How to become a tree climber: skills, gear, training and credentials
Tree climbers do the work most people would never try: pruning and taking down trees from the inside, tied in with ropes, with a saw in hand. It is a real skill that takes years to master. Here is how people get there, safely.

What a tree climber does
Pruning
Removing dead, weak or crossing limbs, raising the canopy over roofs and roads, and thinning or reducing a crown to good standards.
Removals in pieces
Taking a tree down from the top when there is no room to fell it. The climber cuts pieces that the ground crew lowers on ropes.
Rigging
Setting blocks and lines so heavy wood comes down under control. Good rigging protects the house, the lawn and the crew.
Storm work
Working on broken, hung-up and twisted trees after storms. This is the most dangerous work in the trade and needs the most experience.
Cabling and bracing
Installing support systems in trees that are worth saving, often with an arborist's plan.
The usual path to climbing
Nobody should learn to climb alone. The safe path is slow, step by step, with a trained climber watching.
-
Step 1
Ground first
Most climbers spend months or more on the ground, learning knots, rigging, saws and how a climber thinks.
-
Step 2
Learn to climb with a trainer
Start low and slow, with a trained climber watching. Learn to tie in, ascend, move through the canopy and descend safely.
-
Step 3
Learn aerial rescue
Before working alone up high, the crew must know how to get an injured climber down. Practice it often.
-
Step 4
Small pruning jobs
Build skill and stamina on simple pruning before moving to removals.
-
Step 5
Removals and rigging
Move up to piece-down removals and heavier rigging only when your trainer says you are ready.
If you have not worked on a crew yet, start with our groundworker guide.
Skills climbers need
Knots and hitches
Friction hitches, the bowline, the running bowline, the clove hitch and more. Climbers trust their lives to these, so practice daily.
Climbing systems
Moving rope and stationary rope systems, how to set an anchor and how to choose a tie-in point you trust.
Tree reading
Seeing decay, cracks, dead wood and weak unions before you trust a limb. This links climbing to arborist knowledge.
Saw work aloft
Running a top-handle saw safely while tied in, with two points of attachment when cutting, as your training requires.
Calm communication
Clear calls to the ground crew, every time, before anything drops.
Climbing gear
A climber's kit usually includes a tree climbing saddle, a climbing rope and lanyard, friction hitch cords or mechanical devices, carabiners rated for life support, a helmet, eye and ear protection, gloves, boots and a top-handle saw for work aloft. Gear must be rated for tree climbing, inspected before each use and retired when worn.
See our plain guides to climbing gear, rigging gear, chainsaws and protective gear.
Safety and aerial rescue
In the US, the main safety standard for tree work is ANSI Z133. Good companies train to it and hold a short safety talk before each job. Three habits matter most for climbers.
- Inspect your gear and your tie-in point every time. Look at the tree before you trust it.
- Make sure someone on the ground is trained in aerial rescue, and practice it as a crew.
- Stay away from power lines unless you are a qualified line-clearance worker.

Credentials for climbers
You do not need a credential to start climbing, but it helps you move up and it helps your company show customers who is in their trees. The ISA offers the Certified Tree Worker/Climber Specialist for climbers and the ISA Certified Arborist for broader tree knowledge. The TCIA offers safety training and the Certified Treecare Safety Professional (CTSP). Rules, fees and exams change, so check the official sites. Our certifications page explains each one.
Pay
The US Bureau of Labor Statistics lists a median hourly wage of $24.50 for tree trimmers and pruners, for May 2025. That group includes climbers and other tree workers.
Source: BLS Occupational Outlook Handbook, Grounds Maintenance Workers, data for May 2025, checked October 2026.
Climbers with years of experience, storm skills and credentials can earn more than the median, but pay varies by region and company. Check the BLS for your area and ask employers how they set pay.
For owners: growing your own climbers
Good climbers are hard to find, so many owners train their own. Give promising groundworkers a written path, pair them with a patient climber, pay for training and credentials, and practice aerial rescue as a crew. Then tell your customers who is in their trees. It builds trust.
Plan the cost with the hiring cost calculator and the workers comp estimator, and read the hiring and crews guide. A trained climber needs a full schedule: see how our services help you answer every call, check pricing, or get a free audit.
Common questions
How long does it take to become a tree climber?
It depends on the company, your training and your skill. Many climbers spend a season or more on the ground first, then climb under a trainer for months before working on removals.
Do I need to be very strong?
You need good fitness, grip and stamina, but technique matters more than raw strength. Good systems and good habits save energy all day.
Am I too old to start climbing?
There is no fixed age. People start at different ages. What matters is fitness, careful habits and good training. Talk to an experienced climber or employer about your situation.
What climbing gear do I need to buy?
It depends on the employer. Many supply ropes and rigging, and some supply saddles and helmets. Ask before you buy, and only use gear rated for tree climbing and inspected often.
Is climbing more dangerous than other tree jobs?
Climbing has added risks from falls and from cutting aloft. Following the ANSI Z133 safety standard, inspecting gear and practicing aerial rescue lower the risk.
Can I climb near power lines?
Not unless you are a trained and qualified line-clearance worker. Work near energized lines has special rules. Everyone else must stay well clear and call the utility.
Which credential should a climber get?
The ISA Certified Tree Worker/Climber Specialist is made for climbers. Many climbers later earn ISA Certified Arborist too. See our certifications page.
How much do tree climbers make?
The BLS lists a median hourly wage of $24.50 for tree trimmers and pruners in May 2025. Experienced climbers can earn more, but pay varies by region and company. Check the BLS for your area.
Is a bucket truck the same job as climbing?
Not exactly. Aerial lift work uses a bucket truck instead of ropes. Many climbers do both. Lift operators need their own training on the machine.
What comes after climbing?
Many climbers become crew leaders, arborists, estimators or trainers. Some start their own tree company.
