Most trampoline advice assumes a flat, dry, sheltered lawn. Plenty of gardens in County Monaghan are none of those things. The county is drumlin country: small steep hills, damp hollows between them and clay underneath. This guide takes the three conditions that shape the choice here, slope, wet ground and wind, and sets out what each one means for the type, size and position of a trampoline.
The local facts come from Monaghan County Council and Met Éireann, and the rules on siting come from BERG's own manual. We name and link each source. Where nobody has published a figure, we do not make one up.
Drumlins are the low, rounded hills left behind by the ice. Monaghan County Council's Landscape Character Assessment uses the old phrase for how they look on a map: "basket of eggs" topography. For a garden, it means the site very often falls one way or another, and the lawn you see from the back door is bigger than the level ground you can use.
BERG's manual leaves no room on this point. It says to make sure the trampoline "is installed on level ground", with the legs "equal in height" and resting "firmly on the ground". BERG gives no slope that it considers acceptable, so neither do we.
Three practical things follow.
The drumlins are made of glacial till, and the same Landscape Character Assessment is blunt about how it behaves: "The till is very dense and water cannot percolate through very easily." It goes on: "the land is wet and difficult to drain". The hollows between the hills are described as "poorly drained".
For a trampoline on legs, slow drainage is a nuisance, not a barrier. Nothing is dug. Keep it out of the lowest, wettest corner so the legs rest on firm ground, and that is the main of it.
For an InGround or FlatGround trampoline, drainage is the whole question, because both sit over a hollow in the lawn. BERG's manual requires "adequate drainage" to take rain water away, and tells the person fitting it to check that a high ground-water level will not leave water collecting underneath.
Whether a given spot meets that requirement cannot be read off a map or judged from a photo. It depends on the slope, the soil at that exact place and where the water runs. It is the job of the installer, landscaper or builder to assess it on site, and a good one will tell you if the answer is no. We sell in-ground trampolines all over Ireland and are glad to sell them here, but on Monaghan ground we would always have someone look before you order. We do not install, and we do not publish hole sizes or drainage methods: see who installs a trampoline in Monaghan.
A house on the side or the top of a drumlin gets the wind. How hard it can blow inland was shown on 24 January 2025, when Storm Éowyn brought red wind warnings to every county. At Met Éireann's station at Ballyhaise in County Cavan a gust of 115 km/h was recorded that morning, as the Anglo-Celt reported from Met Éireann's provisional figures. We have not found a published gust for a station inside County Monaghan, so we do not quote one.
BERG's manual is brief on the subject: "Strong winds and gusts can displace the trampoline." It recommends anchoring. Its storm advice adds three steps:
Both kits fit any make of trampoline standing on grass. Ground anchors do not hold in a patio, concrete or gravel. Check them after every named storm and tighten or re-seat any that have lifted. Ordered with a trampoline they travel free; on their own, delivery is €11.99.
Four galvanised steel corkscrew anchors with four webbing straps and buckle tensioners. The straps go over the frame and can be tightened again when the ground softens.
Adjustable, and easier to take out again.
€55was €59.99
Eight galvanised ground stakes, 30cm long, one over the frame at each leg. Eight covers most round trampolines up to 14ft.
More fixing points. Not adjustable.
€55was €59.99
Type matters too. A FlatGround or InGround trampoline sits at or close to lawn level, so the wind has far less to catch than on a trampoline on legs. A net catches wind on any of them. BERG publishes no wind speed at which a trampoline is safe or unsafe, and we will not invent one: when a storm is forecast, anchor it and take the net down.
Clones has the long weather record in the county. On Met Éireann's figures it averaged about 960 mm of rain a year between 1978 and 2007, with some rain on roughly 218 days of the year. For comparison, Met Éireann's climate averages for 1991 to 2020 put the national figure at about 1,288 mm. So Monaghan is not one of the wettest parts of the country.
The trouble here is less how much rain falls than how slowly the clay lets it go. Some rain on about three days in five, onto ground that holds water, is why the drainage question in section 2 deserves more attention in Monaghan than the rainfall total would suggest.
Four kinds of garden cover most of what we are asked about. The models under each are starting points taken from our catalogue, with current prices. Every card links to that model on TrampolinesIreland.com, where orders are placed.
Typical of a town garden, or of a sloping site with one flat area near the house. Go by the level ground and BERG's 2 metre clearance. Round is the shape with the small sizes: 200cm and 270cm across. A trampoline on legs comes with a net and asks nothing of your drainage. Above-ground models start at €449. See round trampolines.

Where the level ground is a strip, a circle wastes it. An oval (BERG's Grand) or a rectangle (Ultim) gives more jumping length for the same width. Remember that the 2 metre clearance applies on every side.

The slope comes first: a level area has to be made, whatever you buy. If a landscaper or builder is going to be moving earth anyway, that is the moment to ask them whether an InGround would suit the spot and how it would drain. InGround models start at €339 and are sold with or without a net. If the answer on drainage is no, the same level area will take a trampoline on legs.

Space is not the limit here. Wind usually is, and so is the view. A FlatGround sits flush with the grass, catches far less wind than a trampoline on legs and leaves the outlook as it was. It starts at €699, and on this ground it stands or falls on the installer's view of the drainage. If you stay above ground on an open site, plan to anchor it. With room to spare, the large ovals and rectangles, and the Pro Bouncer, come into play.

If you would like a second opinion on any of this, send us two or three photos of the garden and rough measurements of the level area. Tell us about the slope, any corner that stays wet, and how exposed the site is. We will suggest a type, a shape and a size, and give you a delivered price. It costs nothing and commits you to nothing.
Book a free garden consultation, or ring the Monaghan line on 047 67255. One limit, stated plainly: we can advise on fit, size and type from photos, but we cannot judge drainage from them. For an in-ground model that still needs an installer on site. Delivery is covered on the delivery page.
Not on the slope itself. BERG's manual says the trampoline must be installed on level ground, with the legs equal in height and resting firmly on the ground. On a sloping site that means either using a part of the garden that is already level or having a level area made first. BERG does not publish a slope it will tolerate, so we do not quote one.
BERG asks for at least 2 metres clear between the trampoline and trees, fences and any other obstacles, and at least 7 metres clear overhead, measured from the ground. Measure the level part of the garden with those margins in mind, not the whole lawn.
Only if the ground at that spot drains well enough. BERG requires adequate drainage for an in-ground trampoline and a check of the ground-water level. Monaghan County Council's Landscape Character Assessment describes the county's glacial till as very dense, and the land as wet and difficult to drain. An installer has to judge your own ground. A trampoline on legs avoids the question.
BERG's advice is to move it to a more sheltered spot if you can, to secure the legs to the lawn with an anchor set, and, before a heavy storm, to take off the safety net and the padding. Check the anchors again once the storm has passed. We sell two anchor kits at €55 each: four corkscrew anchors with adjustable straps, or eight ground stakes.
One set into the ground. A FlatGround or InGround trampoline sits at or near lawn level, so there is far less for the wind to catch than on a trampoline standing on legs. A safety net catches wind on any type.
Clones averaged about 960 mm a year between 1978 and 2007, on Met Éireann's figures, which is below the national average of about 1,288 mm for 1991 to 2020. For a trampoline the total matters less than the soil: dense clay holds water, so think about where it lies before choosing the spot, and above all before choosing an in-ground model.
Send a few photos and the measurements of the level area. We will recommend a type, shape and size for your ground and give you a delivered price. It is free and there is no obligation.
