The 41-year-old actress took to Instagram where she shared the pictures with her 13-year-old son.
"Wilderness buddy," Witherspoon captioned a selfie with his son, who looked quite touristy with their caps and camera on.
The "Big Little Lies" actress shared another photograph after the mother-son duo indulged in kayaking.
"River kayaking adventure! #WeSurvived #Canada #StayWILD," she wrote alongside the upside-down picture, perhaps looking tired after their tryst.
According to ET Online, the trip seems to be an annual outing for the actress and her son.
"Let's do this! Into the wilderness we go... #StayWILD #HikingTrip," she captioned a pic then.
