There are three main viewing areas - from behind a fence in front of the tank on the main zoo path, an amphitheater-style seating area above the tank on the opposite end, and an underwater viewing gallery where visitors can watch the seals glide through the water. Signage around the exhibit teaches guests how to tell seals and sea lions apart. The zoo's pinnipeds are trained voluntarily twice a day, and given fish treats as rewards.
