Modes Of Trekking In Nepal : 

Tea house trek is the most popular modes of trekking in Nepal. However, camping is also a good option while trekking in Nepal. Accommodation and food are the most asked topics for anyone wishing to trek in Himalayas of Nepal. It makes sense as after a demanding and challenging day out on a trek, worries of these two things at the end of the day could spoil the whole fun out of trekking. This page titled, Modes Of Trekking In Nepal briefly explains tea house treks, camping treks and few other options available depending upon the remoteness of trekking area or region. It also explains all the modes of trekking in Nepal offered by Visit Himalaya Treks:

Camping Trek.
There are several designated campsites on most trekking trails of Nepal for camping enthusiast who wish to sleep under the stars at the feet of mountains. Though it sounds a good option only for serious outdoor loving masses, it is also a great option available in Himalayas of Nepal. Some places on popular trekking trails of Nepal get busy in unbelievable ways and it is hard to find space during the “main season”. And there are plenty of treks in the country where there are no facilities of a teahouse or a lodge. In these cases, camping is “THE” solution and usually in the context of trekking in Nepal, it is the best solution (barring some very busy and popular treks).
Camping treks in Himalayas of Nepal is an amazing experience in itself. One of the best part of these camping trek is the food during treks. As these camping treks also include a kitchen team that prepares all the meals during the whole period of trekking. In this way, it is more safer and better than the kitchens of lodges in the busy times of season.
Camping treks offered by Visit Himalaya Treks includes all meals and drinks during the whole trekking period.

Tea house Trek.
Tea houses or lodge treks in the trekking routes of Nepal are kind of a mixture of a basic motel and a diner. But the cache is, the owner expects people staying to eat at same place and feel offended if they don’t do so. The rooms are quite basic and have a common lavatory but comparing the altitude and difficulties, it is the best that is available. However, some places, like Khumbu do have some really nice lodges and also some fancy luxury lodges that can cost more than $100 per night.
In general, lot of trekkers have a misconception about food available in the teahouses. They believe it is only Dal Bhat (traditional Nepali meal with rice, lentils and curry) during the whole trekking period. But these teahouses offer a good variety of menu that has most of the western food and local food. The food on these teahouses are quite good as well (depends on teahouses).
Visit Himalaya Teahouse Treks include all three meals during the trek. (Breakfast, Lunch and Dinner)

Camp + Teahouse Trek
There are some treks (mostly climbing trips) where both camps and tea houses are used. Basically, this trek is tea house trek but camping is needed for a day or two because of unavailability of tea houses at base camps and high camps of the trekking peaks.
Visit Himalaya offers camp + teahouse trek only in the climbing treks.

Homestay Trek
Homestay is a basic version of tea house treks. In homestay, one stays in the approved local houses as a paying guest. The family shares their own local food and there are no options when it comes to food. The trek provides an unique opportunity to experience the local life and their traditions.
