Nope. Boma looks out onto a bunch of plants and foliage, mostly. If you head upstairs to the lobby and out to Arusha Rock, you can see plenty of animals!
Boma's great, by the way; don't let the lack of animal viewing deter you!
You cannot see the animals from Boma, but they are just outside the resort and you can stop by and see them there.
When we ate at Boma we went about an hour early just so we could walk around and look a the different viewing areas. Sometimes there is a cast memeber there to answer any questions you might have.
The lobby is beautiful and there is plenty to look at inside and out!
You won't see any animals but I love BOMA and it is a must do for every trip. Just get there a little early so you can explore the lobby and go out back to see the animals.
