guest houses

Though the vast majority of Hong Kong accommodation is within the city, there are places to stay outside the main urban areas. Some are hotels, including in Sha Tin (still urban, but in the New Territories); while there are small village guest houses in wilder places, including several you can only reach by hiking: these really allow you to stay "away from it all". (Not all the smaller places are licensed, perhaps). Can make interesting choices for budget accommodation.

There are also plenty of campsites - though not (yet) covered here.
