Local guide planning is essential because current direction, current strength, and boat traffic all change the route.
Sampalan, also known as Batu Nunggul, is a boat dive on Nusa Penida's harbor side where a sloping reef, barrel sponges, and mixed corals create a colorful east-coast profile. Guides keep the route flexible because the site sits near a busy harbor zone where current, visibility, and boat traffic can all shift the plan.

Key Hazards
Safety Notes
Current direction and strength can change through the dive, and the site sits close to active boat traffic. Plan entries, ascents, and pickups with a guide who is actively managing the route for the day.
Access Restrictions
Boat access only. This is a route-planned dive, not a casual harbor drift, so guides need to be comfortable with the day’s current and traffic.
Legal Notes
Follow local boat-traffic rules and guide instructions on entries, ascents, and pickups.
