Details of leveling up woodcutting skills in Runescape
Logs can be cut and sold for 148 runescape gold each. Normal trees are found virtually everywhere around Runescape but without the use of a Seers Headband only give one set of Logs per tree. The forest west of Lumbridge, the Grand Exchange, and the area east of Varrock are all convenient places to gather normal logs because of the number of trees and proximity to a bank. Members may also do the normal Evil Tree which may be cut for noted logs, Birds nests, and other prizes. Regular logs also come from dead trees, dying trees, and evergreen trees. As you increase your woodcutting skill, the time it takes you to chop down a tree decreases, increasing your profit.
Oak logs are in demand for the Construction skill and sell for 82 coins each. Oak trees can be found in many places, most notably just east of the Draynor Village bank, east and west of Varrock, directly south of the Seers Village bank, and south of the southern Falador gate. Members can also do oak Evil Trees for Woodcutting-related prizes not only about the Runescape Gold.
Willow logs sell for 28 coins each, and can be cut in many locations. However, only a few are actually used by players. They are the best trees to cut for training, and one can make a reasonable profit from selling them. The best locations to cut willow logs include:
South of Drainer Village This is probably the spot of choice for free players and members alike. It is literally seconds from a bank, which means profit and XP are both maximized. Words of warning about training are here, though, as there are many players who train at this spot. Still, this is probably the best location to cut willow logs (at least for less experienced players)
South of Seers Village flax fields There are 4 or so willow trees next to the water. This plantation is rarely crowded, and the bank is still pretty close by.
North of Seers Village bank There are around 4 trees to the west of the maple trees. The bank is still very close.
West of the Barbarian Outpost There is a deposit box nearby, and the area can be easily reached using a Games necklace.
As noted before, there are many more locations of willow trees, most of which are located near water. So as long as you careful find, and then you will get runescape gold as much as possible.
