The mokoro rides in were lovely, I felt very secure. We definately sped up when hippos appeared, but the polers were very good.

The 'nature walks' were a bit of a let down - we saw a lot of poo and tracks, but only saw some actualy zebras. Our guide was also slow and was constantly on his cell phone. We had a to throw a million questions at him to get info about tracks and animals out of him. Sunsets were brilliant though, and we got to witness as epic lightning storm on our last night.

It was way too hot during the day to do anything, so we napped, played cards in the shade and swam a lot. Also learnt to do some poling by the willing guides. The campsites were obviously reused frequently, but they were still 'in the bush' and very rustic.

I guess something like this depends on who you get as your guides. Our group had 6 polers, and about 3 of them were engaging, enthusiastic and friendly. The other 3 didn't really talk to us, and seemed bored the whole time.
It's unfortunate that you have to tip them as a group and they split it, as there were some who deserved a tip, and others that I didn't want to tip at all. I also didn't like the pressure to tip - our Nomad guide said a minimum of 15 USD a day, regardless of their service.

As part of our overland tour we took a 2 night mokoro/camping trip into the delta. I really enjoyed this trip. We rode out about 1.5 hours on the mokoro and spent a couple days taking nature walks and mokoro rides while wild camping. It was a wonderful experience, the best part being the mokoro rides.

There were a couple of negatives for this tour. First, they make it sound like they will just pole out into the delta and spontaneously pick a spot, which is an out and out lie. They have probably two to three spots they rotate through as the water levels go up and down, but they know exactly where they are taking you--it's not that far into the delta, and all the campers (4 separate groups with 4 - 10 campers a piece on our tour) will be staying within about a 1/2 kilometer radius. And there are many, many flights much farther into the delta every day that you will hear every 15 - 30 minutes during daylight hours, which somewhat spoils the illusion that you are in the middle of nowhere. Our guides had cell phone service while we were there so it couldn't have been all that remote.

The nature walks are OK--we saw lots of poop but not so many animals. The best part was that we had some very dramatic sunsets and moonrises because we were there during a full moon. They won't let you walk around on your own at all because of fear of animals that we never saw or even heard. We took long naps both of the days we were there and generally had a very relaxing time. Wish I had brought a deck of cards or some games. If I ever go to the delta again I will definitely do a fly-in so I can compare the experiences. I felt like I was missing out a bit hearing all the planes fly by overhead.
