Celebrate Spring and Earth Week at Riverbend Environmental Education Center with a special Earth Day Open House and Tree Planting - and the grand reopening and relaunch of their unique Aquaponics Greenhouse and the Snider Barn. Starting on Thursday, April 21, 2022, Riverbend will open the Snider Barn again to school groups after being closed due to the pandemic. Riverbend will also relaunch the Aquaponics Greenhouse, where aquaculture (raising fish in a controlled environment) and hydroponics (growing plants without soil) come together in this unique hand-on laboratory. On Saturday, April 23, 2022, Riverbend will host an Earth Day Open House and Tree Planting from 10:00am to Noon. The family-friendly event is $25 per family and includes a guided tour, a visit to the Aquaponics Greenhouse, time with Riverbend’s Animal Ambassadors, a hike up Valley View Trail and the tree planting itself. Riverbend also is open for spring and summer for exploration of the trails, bird watching, and celebrating nature and the great outdoors. More than 5,000 native species of plants are located on the preserve, and 107 species of birds have been spotted on the grounds. Riverbend's 30-acre nature preserve is located at 1950 Spring Mill Rd., in Gladwyne, PA. The outdoor preserve, trails and outdoor amenities are open 365 days a year from dawn to dusk daily.
