Thanks to Simon Collis for the following updates:
“I visited Nyungwe at the start of March. The new pricing is now operational, as per the guidebook. The only difference is that there is a separation between walks under 5km ($40/$60/$80 for foreign visitors for 1/2-3/4+ days) and walks over 5km ($50/$70/$90).
The new visitor centre at Uwinka is completed, looking lovely and, as you say, was due to open at the end of March. My impression was that the canopy walkway might have been a little behind schedule, but it should be up and running by now.
Nyungwe generally was amazing and I’d recommend it to anyone.
