We learned of this place on TripAdvisor; many Tri-Cities folks aren’t aware of its charms or existence! Combo arboretum/garden and park, complete with picnic facilities, rest rooms, delightful splash park for little kids AND a beautiful walk through themed garden “rooms” on paved paths with posted information about each. We thoroughly enjoyed this beautiful and relaxing place, and took loads of photos. Spent several hours enjoying its offerings. And, it’s all free!!
