Deer Valley Campsite is a small Department of Conservation campground set among beech forest on grassy flats beside the Lewis River, within the Lewis Pass Scenic Reserve in Canterbury's Springs Junction area.

It lies off State Highway 7, approximately 20 km east of Springs Junction, and is clearly signposted from the road. Note that the access road ends in a tight turning area, so drivers of larger vehicles should approach with caution.

The site offers ten non-powered campsites, a vault toilet, and river water (which should be treated before drinking). Fires are strictly prohibited at all times. Payment is by DOC Campsite Pass or cash via the self-registration stand on site.

The campground sits just three kilometres from the northern terminus of the St James Walkway, making it a convenient base for trampers. Foleys Track to the Libretto Range begins directly opposite the entrance, and Maruia Springs is roughly 10 km away.
