Hermiston is a very small town, and thus there isn’t a whole lot of major attractions to choose from for what you are looking to do. There are however two small parks; Belt Park and McKenzie Park, both of which are right inside of town, and are decent spots to chill out and smoke. You could do some people watching or do your own thing. If you’re looking for privacy you’re just going to have to make yourself more private, there’s not a lot of secluded areas besides out of town. While you’re there though, be sure to check out The Neighborhood Dudes. It’s a little bar with a great atmosphere you will probably fit right in at.
