They are usually outdoors-based. I haven’t done any yet because I haven’t had a vacation in so long I forgot what one is! It’s good to have one where you try something new, but I think a good vacation can also include a trip to a place where an activity or sport is very popular or easier to do than at home. For example, traveling to a place where bicycling is easier to tour, places with running tours, famous hiking trails, etc. Those are good places to start because they make use of what is already there.
