If Twenty Thousand Leagues Under the Sea taught us anything, it’s that giant squid make better chess partners behind thick glass and that books should be eaten and not read under water. Enjoy the advantages of the deep with today’s Groupon: for $12, you get two adult admissions to Pacific Undersea Gardens in the Inner Harbour (a $24.53 value). Located in a floating vessel 5 metres beneath the ocean surface, Pacific Undersea Gardens surveys more than 5,000 marine animals within its aquarium and during its live shows. Traverse the pacific landscape in search of sea stars and salmon or marvel at the wolf eel and giant Pacific octopus flitting through a forest of white and crimson anemones. Guests interact with the deep blue by handling sea life at the tidal pond, testing the limits of prune-resistant hands, and exploring mysterious creatures during tours that total 45–60 minutes, including 20-minute live dive shows. Families can learn together with children’s tickets—$5.50 for ages 5–11 and free for 4 and younger.
