The very ends of the trail, on the pool view sides, will be able to look across at the edge of the savannahs. You can also, albeit it is a long look, see part of the savannah while looking straight across the pool to the savannah from one of the upper floors.
Remember at AKL there are many places to see the animals from. There are look outs everywhere! They really do encourage seeing the animals from many different areas. I never looked at the vegatation as a way to keep people from seeing out, but rather as theming. I really feel like I am in another world when at AKL, including when I am at the pool area.
