Nai Wong Nuea (ในวงเหนือ) is a subdistrict in the inland Nai Wong area of La-Un, Ranong. The Fine Arts Department describes Nai Wong as a mountain-enclosed landscape with limestone outcrops, foothills and valley ground shared across the northern and southern tambons.
A June 2026 Community Development Department report identifies the agricultural market at Ban Nai Wong in Village 2 during quality-control work for the locality's durian and mangosteen products. This is a specific market and farming context within Nai Wong Nuea. The tambon remains distinct from Nai Wong Tai and from individual caves or orchards in the wider valley.
