California dreaming is a great dive site attracting a large number of divers. Most divers come to see the very colourful corals, the large number of gorgonian fans, the large number of different underwater marine life, and like other dive sites in Lembeh, the muck diving.

The dive site is fairly deep, going down to 40 metres although many divers tend to stay in the shallower parts of the dive to see the marine life and to explore the area for macro life. At around 14 metres, there is a plateau that is teeming with marine life and it is here that muck divers can also investigate the nooks and crannies and try to spot some of the critters residents in the area. Unlike other muck diving sites, the visibility here tends to be very good and ranges from around 5 metres to highs of around 25 metres. The coral is spectacular with many colourful patches of coral garden, a number of red gorgonians, and also some orange tree corals. This also makes it a slightly different type of muck dive site.

Divers will be able to spot many turtles, tuna fish, and mackerel. The site is very good for underwater macro photography as along with these, divers can spot many smaller types of marine life. The dive site, in particular, is well known for being home to many manta shrimps, orangutan crabs, mandarin fish, banded ells, banded sea snakes, blue-ringed octopus, mimic octopus, hair frogfish, giant frogfish, and lionfish.
