Västra Götaland County

Sweden

Start in the shallows on the north east side and move south east were you will find a drop-off. At 18-26 meters there are hang-overs. The walls are often covered with marine life. Look for the large colourful sea anemones. Keep an eye on your depth.



Kattholmen

As soon as you are out of the small bay it drops of quickly. First a couple of shelves at 6 and 14 metres, and then a drop off. Look for lobster in between the boulders. Flat fishes hide in the sandy spots and great anemones and soft corals on the wall. Macro photography in the shallow with kelp.

Only by boat. But there is an old molo which makes for a small protected "harbour" where one can tie up the boat safely. 

Svarteberget

The bay features gently sloping sand/silt bottom. sometimes you see wolf fish here. Then follow the cliffs to the south where there are rocks and crevices. Best marine life between 8 and 20 metres.



Vitbukt

Dive along the shore on the Norwegian side of the fjord is best. A few meters west of the bridge there is an natural threshold which tends to increase the tidal current. boulders from the bridge construction is a good spot for marine life which hide in the crevices. This is also one of the few places you can actually cross a country border while diving..legally. Although the diving on the Swedish side is not so good.



Svinesund

It drops off quickly, but not as an vertical wall. There are boulders, shelves and canyons, pending where you are diving. Lots of seanemones, huge white sea urchins and some reef fish like species of Labridae (Ballan wrasse and Cuckoo Wrasse). Small-spotted catshark (Scyliorhinus canicula) has been observed at this site twice on night dives.



Bleksund

This small cluster of rocks in open ocean offers multiple dive sites. South/south-west side starting with boulders changing to sand bottom between 16 and 22 meters. Good fishlife here. On the line between the southern most rocks there is a steep wall with corals and anemones. North and east the bottom slopes gentle, covered with boulders and rocks. Less plants and softcorals here, but good fish-life.

This dive site is easy to navigate, often with good visibility but prone to surface currents and waves.

Kostersten is a cluster of 4-5 rocks with a small "lagoon" in between. The largest rocks is facing west. 

Kostersten

Big boulders, overhangs (almost caverns) down to 24 metres. The sandy slope. Shallower and more interesting if you swim from the middle of the bay and north (around the skerries). Swim south for deeper water, walls and larger fish on the sand bottom.



Vattenholmen - West

One of the best sites in the area, but also difficult access due to sea conditions. Flat ocean makes a great divesite. Good kelp = lots of fish. Crevices with lobster. Sandbottom with both anemones and other bottom dwellers, like rays.

An reef starting at 5 meters. Falling bottom lesser to the east, but quicker deeper to the south.

Ullvillarna

These two small islands in the Oslofjord offer good marine life. Start and end the dvies in both directions (diving westwards is best) thru the small sound between the islands. 

Start/end your dives in the narrow sound between Søndre Missingen (north) and Ovnskjær (south). Good place to ancher the boat on a small bay at the east end of the sound. 

Søndre Missingen

This small lake has very clear springwater. Trees fallen into the water make a great background for UW images. Most of all the blue water can make you fel lost in space if you venture out in the middle of the lake. Great for ice diving as well.



Klaretjern

In the start varied terrain with lots of boulders. Halfway up the island you will find vertical walls with ledges, before the terrains starts to slope. At the noth end of the island it gets shallower and the terrain more varied again. Either follow the slope at 10-12 depth and end dive in open water, or follow the bottom countour (north-east) and end the dive in shallow water at the north end. Look for lobster and crabs among the boulders, large labridea along the wall and nudibranchia on kelp in the shallows.

Start diving at the southern most point of the islanc, and dive the westside.
