There is a drinking water well here just by the side of the doubletrack road, before it crosses the larger road. The well is a simple cement pipe into the ground with a pipe to lead out excess water and a wooden lid. The water looked pretty clear and tasted nice after filtering. Should be a good water source unless it temporarily dries out during hotter periods.

Sandvik offers a proper camping area, but you need to pay in order to stay here. The reception is only manned 30 minutes in the mornings on weekends. All other times it is self-serviced. It costs 100 SEK or 10 EURO per night, and you can either pay cash in a small post box or via the Swedish Swish app. At the camping there are hot showers and toilets with running water. There is a small playground as well. The main area closest to the road seems to be for RVs, but further back by the playground is an open grass area that is likely intended for tents. There is a recycling center just across the street from the camping. From the camping area there is a trail that connects directly to the beach.

Here is the Brevik parking with a large grass area where you are allowed to camp. There is an outhouse as well as access to drinking water, a fireplace with firewood and some picnic tables. The parking spot is also a prime location for RVs and campervans, so you should expect there to be activity in the evenings, at least during high season. Just opposite the road is a shallow pond. A few hundred meters along the road is Nyviks Brygga with a small beach and additional fireplaces.

Långmaren is an old farm that is now kept preserved in good condition as a historic site that you can visit. Inside the fenced in garden, behind the main house, there is a water tap where you can get drinking water. I don't know where the water comes from! All the buildings of the farm have signs with information of what they were used for.

Nicely located shelter! It is basically in the middle of a large animal grazing area, but the shelter itself is fenced off so the animals can't get there. The area is very large however, so you may not see or encounter them at all. There is a fireplace with provided firewood, and there is a small outhouse behind the shelter. From the shelter you have a nice view of the bay and the water, and if you venture out to the outermost part of the headland the view is even nicer.
