No signs... Located at farthest southern tip of park, 5 sets of yellow posts stand out in a small parking lot with picnic tables behind. Lake is within view. Park has an aged feel with road repairs needed, but just enough activity to know it is still used.
We read previous reviews and decided a $15 camp spot would be ideal. Sites were all very level and I didn't unhook from my 37 foot camper. I used my surge protector on 4 of the 5 camp spots electric boxes and all were live and looked newish. No water, but this is the first week of April and there are irrigation boxes for each site so water may be available later. Hiked in the very nice park next door, and felt very safe.
We were very pleased with our stay at Fair Park! We were on US Hwy. 287. You turn onto Commercial a few blocks where it tees with Ave. I. Directly in front of you will be the entrance to the park. As you come in you will go to the right. Follow the road and you will see the parking area on your right. Each site has a yellow bar where your electric box is located and the water tap is under the green cover in the grass just a foot or so away. You will be able to easily walk to the lake where lots of ducks live. Be warned that there is a large baseball field adjacent to the RV area and the fans park right by the rigs. Also, weekends get busy so be early or be left out!
