Leaving belongings at a hostel after checking out

Generally hostels do not have long term storage -- just don't have the space. I am confused. If you don't need the stuff, why are you bring it. That does not make an sense. And storage facilities tend to be expensive beyond a day or two.

I'm traveling from my country and plan to stay long term in Europe for school. I need my stuff long term but not to hike 300k. Do you have any alternative.

Any idea where you’ll be going to school? If so, perhaps you could contact the school to see if you could send some of your belongings ahead. Or perhaps after your at school, have things mailed to you there from home.

Certainly contact the hostel and see what they say. Second, take what you need for a hike and have the balance of you things shipped to you at a different address. Where are you going to school?

This may or may not fit with your travel schedule, but FYI here's what my daughter did a few years ago when in a similar situation. She had a semester's worth of clothes, books, etc., to haul to London, but planned to travel on the continent for several weeks first. She put it out on Facebook that she needed to leave a large suitcase in London from date-to-date and wondered if anyone could help her. Turns out an old camp friend had a sister in London; daughter was put in contact with sister, and so daughter landed in London, left her luggage with sister, then took cheap flight to Paris. If you are on multiple social media sites, perhaps someone in your past might be able to help you make a similar sort of connection....? If that doesn't work, I suggest you google "luggage storage in...[city]" and see what you find. There are storage facilities that will likely store it for you for 5-15 euros/day in pretty much every major European city, probably within walking distance of that city's train station.

Most major airports offer long term storage (up to a few months) of bags.

I did something similar; I needed to end up in France where I had a summer job but wanted to walk part of the Camino first. I flew to Paris and paid to store the bag I needed later at the airport, then headed off to Spain with just my backpacking bag. When I returned, I picked the other piece of luggage up from the airport and was on my way.
