Sierra Valley Gardens is a mixed-use development being developed by Robinsons Land Corporation in Barangay San Juan, Cainta, Rizal, Philippines. Located on the boundary of Cainta and Taytay, the 18-hectare (44-acre) site was formerly a Mitsubishi Motors Philippines Corporation vehicle production plant until 2015, when it transferred its production site to Santa Rosa, Laguna. Sierra Valley Gardens will have its own Cyber Park technological hub and Robinsons Mall. At an approximate 5 hectares, Robinsons Sierra Valley will be the largest shopping mall in Cainta.
