The harbor is located along the Segara Anakan, one of the largest mangrove-covered estuaries in Java.
The terminal serves as a primary access point to the northern side of Nusakambangan island, a high-security penal facility.
Local boat operators at Sleko often use traditional motorized wooden boats, locally known as 'jukung' or 'perahu penyeberangan'.
The water body surrounding the terminal is characterized by high sediment discharge from local rivers, which contributes to its shallow, silty nature.
Pelabuhan Penyeberangan Sleko functions as a critical local ferry terminal situated along the Segara Anakan lagoon in Cilacap, Central Java. It primarily serves as a transit point for commuters and residents traveling between Cilacap and the nearby island of Nusakambangan. The facility is positioned on a sheltered waterfront area, distinct from open-ocean beaches, providing views of the mangrove-fringed waterways. It acts as an essential gateway for those accessing the coastal regions protected by the barrier island. The site is a hub for small-scale boat transportation services that navigate the shallow estuary environment. It is not a recreational beach, but rather an active industrial and logistical maritime site.

Do not wander into restricted zones near the Nusakambangan ferry boarding areas, as these are monitored for security.
Dress modestly as this is a functional public transit site in a conservative coastal community.
