The Lehigh Valley Zoo, inside the Trexler Nature Preserve north of Allentown, strings over 1.7 million twinkling lights along its walking paths for one of eastern Pennsylvania's biggest walk-through holiday displays — its twelfth year in 2025. Alongside the lights are animated holiday scenes, photo spots, fire pits with s'mores, seasonal drinks, nightly princess character performances and Santa photo sessions, plus a dedicated sensory-inclusion hour with lower contrast and volume.
