5 Stars! We had an amazing time at this beautiful RV park! From the moment we arrived, we felt so welcomed by the incredibly friendly and accommodating staff.

The park itself is gorgeous—immaculate grounds with lush greenery, a serene pond, and a sparkling swimming pool that was perfect for relaxing after a day of exploring. The highlight for our kids was definitely the pool slide, which they couldn’t get enough of! It's such a peaceful spot, and we loved the calm, natural beauty all around us. The atmosphere is so family-friendly, and everything is well-maintained. We can’t wait to come back and make more memories here. Highly recommend this place to anyone looking for a relaxing getaway in nature!

We have stayed here several times in both the camp sites and cabins, and it was wonderful. Clean bathrooms, beautiful park, and friendly staff. They even hosted my wedding back in 2010! Can't praise this place enough!

Medford Oaks was a fantastic place to stay for a night. Clean and quiet. They also have so many amenities like a pool, basketball court, and many others! I spoke with Bradley and he was a pleasure to chat with. I would definitely come back and bring my family or friends here. 10/10!

Won't be staying there again. $50 a night for full hook up. Our spot was super unlevele. Office was closed and they already had our money. Didn't sleep good at all. Nuts fell out of trees all night long. No discount for veterans or Good Sam. Not tv even with antena.
