Zoomazium

Zoomazium is one of Seattle's most beloved destinations for families with young children — a dedicated indoor nature-play facility located within Woodland Park Zoo on the zoo's northern side. Designed specifically for children ages 0–7, Zoomazium creates an immersive Pacific Northwest forest environment indoors, complete with a multi-story treehouse, climbing structures modeled on natural elements, sensory exploration stations, and hands-on discovery areas.

The centerpiece of Zoomazium is its indoor treehouse — a multi-level climbing structure built to feel like exploring a real forest canopy. Children can climb, balance, crawl through tunnels, and peer through windows at animal-themed illustrations. The design intentionally blurs the boundary between play and nature learning, with every surface and activity connected to the Pacific Northwest ecosystem.

For the youngest visitors, dedicated infant and toddler areas provide age-appropriate sensory play separated from the big-kid climbing zones. A nursing room is available on-site — a feature that parents of infants genuinely appreciate and that many comparable facilities lack. Staff members facilitate interactive programs and discovery moments throughout the space.

Because Zoomazium is part of Woodland Park Zoo, it works beautifully as part of a full zoo day — see the animals in the morning, then let young kids wind down in the indoor play space after the zoo circuit. Zoo membership includes Zoomazium access, making it excellent value for Seattle families who visit multiple times per year.

For families visiting Seattle with children under 7, Zoomazium is a must-visit. Its combination of physical play, nature education, and parent-friendly amenities (nursing room, changing tables, accessible design) sets a high bar among Seattle's family destinations.
