Erstaviksbadet, Sand beach in Nacka Municipality, Sweden.

Erstaviksbadet is a beach at Erstaviken in Nacka Municipality, about 120 metres of sand below a grassy slope, with rock formations on both sides. A small café sits above the beach and a boat club stands beside it. The beach belongs to Erstavik and is maintained by Nacka Municipality.

The beach emerged as Saltsjobaden developed into a residential town in the 1800s and the shoreline became publicly accessible. A natural coastline gradually transformed into a popular swimming destination for the expanding local community.

The beach serves as a gathering place where local families spend their summer days swimming and relaxing together. People come here to enjoy outdoor time in a setting that has long been part of the region's leisure traditions.

The Saltsjöbanan stop named Erstaviksbadet is about 1.2 km as the crow flies from the beach, so the walk is longer than the name suggests. The beach lies 2 km east of Erstavik manor and 3 km west of Solsidan, and can be reached on foot from both the Tattby nature reserve and the Nacka reserve.
