Pantai Undi is a serene coastal gem nestled in the village of Yensum within West Papua's Masni District. Spanning approximately 600 meters of pristine shoreline, this beach offers a tranquil escape with its expansive sandy vistas and relatively undiscovered atmosphere[1]. While visitor reviews highlight its natural beauty, some note inconsistencies in maintenance, balancing its raw charm with a need for improved infrastructure[5]. The beach's remote location contributes to its unspoiled allure, making it ideal for travelers seeking solitude amidst Indonesia's coastal splendor.
The vibe leans toward peaceful seclusion, with visitors praising its scenic sunsets and calm waters. However, amenities remain basic, emphasizing its off-the-beaten-path character. Recent reviews suggest it's gaining attention locally, particularly for budget-friendly visits, with minimal fees for parking and beach access[5].
