Upon entering Saria, begin your search for the wise man who teaches the Jump spell. He is typically found in one of the houses, similar to the wise man in Rauru. Engage with all the villagers you encounter; some may offer hints about the spell or other secrets. Once you locate the wise man, he will bestow upon you the knowledge of the Jump spell. This spell consumes Magic Points with each use, so be mindful of your Magic Meter. The increased jump height provided by this spell will be immediately noticeable and will open up new pathways on the overworld and within dungeons. Practice using it to get a feel for the extended jump distance. This spell is a game-changer for platforming sections and will be indispensable for reaching higher platforms and avoiding ground-based enemies.
