I couldn't choose only one. I mean, both hitchhiking and bicycle touring are genuinely great ways of traveling. Both of them are very cheap. And because of that, you'll get to enjoy every single moment of your trip. However, I guess bicycle touring has to be the one that I like a bit more. Why? You can ride it long beautiful streets and views, and whenever you want to stop, you stop! You don't need to look for parking spots or anything like that. And, I think it's less tiring than hitchhiking. However, if you want to be safe, you'll need to ensure your bike at a company like https://sundaysinsurance.com/. Such simple insurance will make you feel much more confident.
