巣栗渓谷 — photo spot in Takeshikamihoniri, Ueda, Nagano 386-0507, Japan

巣栗渓谷 (Sukuri Valley) offers layered river-cut cliffs, seasonal greenery, and misty ravine depth that suit moody landscape frames. Best in spring (fresh leaves) and autumn (foliage), with early mornings for soft light and fewer hikers. Access is by car in Ueda; trail sections are uneven—wear grippy shoes and expect limited facilities.more
