The accommodation options in trekking routes range from guest houses, homestays, hotels and tea houses. In Kathmandu and other major towns, you will find some good quality hotels and lodges. But as you go further upwards, tea houses and homestays are the mode of accommodation. Most tea houses and homestays require you to have meals there. As you go higher up, charging your phones and hot water will cost you extra money.
Nowadays, with many trekking routes being discovered, tea houses are becoming popular and has become an excellent way of supporting the local economy.
