There is also the whole brand ambassador/being sponsored/paid by local tourism boards element, maybe down the line if you feel like social media growth is something you are interested in. Monetizing blogs without the social media focus is a bit tricky in the current climate (I speak from experience, I never had enough of a niche or willingness to brand myself). But I think travel has really wide parameters for who people like to consume content from, especially the more niche interests like caravanning.
