How to find and enter Crystal Cave

Direct answer · 01

Crystal Cave is in Moonlit Pines. From the farm, take the northeast path into the forest and look near Fiona's House. A large boulder blocks the entrance: use a Copper Pickaxe to break it. Bring an Iron Pickaxe as well, because the Rose Quartz and Moon Crystal nodes inside require it.
