Spotted a section of paved path while driving with a friend today. On our way back I made sure to watch via Google Maps, and find out if it was a park, and sure enough it is.
Graphic design aside, the above map is from their website (hooray for websites in 2022), and it shows that the outer loop is just over a mile. And from the looks of things I could switch up some of the turns here, make loops within loops, and get some nice mileage in without going nuts, or being too far from my car.
