Rullsand, Public beach in Älvkarleby, Sweden.

Rullsand is a bathing site and campsite at the mouth of the Dalälven in northern Uppland, within the Billudden nature reserve. Its long, shallow sandy beach lies on the Baltic coast, and the site holds 350 pitches, the largest campsite in Uppsala County. A naturum at the entrance has a small exhibition on the reserve and trails leading to the tip of Billudden.

Rullsand grew around a campsite owned by Upplandsstiftelsen and leased to Rullsands Havsbad & Camping AB. With 350 pitches it is the largest campsite in Uppsala County. The sandy beach lies within Billudden Nature Reserve, part of the Uppsala esker, the same ridge that Uppsala Castle stands on.

The beach serves as a social gathering place where locals and visitors spend time swimming and relaxing by the water. You will see families and groups enjoying typical Northern European beach activities throughout the warmer months.

The naturum at the campsite entrance has a small exhibition on the Billudden reserve and its history, and several nature trails start there, one running all the way to the tip of Billudden. The sandy beach is shallow and long, so it shelves gradually. A separate naturist beach nearby is stony and also lies within the reserve.

At this location the Dalälven River meets the Baltic Sea, creating a blend of freshwater and saltwater conditions. This rare combination produces varying swimming conditions that make the beach different from typical coastal areas.
