Sycamore Canyon Wilderness Park, recommended by Riverside’s official tourism board and the Press-Enterprise, is a sprawling preserve managed by the city of Riverside but easily accessible from Ontario. The park’s extensive trail system navigates hillsides dotted with wildflowers, rocky outcrops, and ancient sycamores. Community-led restoration projects and educational signage reflect a deep local investment in the land’s health and heritage. The park remains open and welcoming, offering both challenging hikes and peaceful strolls for nature lovers.
