An endoscopic system includes an insertion portion inserted into a tubular body, a ranging mechanism, an insertion path calculation unit and a presentation unit. The insertion portion includes a distal end and a bending portion defining a driving face. The ranging mechanism acquires distance information on the driving face between an inner wall of the tubular body on a far side and the distal end of the insertion portion while the distal end is placed on a near side in the tubular body. The insertion path calculation unit calculates an insertion path for the distal end of the insertion portion extending from the near side on which the distal end is placed, to the far side, based on the distance information. The presentation unit presents the insertion path for the distal end of the insertion portion extending from the near side to the far side.
