The present invention relates to a natural gel pack and a manufacturing method thereof which ferment and add lava seawater and Opuntia ficus-indica which are regional specialties of Jeju Island to manufacture a natural gel pack to increase access to the regional specialties and provide an excellent skin soothing effect, mix a hydrophilic natural material with a natural gel pack to dissolve in water after use to be used as a toner or lotion to eliminate waste to protect the environment, and form a functional gel layer in the natural gel pack to effectively absorb nutrients when in use. The manufacturing method comprises: a step of freeze-drying Opuntia ficus-indica in a freeze-dryer and then grinding dehydrated Opuntia ficus-indica to manufacture Opuntia ficus-indica powder； a step of manufacturing Jeju pine mushroom fermentation water； a step of mixing and agitating 20-33 parts by weight of a hydrophilic material, 2-3 parts by weight of the Opuntia ficus-indica powder, 2-3 parts by weight of a glycine max (soy bean) phytoplacenta extract, 1-3 parts by weight of pearl powder, 0.5-1 parts by weight of colloidal gold, and 0.1-0.5 parts by weight of diamond powder based on 100 parts by weight of the Jeju pine mushroom fermentation water to manufacture a hydrophilic gel layer composition； a step of fermenting the hydrophilic gel layer composition； a step of injecting the fermented hydrophilic gel layer composition into a mold and rapidly cooling the hydrophilic gel layer composition at 10°C to manufacture a hydrophilic gel layer having a plurality of grooves formed on a fragment at regular intervals； a step of attaching the functional gel layer to an end surface of the hydrophilic gel layer having a plurality of grooves； and a step of cutting the hydrophilic gel layer with the functional gel layer attached thereto to finish a natural gel pack.본 발명은, 제주 지역특산물인 용암해수와 손바닥 선인장을 숙성하여 첨가한 천연 겔 팩을 제조함으로써 지역특산물의 접근성을 높이는 동시에 우수한 피부 진정효과를 부여할 수 있으며, 천연 겔 팩에 친수성 천연소재를 배합함으로써 사용 후
