Obstacles are trees, logs, rocks, and other foliage that is 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.

Each obstacle that is removed can contain anywhere from 0 to 6 Gems.
There are three cycles governing the amount of Gems you receive by removing obstacles in your Home Village and Builder Base. All three cycles are identical to each other, occur concurrently and are independent of each other, meaning that clearing an obstacle advances only one of the below cycles and has no effect on the position of the other two cycles. These cycles repeat as follows: 6, 0, 4, 5, 1, 3, 2, 0, 0, 5, 1, 0, 3, 4, 0, 0, 5, 0, 1, 0.
The first cycle governs the amount of Gems you receive from an obstacle in your Home Village. It advances when you remove an obstacle in the Home Village.
The second cycle governs the amount of Gems you receive from the original obstacles in the Builder Base (i.e. the obstacles that are spawned when you first enter the Builder Base). It advances when you remove such an obstacle in the Builder Base.
The third cycle governs the amount of Gems you receive from spawned obstacles in the Builder Base (i.e. obstacles that spawned sometime after you enter the Builder Base). It advances when you remove such an obstacle in the Builder Base.
On average, each obstacle cleared has 2 Gems. This pattern does not include the 25 Gems held from the Gem Box, or the holiday themed Obstacles like the various Halloween Obstacles (2014-2016) which have Elixir; the X-Mas Trees (2012-2016) have Gold instead.
Vegetation respawns at a rate of one item per eight hours, except if all the spaces in your village are totally filled. Furthermore, an obstacle will only spawn if there is a 1-tile buffer zone between the spaces in which it will spawn and another building or obstacle.
Rocks do not respawn once they are removed.
You can't place buildings on obstacles (unless it is Tall Grass).
Since vegetation respawns, and removing one may have Gems, removing vegetation regularly can be an unlimited (although sometimes slow) source of Gems.
If you accidentally set a Builder to remove an obstacle you can cancel it if the button is tapped before the Builder is finished.
Cancelling the removal of an obstacle will refund you 100% of the resources spent, compared to the 50% refund on all other upgrades.
Your village can have a maximum of 45 obstacles at one time. Gem Box or holiday themed obstacles do not count toward this limit.
Tombstone do not spawn when a troop dies on a building or trap, even if it's destroyed.
Tombstones can spawn in both the Home Village and the Builder Base.
Tombstones in the Builder Base are only visible while you're attacking. They disappear post-fight.
A normal Tombstone is occasionally visible on Loot Carts.
When first entering the Builder Base, several tombstones are present on the base and can be removed after completing the tutorial. They yield 20 Builder Elixir each and do not need Builder Hall 3 or Master Builder to be removed.
The Gem Box is a mysterious box containing 25 gems.
When the Gem Box was added it was quickly deleted due to a few glitches relating to how many Gems it gives. The Gem Box was added back into the game on April 9, 2014, the update that added Clan Wars.
You can only have 1 gem box at any time in a village. Clearing the Gem Box costs 1,000 Elixir. It takes 30 seconds to clear one, and the removal of one will have 25 gems. The gem box is rare, but in the April 2014 update their spawn rate was increased.
Note that all special obstacles (and the Gem Box) ignore the one-tile buffer zone rule that governs where normal vegetation can spawn. They can spawn in any 2x2 empty space within your village, though they tend toward spawning close to the outer edges of the field.
During the Winter 2012 Update, they added a X-Mas Tree that gives 30,000 Gold when cleared, which was then increased to 50,000. On 3 January 2013, Supercell indicated on the forums that people will get to keep their trees even after the winter theme is gone. The 2012 X-Mas Tree appears as a small tree with flashing colorful ornaments.
There's a 2012 edition of X-Mas Tree in the far left edge of the map in Gold Rush mission in Single Player Campaign in the line of trees that are surrounding the map, 2013 edition of X-Mas Tree in Gobbotown mission and the 2014 edition of X-Mas Tree in Fool's Gold mission.
During the Winter 2013 Update, they introduced another X-Mas Tree that gives 75,000 Gold when cleared. The 2013 X-Mas Tree appears as a small tree with golden garlands, a golden spike ball on top, and two skulls at the bottom of the tree.
During the Winter 2014 Update, Supercell introduced an X-Mas tree that not only gives 75,000 Gold when cleared, but randomly spawns wrapped presents worth 5,000 Elixir each when cleared. The 2014 tree is similar looking to the 2012 one, but is adorned with tinsel, candy canes as well as colored ornaments and flashing lights.
During the Winter 2015 Update, they introduced an X-Mas tree that gives 75 000 Gold after cleared. This tree appears like black metal tree with golden chains, spikes and spiky ball on top. There also lays sword next to it. When zoomed, you can see sparks coming out.
During the Winter 2016 Update, they introduced an X-Mas tree that gives 75 000 Gold after cleared. This tree has red ribbons.
There's a special kind of Army Camp in the Goblin Gauntlet mission in the Single Player Campaign that only consists of a camp fire with different surroundings that the one in the Army Camp, which is only 2x2. You can notice this by the other obstacles that are next to the camp fire. You can also drop troops over it since it is considered as an obstacle.

During the 5th anniversary of Clash of Clans (August 2017), Supercell introduced the 5th Anniversary Cake. It costs 25,000 Elixir to destroy, but you get a reward of 75,000 Elixir.
The Spike-y Cactus was released in celebration of Supercell's highly anticipated game, Brawl Stars. It resembles the Brawler Spike.
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 or for free by placing a building on it, and the removal will be instantaneous. The latter method can be done without a Builder Hall level 3.
Removing the Tall Grass with 50 counts towards the Nice and Tidy Achievement and the Gardening Exercise Clan Quest, but placing a building on it for free won't count.
In Village Edit Mode, Tall Grass can be removed using Elixir, but cannot be removed by placing buildings on top of it.
The Old Barbarian Statue will spawn Tall Grasses by its side. The same goes for the Ancient Barbarian Statue decoration. If neither of these is present, any remaining Tall Grass can still spawn beside nearby Tall Grass, but if all the Tall Grass are cleared too, then Tall Grass will not respawn until the Ancient Barbarian Statue is bought.
*Can be removed for free by placing a building on top of it; see above for more details.
**Tall Grass only respawns if at least one of the following is present: other neighboring Tall Grass, the Old Barbarian Statue obstacle, or the Ancient Barbarian Statue decoration.
The Shovel of Obstacles can be used to change the location of an obstacle. Each Shovel of Obstacles has one use, and the affected obstacle can only be moved one time before another is required.
The rainbow effect on the Gem Box might be a reference to the saying "There's a pot of gold at the end of the rainbow." However, in this case, the pot of gold is a pot of gems.
If no gems are purchased, earned through achievements or spent on various purposes, 1623 obstacles (not including gem boxes) are needed to clear to buy the 3rd, 4th and 5th Builder Huts which cost 3500 gems in total, which roughly translates to 528 days (counting from the first obstacle removed and assuming that the village always contain less than 45 obstacles, in order for new obstacles to spawn).
In very early versions of the game, an odd looking stone was able to appear in a newly created village. It became unobtainable soon after the game's release, and only a few players are known to still have it. A few examples of players who still have this stone: (#Y98CJG, #PULPLU, #LLJUOO, #C2VY8G, #LPCL, #UPYJ, #8J88U, #V9CC8).
This stone made a new appearance in the 23rd October 2018 update, in the new Single Player Campaign maps "High Pressure" and "Burning Sensation."
Aside from the Gem Box, the Spike-y Cactus is the only obstacle that gives a different resource than used to remove it.
