Mount Kadam is a peak still full of mystery. Hiking groups haven't penetrated most of its areas in years, if ever. It is a wild and huge area with much potential as a hiking destination. It is also possibly the most beautiful of all the Karamoja mountains.
The route here is a hypothetical created in View Ranger. It hasn't been done to my knowledge.
Out of Namalu or Nakapiripirit, take bodas as far as possible. At the Amudat side, once you are back on decent trails, have a local call you a boda to get you to Amudat to save some kms, or just hike the whole way.
A good place to stay and leave your car is the Hillview Guesthouse in Nakapiripirit, which is about 25k per night without food. They are familar with hikers and their needs and can help you find a guide. Payment to guides/porters is about 20k per day. Benjamin has a great reputation but is hard to track down. Anne, the manager at Hillview, is your best bet in finding him. You can also keep your car parked inside their compound until after your hike. If you finish in Amudat, you'll need a car or boda to bring you back to to Nakapiripirit or Namalu, which could take around an hour.
There is good trail on all sides of Mt. Kadam. For example, you could start from Amudat, Namalu, or Nakapiripirit and possibly elsewhere. However, these trails have never been linked up by hikers to my knowledge. So, just hike up and back from any of the sides if you aren't confident in the full traverse.
Like with other hikes in Uganda, you will need a local guide to ensure smooth relations and access to the mountain. See the general information section for guidelines on finding and managing a local guide. Alcohol and kat consumption here is pretty common, so be vigilant with your guide to ensure they are fully sober.
Groups commonly hike Kadam in 1-2 days, but it is a huge area and you could easily spend more time exploring it.
Special Advice for Kadam: I usually just show up and arrange things in Uganda the day of or day before a hike or climb. However, if you give Anne at Hillview some advanced warning that you are coming, she will help prepare things better for you. This can really help in preparing a quality guide. Anne's number is 0776 589 937.
The path is shaded most of the way. It can also be pretty muddy. Be prepared to turn around and head down if the trail runs out. Kadam can be very bushy, making progress terribly slow. As I have not yet found a completed trail for the full traverse, perhaps better to plan to hike up and back one of Kadam's sides.
