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 (Lewis Pass Highway), roughly 20 km east of Springs Junction, and is clearly signposted from the road. Note that the access road ends with tight turns, so larger vehicles should approach with caution.

The site offers ten non-powered campsites and is well-placed for exploring the surrounding area — it sits about three kilometres east of the northern terminus of the St James Walkway, and Foleys Track to the Libretto Range begins directly opposite the entrance.

Facilities include a vault toilet and river water. A permanent fire ban is in place. Payment is accepted via DOC Campsite Pass or cash at the self-registration stand on site.
