A backyard course is the best kind of crazy golf: no queue, no closing time, and the windmill can be whatever you have in the shed. The good news is that you do not need artificial turf, power tools or a weekend of digging. Most great home courses are built from a lawn, a few cups, some edging and a lot of imagination. This guide walks through planning, building and packing up a course that is fun to play and kind to your grass.
Step 1: Walk the yard like a golf architect
Before you buy or build anything, take a ball and a putter (or a broom handle) and walk the space. Roll the ball in a few directions and notice what it does. Lawns are rarely flat, and those little slopes are free design features. A gentle tilt toward the fence can become a hole where players have to aim uphill of the cup. A dip near the patio can become a "valley" hole.
While you walk, look for natural boundaries: paths, flower beds, the edge of the patio, a tree trunk. Anything solid that a ball can bounce off is a potential wall. Also note the no-go zones. Keep holes away from ponds, steps, glass doors, vegetable beds and anywhere a ball could roll into the street. If young children will play, keep the whole course where an adult can see every hole from one spot.
Sketch a quick map on paper. Mark the spots where you could fit a tee and a cup at least two to three metres apart. Most home courses fit six or nine holes comfortably; you do not need eighteen to have a great afternoon.
Step 2: Choose your cups
The cup is the heart of every hole, and you have three practical options:
- Sunken cups. Cut a small plug of turf with a bulb planter, drop in a plastic cup or a short length of plastic pipe, and set it slightly below the grass line. Keep the plug in a shaded tray and water it so you can replace it afterwards.
- Surface targets. A tipped-over plastic cup, a small bucket on its side, or a flat ring you must stop the ball inside. These leave no marks at all and suit rented yards.
- Portable putting cups. Many garden and golf shops sell ramp-style cups that sit on the ground. They are handy, though balls sometimes roll back out, so decide whether "touching the back of the cup" counts.
A standard golf hole is 4.25 inches (108 mm) wide. You do not need to match it; a slightly bigger target makes a home course friendlier for kids and first-timers.
Step 3: Build borders and fairways
Borders are what turn a lawn into a mini golf hole. They keep the ball in play and create bank shots. Good options include lengths of timber laid on their side, pool noodles pinned down with tent pegs, garden hose laid in curves, bricks or pavers set end to end, and flexible plastic lawn edging. Pool noodles are especially good for families because they are soft and they can be cut with a bread knife to any length.
Keep fairways at least 60 cm (about two feet) wide so players can swing without clipping the edges. Narrow sections are fine for a challenge, but only for a short stretch. If your lawn is long, mow it short on the day and consider mowing the fairways a little shorter than the surrounding grass. The difference makes the ball roll faster down the "green" and visually marks the hole.
| Material | Bounce | Kid-friendly | Leaves marks? |
|---|---|---|---|
| Pool noodles + tent pegs | Soft, low | Very | Small peg holes only |
| Timber boards | Firm, predictable | Watch for splinters | Can yellow grass if left for days |
| Garden hose | Low, a bit random | Yes | No |
| Bricks or pavers | Hard, lively | Mind toes | Can flatten grass |
| Plastic lawn edging | Medium | Yes | Only if pushed into soil |
Step 4: Add one feature per hole
The quickest way to make a course feel "crazy" is to give every hole a single personality. Hole one might be a straight warm-up. Hole two runs through a tunnel made from a cardboard box. Hole three asks you to bank off a board. Hole four has a ramp made from a plank and a paving slab. One strong idea per hole beats five small ones scattered around; it is easier to explain, and players remember it.
Our guide to DIY mini golf obstacles has plenty of ideas, and designing mini golf holes explains how to set par and flow so the course feels fair.
Step 5: Signs, scorecards and the tee
Mark each tee with a small square of doormat, a flat stone or a piece of chalk on the patio. Number the holes with plant labels, paper plates on sticks or painted rocks. A hand-drawn scorecard on a clipboard adds to the event feel. Write the par for each hole and any special rule, such as "ball in the flower bed: drop at the border, add one stroke."
Think about the route between holes too. The end of one hole should be close to the start of the next so players are not crossing through someone else's shot.
Step 6: Protecting the lawn
Grass is tougher than it looks, but a few habits help. Do not leave boards, mats or tarps on the lawn for more than a day in warm weather; blocked light turns grass yellow. Move tees around between sessions so the same patch is not trampled every time. Water turf plugs you removed and put them back the same evening. If the ground is soft after rain, wait a day; heavy foot traffic on wet soil compacts it.
Packing-up checklist
- Count the balls and putters back into one box.
- Pull all tent pegs and fill the cup holes with their turf plugs.
- Lift boards, mats and signs so the grass gets light.
- Sweep through the flower beds for stray balls.
- Photograph the layout so you can rebuild it quickly next time.
Frequently asked questions
How much space do I need for a backyard mini golf course?
A small yard of around 8 by 8 metres can fit four to six short holes if you let them cross back and forth. Holes can be as short as two metres; creativity matters more than length.
Can I build a course on a rented lawn?
Yes. Use surface targets instead of sunken cups, and choose borders such as pool noodles and hoses that do not require digging. Remove everything within a day so the grass stays green.
What kind of balls work best on grass?
Standard golf balls roll well on short grass. Brightly coloured balls are easier to find, and soft foam or practice balls are a good choice if small children or windows are nearby.
How do I make the course harder for adults?
Narrow a fairway, add a bank shot, move the cup behind a slope, or set a lower par. You can also require players to use their weaker hand on one hole.
Play safe: swing low near people, pets and windows, and follow any posted course rules.
