Hume Grove Loop is a dog-friendly, 1.4-mile loop trail in Pena Adobe/Lagoon Valley Park that winds through Jack Hume Grove. The grove is small but beautiful and features towering redwood trees and is a good place for a picnic, with tables provided.
Due to its proximity to I-80, there is some freeway noise from the trail, but it still makes for a nice hike for dog walkers. There are multiple trail offshoots if you’d like to lengthen your hike. Dogs must be leashed on the trail, which is rated easy. Please note there is a parking fee for Pena Adobe/Lagoon Valley Park.
