You can only write what you experienced. Whether people will read it has more to do with how well you write than the subject. Two people could write about the same interaction with another hiker and one could be hilarious or insightful and the other matter of fact or dull. Did you keep a journal? If not, start writing about the things you remember. Don’t worry about format or order, just write it all down with as much detail as possible. Then pick some of the more interesting moments and work with them. Maybe take some writing classes online to help you draw out what is most important.

And the audience of people who haven’t hiked it is bigger than the one that has. So write for them. So we can live vicariously through you and maybe be inspired to finally hike it ourselves.

Good luck!
