@DavidBrown You can see every animal via the walking trail, but the boat ride does get visitors a little closer to a few species and the tunnel is neat to pass through. Here's an excerpt from my Snowleopard's 2019 Road Trip thread:
We then plunged into Europe’s largest Tropical House, with primates such as Ring-tailed Lemur, Black and White Ruffed Lemur, Colombian Spider Monkey and White-handed Gibbons in side habitats and ‘Birdy Bush’ for Rainbow Lorikeets. There are free-ranging Leaf-cutter Ants, as we saw a colony on a tree trunk and then in a separate area we again came across hundreds of ants roaming the cement floor and quite far from their original location. When a Rodrigues Flying Fox flew by while we were looking at the ants, a jungle atmosphere was authentically created. There are free-roaming species that are probably next to impossible to locate, such as Tokay Gecko and Madagascar Giant Day Gecko, plus small, almost hidden terrariums for the likes of Mexican Red-knee Tarantula, African Clawed Frog and various poison dart frogs. These exhibits are near the boat ride, which we took, and it is a pleasant-enough 10-minute journey with one part going past a crashing waterfall and then a tunnel, both of which are difficult to see from the main visitor path. The last section is the indoor quarters for the elephants, once again up there with the best in Europe. There are numerous birds flying around, an eating establishment, a treetop canopy walk for those brave enough to take to the heights, and a kid-friendly atmosphere.
