The Apricot Valley is currently accessible only from the Dry Riverbed. It contains a broken pump, similar to the one near the Twin Houses, as well as multiple water sources inside the main house. Additionally, the house contains an unending supply of stored apricots, which can be used to fully recover Daphne's wellness.
In the barn-like structure on the hill, Daphne can find the athletic shorts which, in game, gives her the kneepads. Completing the Noises from the Cellar quest rewards Daphne with the Restorative Tonic recipe.
