail is
filled with magnificent forests of rhododendron and giant firs and it
is a delight to walk this trail in early autumn and late spring as the
path is filled with wildflowers and rhododendron blooms. From Namche,
it is uphill all along till Thyangboche Monastery. The monastery is
located on a ridge top and offers great  views of the Everest
landscape. Passing through villages of Pangboche and Pheriche, one
approaches the Khumbu Glacier. Spend sometime at  Lobuche, which
serves as a vantage point for Himalayan peaks of Ama Dablam and
Taweche. Hike to Gorak Shep and explore Kala Pattar. Enjoy close up
views of the towering Mt. Everest, Pumori, Lhotse and Nuptse from
here. Trek down to Everest Base Camp before retracing your steps to
Lukla.

What are the permit fees to go to Everest Base Camp? Can you give some budget guidelines? I am doing research for a new edit on my eBook, Nepal: A Tourist's Manual. I didn't do a lot of trekking details simply because it's readily available elsewhere, but I'd like to put something together for the next edition.

I enjoyed your post. It sounds a lot better than I'd imagined it.
