My husband and I were first time seasonals at GRO this year, and we could not be happier. Nanette, Jesica and the staff are all great, making this a great place to get away from home. The grounds are kept clean, and the amenities they provide are very nice. We can't wait for next season to start! If you are looking for a nice, quiet and friendly place to go, this is your place for sure.

Loved our last 5yrs being a seasonal camper at GRO!! The ownership, staff and service were great! Made lots of freinds and great memories here. Wish we would have become a seasonal sooner. If we were not relocating out of state, we would still be a seasonal here! Thank you GRO for a great seasonal camper experience!!

Absouletely love this place, the staff are excellent and wonderful. My family enjoys coming here. I would highly recommend Green River Oaks Resort to anyone looking for a clean and well kept campground to come and enjoy either peace and quiet or activities for the kids.

We have been coming to this place for the 5 to 7 years. My personal opinion is that this place is starting to decline. While there are improvements being made to the facilities, there are very limited employees there during the week. The weekend has limited activities for kids, the smaller pool was very cloudy and not very clean, an employee who drove past the garbage in front of our site and told... We have been coming to this place for the 5 to 7 years. My personal opinion is that this place is starting to decline. While there are improvements being made to the facilities, there are very limited employees there during the week. The weekend has limited activities for kids, the smaller pool was very cloudy and not very clean, an employee who drove past the garbage in front of our site and told us that garbage pickup doesn't happen until Friday (which wasn't told to us) and then didn't offer to take the 1 bag on his cart, hours reflected for the store are different than what their app says and not very friendly times for check in. I know alot has happened within the past 2 years but I feel like there is alot of reactionary measures vs. proactive measures. Rentable campers are damaged, multiple lights out. I really hope for the best for this family with their continued improvements.
