The foothills of the Himalayas (besides other, lesser known, inland mountain ranges) offer breathtaking treks. While the options are unending, it is advisable to stick to the better known treks, where it is difficult to get lost and where the help of fellow trekkers and guides can be sought.
The trekking culture as a whole, especially amenities such as trekking lodges, support from locals, well-defined routes, rescue facilities, accommodation and food can be hard to find, even on some common trekking routes. The best bet is to find a local trekking agency that organises group treks to popular destinations.
