Do I have to book in advance to stay in a hostel?

It's rarely mandatory to book in advance, but it gives you one less thing to think about when you arrive. If you are travelling in high season and the hostels seem to be near capacity, you might want to consider this option.Many seasoned travellers don't book hostels in advance and prefer to have the flexibility to change their plans, but it's a good idea to think of some alternatives before you arrive. It's recommended to book in advance during peak periods, such as festivals or summer vacations.

Is it necessary to bring a sleeping bag to a youth hostel?

No, hostels should always provide this service and beds are usually already made upon arrival. You may need to return the sheets to the reception when you leave.

Do you have to bring your own towel to a youth hostel?

Yes, towels are very rarely provided in hostels, which is one of the main differences from hotels.

Are youth hostels only for young people?

No, that's the simple answer to that question. The idea that hostels are full of gap year students is a myth. Of all the people you meet in youth hostels, probably less than 10% are under the age of 20 - although this varies from place to place and hostels in larger cities tend to attract a younger crowd.In most cases, travellers are likely to be in their 20s and 30s, but fewer and fewer establishments impose an age limit, and many much older travellers choose to stay there as well.
