We found River Lodge Resort to be a great campground to go to in the spring (April or May)after most of winter visitors have left and before the summer crowds. It is located on the Colorado River so be sure to ask for a beachfront site. Sites on the river have a covered picnic table and there is enough landscaping to provide privacy from the next RV. The sites are good sized and the hookups are convenient. The weather can be very warm at this time of the year and is generally wind, but if you're looking for sunshine this is the place to go. There is a boat access at the resort and on weekends there is a lot of boat traffic on the river, otherwise it is quiet. You cannot cross the Parker Dam to get to the resort as it is closed to large vehicles, but the website provides directions to get there. We would highly recommend.
Our stay at Cocopah RV Resort was great. The staff were very friendly and helpful, and I would highly recommend this park. The sites were very generous, with a large cement pad, plenty of room to park our vehicle in the site, and the hookups were convenient. A section of the resort accommodates guests who have animals (we had one dog), and there is a large grassy exercise area. The resort is surrounded by produce fields, nicely landscaped, has a security gate, and the golf course appeared to be in excellent condition. The only complaint we might make was the occasional noise of Border Patrol helicopters at night although this would not deter us from staying again. We forgot a small item in our site and the staff was nice enough to return it to us.
