Hollyford Valley is a valley in Fiordland, New Zealand, in the southwest of the South Island. It is named for the Hollyford River, which runs north-north-west along its length from the Southern Alps to the Tasman Sea. Beech forest dominates both the slopes and the bottom of the valley.
Historically very remote, there is still only one road into the valley, Milford Road, which approaches the valley from the south from Te Anau, but turns towards Homer's Saddle into Milford Sound long before reaching the coast. The turnoff site, a former roadworkers camp, sports a small museum and is a starting point for a number of tramping routes, with about 2,000 people per year exploring the Hollyford Valley backcountry.
