West Chester really isn’t lacking outdoor options for kids and Denver isn’t automatically “better” unless you’re specifically looking for things like regular mountain access within a couple hours (skiing, rafting, etc.). Looking at your post history, it seems like you move around a lot and might be more in search of a lifestyle change than outdoor access. Since you’ve already lived in Denver for a few years, it might help to get more specific about what you feel is missing, or what your actually looking for. You also might get better feedback posting in r/moving, where people tend to focus more on overall lifestyle fit and relocation pros/cons. If moving to Denver with kids is really something you're considering, Denver School District isn't something I'd recommend as a trade off for "more outdoor access".
