We stayed for 3 nights on their campsite (landrover/rooftop tent), did a boatride with the lodge (excellent game viewing) so certainly recommended, game driving done with our car; did see elephants, biggest herd of sable ever seen, hippo, crocs, etc. (you can see lion and black rhino also, but need then to take a game drive with the lodge in the fenced 50 km² part of the NP)
Hippo and elephants come on to the campsite, which can give you some excitement during night. Ablutions are ok and have fences (although one elephant didn't seem to mind so much about them). Staff of the camp is very friendly, but their administrative paperwork is so heavy, it takes ages to book something or getting checked in.. so be patient from that side !!
Bare also in mind that when staying on the campsite you'll have no view on the river, but grab for that occasion a drink in the bar.

We just wanted to write and say what a truly incredible trip we at Mvuu Wilderness Lodge. We have never been treated so well, eaten such wonderful food and had such an amazing experience. The animals were fantastic and our guides were brilliant and very knowledgeable. "Willy" our driver was FANTASTIC. He was punctual, friendly, knowledgeable and very kind and efficient. We will never forget such a fantastic experience!

arrival as we were leaving too early to do it in the morning. Guide was knowledgeable and friendly. Dinner was outside with dancing and excellent barbecue. Even though we were leaving an hour before breakfast began, staff happily arranged for us to have a full breakfast and were charming. Staff were attentive and cheerful and really made us welcome. Wished we could have stayed longer.

Spent one night at Mvuu Camp and one at the Lodge (we didn't pay the full international tourist rate, by the way - couldn't have afforded to stay there if we had). We were on a holiday as a family, visiting old haunts as we used to live in Malawi. We loved Mvuu and had a great time. Had wondered what the differences between the Camp and Lodge would be. Basically the Lodge is aiming at providing you with an 'exclusive' experience. We liked both, but most of us preferred the Camp as it had more of a buzz about it. The rooms were lovely at both and the outdoor showers at the Lodge were fantastic! The food was pretty good - delicious scones and muffins for breakfast, but the desserts weren't quite as good. Frank and Danforth, our guides on game drives and boat trip and an early morning walk were knowledgeable and enthusiastic and informative.

We'd go back like a shot (but not at $500 a night for the Lodge!)
