Serangan Island Coastal and Mangrove Walk

Serangan Island, also called Turtle Island, lies just off the southern coast of Denpasar in Bali, Indonesia, and is joined to the mainland by a causeway. The coastal and mangrove walk follows the shoreline and village lanes from Jl. Tukad Pakerisan toward Pura Sakenan, covering about four to six kilometres round trip in two to three hours. Access is by Grab or Gojek from Sanur, about 25 minutes over the causeway, and visitors should arrange the return ride by app before leaving because pickups can be slow in quieter parts of the island. There is no permit and walking is free, although a small donation applies at Pura Sakenan. The route is flat and at sea level, so elevation gain is negligible and difficulty is low. The surface is a mix of paved village road, sandy tracks, mangrove-edged shoreline and short unpaved sections. Shade is patchy: there are trees in the villages and mangrove stands near the water, but long stretches of shoreline are open, so midday heat can be intense. Landmarks include the mangrove fringe, fishing boats, the island's sea turtle conservation history, and Pura Sakenan, an important sea temple that draws large crowds during its major ceremony. Visitors entering the temple need a sarong and sash and should respect any ceremonies in progress. Small warungs in the island's villages sell water and simple meals, but there are no refuge huts, so walkers should carry water and sun protection. A sensible turn-around is at the temple, or earlier along the shoreline if the heat builds. Views across the water toward Sanur and the Nusa Penida horizon make the walk a quiet, local-feeling alternative to the busier beach districts, with an emphasis on everyday island life rather than developed tourism.
