Norwegian Getaway excusion for howler monkeys

They use to have a river tour to see Howler Monkeys and now I'm not seeing that excursion. Does anyone know anything about it? I think it was in Belize or Honduras? Thanks for any help!

I believe that's in Roatan Honduras. I'm not sure about a river tour, but they do have a monkey sanctuary I believe.

Belize on the other hand has the River tubing, but monkeys there would be in the wild and not a sure thing. There is also be a Monkey Sanctuary in Belize as well (Baboon and Howler) so maybe there was a combination tour that did both.
