I first did the walk in 2000 when I remember it being a lot scarier. This time it was a walk in the park.
There is a bit of a climb but unless you are super unfit it's not exactly challenging. Reading some of the reviews to would think you're climbing Everest. In reality it's a few steps which are readily manageable by any fit person. If you're obese or unsteady on your feet you are probably not going to enjoy yourself.
The big headache is the road to Kakum from Cape Coast which is truly horrendous. It's not as bad as it used to be, apparently, but it's a disgrace nonetheless. You will wreck anything other than a decent four wheel drive and, if you break down, the RAC isn't a phone call away.
The walk itself is very do-able. It's a clever contraption of normal steel rung ladders strapped together in a complex netting structure put together by two Canadian engineers and some Ghanaians who helped.
It's definitely a bit wobbly but, hey, so is life itself. So get a grip on your fears and just do it!
Also stop off at Hans Cottage to get a selfie stroking a crocodile. Yes, really!
