The Kakum canopy walk, and the sweat that comes with it

Kakum is a patch of proper rainforest an hour inland from Ghana's castle coast, and
the reason people go is a walkway strung between the trees about forty metres above
the forest floor.

It is seven linked bridges, plank underfoot, rope and netting at the sides, each one
running from one big tree to the next. They move. Not alarmingly, but enough that you
walk in a particular way, and enough that the people who do not like it discover that
about themselves fairly early on. There is no way to turn round politely once you have
started, which I suspect is also part of the design.

What you get is the canopy from inside: you are level with the tops of trees that you
would normally be looking a long way up at, with the forest floor invisible somewhere
below through the leaves. It is green in every direction and the noise is all insects
and birds. The park holds forest elephants and a few hundred bird species, and we saw
none of the former and did not know enough to identify most of the latter.

The thing nobody had told us about was the heat. You walk uphill through closed
forest to reach the start, and by the time we got onto the first bridge we were
already finished. It is a sweat bath, completely still, with humidity that does not
move. The walk itself is short. Getting to it, in that air, is the effort.

Worth it? Yes, and mostly for the perspective rather than the wildlife. Go early, take
more water than you think, and accept that you are going to arrive back at the car
looking like you swam there.
