We would love to go white water rafting but the main company operating in the area (Savage Wilderness http://www.savagewilderness.org/water/rafting.php) will take a minimum of 3 people on a trip. It's $105 per person for a day including pick up and drop off in Nairobi (we won't have our own transport). I think the rafts take up to 6.
It would be great to hear from anyone (a single person, a couple or group) in a similar situation who is Nairobi at this time and could help us make up numbers or vice versa.
If anyone has any other tips for going about this/know of other companies please let me know. If this isn't the right forum for this, please do suggest any Nairobi based forums where I could post.
