I visited yesterday afternoon. I must say, I picked the right time to visit. Late afternoon in early September when kids are back in school. As I peacefully walked through American Trails, I could barely believe it was a brand new exhibit with the lack of people there. I loved that!
I went through the entrance starting from Elephant Trails. You descend down the path and there is a small waterfall on the left hand side. When you reach the main level, you come across the North American river otter exhibit. It was a naturalistic exhibit with many vantage points. You could walk 3/4 around the exhibit. There's also a lower level where you can see the otters swimming underwater. It is definitely an upgrade from the concrete hellhole they were in at the Small Mammal House.
If you veer off to the left of the exhibit, you are taken to the back path featuring the raven exhibit and the beaver exhibit. The raven exhibit is built into the hillside and gives the birds plenty of room to roam. The beaver exhibit is quite spacious with two pools and a replica of a dam. Hooded Mergansers also share this exhibit, although I did not spot the male one.
Next, also built into the hillside, is the grey wolf exhibit. Most of the exhibit is covered with mesh. However where the pool is located, it is open space to see the wolves with no barriers. There's also a glass window just past this point. The yard is quite long and many hiding places for the wolves. Across from this exhibit is the bald eagle exhibit. There are not a whole lot of vantage points. From a distance, you can see it behind the seal exhibit, but if you get up close, you see it from the side, and there are diagonal planks of wood blocking the windows. However, I did find a perk of this area as it was actual woods and I spotted some deer on the hillside both times I visited the exhibit.
The seal and sea lion exhibit both seemed smaller than I anticipated. The seal exhibit right now is fair in size for it's lone seal. However, when the acquire a few more seals for Adventure Aquarium, they will not have enough space. They will have to rotate groups. The sea lion exhibit is a bit deceiving because the pool area is bigger than it appears. You notice this when you go downstairs underneath the stadium seating to see underwater viewing. The sea lion exhibit has nice vantage points with mesh around the exhibit, a large glass window to half way into their pool so you can see both land and water (with brown pelicans occupying the center rock). Then the complete underwater viewing is below the stadium seating, as I mentioned before. I was a bit surprised as I did not see the waves or movement of water in the pools. Maybe they are still working on this or it was very subtle.
Two other areas which seems closed off was the wading pool and the cafe. The pool was drained so it was easy to find the hidden treasures. The cafe was also closed -- perhaps it's only opened on weekends or lunch hours.
This is a very solid addition to the zoo. I am thrilled pathways are open now and it's an easier way to back track to the entrance. It's also nice to look up on the hills, with the elephant walking trail on one side, and the siamangs/gibbions on the other side. I will be posting photos of the exhibit in the next couple of days. Please feel free to ask me any questions on things I may not have covered.
