We are bringing the nature center to you! Each season’s pop up has a different theme. Come talk with a naturalist about the park, explore some natural objects, ask questions and try out biology-themed activities. This is a walk-up event providing a 20 to 30 minute experience. Stay to play or hike in the park! The Nature On Wheels vehicle will host this event. We will be meeting at Rock Creek Regional Park by the Lake Needwood playground (picnic area #3).
