This zoo feels intentionally designed to take advantage of Oregon's seasonal weather. It's a shady stroll in the summer time where the pines, maples and other trees of the West hills offer respite for families while exploring the zoo's facilities... This visit we went at the beginning of winter. Expecting at least a chill and a drizzle we wore our fun rain boots and impermeable jackets. The kids could splash in puddles and most viewing areas had some level of cover to park the stroller as to keep it from getting too wet in-between exhibits. The best part of this visit, and it may have been blind luck, but many of the animals were front and center. My daughter was inches away from the Lion on the other side of the glass because they were resting in a dry den with a comfy hay bed. Nora the polar bear was out exploring her new home which was next to the well hearted elephant enclosure. Our timing was perfect as we made a keeper's presentation for some primates and a photo opportunity with the elephants! There are times posted at many of the exhibits declaring when a keeper will come to feed, speak, present, etc... on this cool day coffee was available at the aviary Cafe... Which has elevated views into the neighboring aviary... But I'd recommend strolling through the aviary as you can get quite up close to some beautiful uncommon birds. It's fun to end one's visit with the short train ride that's accompanied with views and a verbal presentation by the conductor. They'll explain that the zoo has its own post mark- so anyone visiting from out of town... Or anyone who enjoys sending themselves post cards as a family keepsake as we do... Then this is your opportunity to get that rare postmark on your postcard! Beware that the gift shop may be out of any given supplies (especially stamps) so I'd recommend loading up your cards with your snack bag or other zoo trip supplies. We embraced the weather, saw some lively animals, made some cute memories with the children and otherwise left feeling very pleased with the visit. A few things of note: tickets are ONLY purchased online. Parking is plentiful but paid by app or kiosk. The zoo is built into the hills so you'll be walking up/down slopes. They do rent strollers or other wheeled assistance. There is a lovely park nearby that home to the breathtaking (free)rose gardens and the (paid entry)Japanese gardens. Enjoy your trip and hope you get to see many of the beautiful animals that the Oregon zoo cares for!
