Camp Nauvoo is a nice, church operated, park only 5 minutes from downtown Nauvoo. We stayed one night on our way to Minnesota. The sites are sunny and all are pull-through.but some have shade. The park streets are gravel with concrete pull-through sites. The park is very quiet. Great value for $32. Full hookups.
Stayed in campsite#10 which has no shade. It was a concrete pull-through with more than enough parking for my TT and truck and grass on either side. The site included: picnic table. Utilities were located in different spots. 20A/30A/50A electric in the middle, water near the rear, and sewer near the front. Site was level. No neighbor on passenger/awning side.
AT&T had 3 bars of LTE and Verizon 1 bar of LTE service. AT&T Speedtest: 56.8 Mbps down, 9.3 Mbps up. Free WiFi available, but I had trouble connecting.
If you are southbound on Illinois Hwy 96, the left turn off the highway is very sharp and steep. Might be easier to continue about a mile south and use the scenic turnout to turnaround. It is a pull-through turnout. Then, turn off the highway on the right.
Would stay here again. We camped at Camp Nauvoo in a Travel Trailer.
