Musa Point

Musa Point is the northeast edge of the Karamja, located west of Port Sarim. It hosts a dungeon for members, as well as the only spot to cage and harpoon fish for free players outside of the Wilderness.

Entrances
Musa Point can only be entered one way by free players. To enter Musa Point, players need to go to Port Sarim and look for the three sailors, Seaman Lorris, Seaman Thresnor, and Captain Tobias. They will ask if the player wants to go to Karamja. However, it costs 30 coins to sail to Karamja and 30 coins to sail back to Port Sarim.

Members can also enter via the gate to the west from Brimhaven or use the Amulet of Glory to teleport just south of the fishing spots.

When the player lands on Musa Point, they can then get off the boat to walk on the dock and explore the island. There are monsters near the northwestern part of the island around the volcano, so low level players are recommended that they stay away from that part of the island. It is a spot for level 14 scorpions, level 5 snakes, and level 3 monkeys. For lower/almost mid level players, it is a good training spot, as well as a prayer spot, as monkey bones are dropped by the monkeys.

Stores
Musa Point has only one store.

Karamja General Store
Karamja General Store is located west of the boat players arrive on in the f2p part. The general store rarely has anything of value other than fish players sell. Since this part of Karmaja is far away from a bank, players rarely sell anything to this store. However, fishers on the island will sometimes sell their fish to this general store, allowing other players to buy them. Players also sell burnt fish, as it is a faster way of getting rid of them.

Bars
Karamja has a few bars, though only one is available to non-members.

Karamja Wines, Spirits, and Beers
Karamja Wines, Spirits, and Beers is the bar east of the general store. The store is owned by a man named Zambo. Players can purchase beer, Karamja rum, and wine from Zambo.

Quests

 * Pirate's Treasure - In the quest, players need to buy a Karamja rum from Zambo's bar for Redbeard Frank, the pirate. It costs 30gp and can only be transported off the island by being stashed in a crate during Luthas' banana picking game.

Miscellaneous
There are few things players can do on the island.

Fishing spot: This is one of the two places in the free world where players can fish for tuna, lobsters, and swordfish, thus making it the most popular fishing spot in for non-members. It is also a popular chatting place among fishing players

Water Sources: Players can obtain water from a well on the west side of Zambo's bar. However, water is not needed on the island, making this well obsolete.

Luthas' Banana Plantation: Luthas' Banana Plantation is the small hut across from Zambo's bar. Players can collect bananas for Luthas and put them in the box outside his hut. When they've filled the box, Luthas will pay them 30 coins. Luthas is useful if a player forgot their money and cannot go back from the island. There are 33 banana trees in the plantation, each with 5 bananas on each tree. There is also a single respawn air rune north of Lutha's house

Karamja Volcano: Karamja's volcano is in the western part of the island. The volcano contains a dungeon underneath it. There are lesser demons farther west, while the entrance has a few mid-level skeletons. After completing Dragon Slayer, players can go through a hidden wall that leads to the crash site. On the rim of the volcano lie a multitude of dead trees. These trees can be cut for logs, which can subsequently be used to light fires; handy for high-level fishing and cooking at the docks.

Random Events: Karamja seems to have the most Random Events out of any place in RuneScape. Random Events seem to happen more often on the docks, although this could be due to the abundance of players that fish on the docks.
