Located on the western edge of Memorial Park, the Houston Arboretum & Nature Center offers an escape from the hustle and bustle of city life and the opportunity to experience the natural world. This 155-acre non-profit urban nature sanctuary provides education about the natural environment to Houstonians of all ages. It plays a vital role in protecting native plants and animals in the heart of the city where development threatens their survival. Visitors can explore nature by walking on trails (totaling 5 miles) free of charge. The Nature Center building includes the Discovery Room with interactive exhibits and activities and the Nature Shop filled with items for nature lovers of all ages.
