Collecting white berries

White berries spawn in an isolated area in Isafdar, west of Lletya and just north-west of some adamant rocks. They respawn very quickly (about 4-5 seconds) after being picked up, although this is dependent on the population of the world so it's best to collect them on a busy world.

To get to the white berries area, starting out in Lletya, head out through the strange trees due north-west of the city, and cross over the tripwire to the west. Continue on southward past the leaf trap and the Elf Tracker before looping around and heading north and then finally east across a second tripwire to reach the white berries. Consult the map above if you're unsure how to get there. Although the damage is generally insignificant, it's possible you'll take damage from missing the tripwires, so eat food, and drink a dose of Antipoison to negate any damage if necessary.

Once there, just stand over the white berry spawn, clicking it whenever they spawn. After you've collected a full inventory, use the teleport crystal to bank, and repeat. Each trip takes about four to six minutes for a profit of 20,300. Once you've got enough berries, sell them on the Grand Exchange.
