Solo Travel Destination for August 2026

I have the week of August 16th off this year and am looking to book a solo trip. I am from CT, USA so keep that in mind in terms of cost of transportation and everything. I’m just looking for some recommendations of where I could get (open to driving or flying) for not extremely expensive that I could fill a week alone and not be bored or anything. I very much prefer nature oriented travel but am also a very flexible person and traveller. I have some flight points too so flight wise I can be a little more cost flexible but still nothing too too crazy. Let me know if you have any ideas!
