Obstacles are trees, logs and rocks that are randomly placed in your village. You start with about 40 obstacles around your village. You can remove them if you have an available Builder and a small amount of Gold or Elixir. Gold is used to remove rocks and Elixir to remove vegetation.

During the 5th anniversary of Clash of Clans (August 2017), Supercell introduced the 5th Anniversary Cake. It costs 25,000 Elisir to destroy, but you get a reward of 75 000 Elisir.

You must have a Builder Hall level 3 in order to remove obstacles in the Builder Base.
Obstacles in the Builder Base respawn in a similar fashion to Obstacles in the Home Village. While trees and other types of vegetation will respawn over time if the obstacle limit isn't reached, rocks and stones will not respawn.
Many obstacles are common to both the Home Village and Builder Base.
The Tall Grass is the only Builder Base Obstacle that doesn't require a free Master Builder to remove, and will never yield Gems. You can either remove it with 50 Elixir or for free by placing a building on it, and the removal will be instantaneous.
Removing the Tall Grass with 50 Elixir counts towards the Nice and Tidy Achievement and the Gardening Exercise Clan Quest, but placing a building on it for free won't count.
The Old Barbarian Statue will spawn Tall Grasses by its side. The same goes for the Ancient Barbarian Statue decoration. You get 3 gems when you destroy it.
