Hammock Tarp Setup: How to Pitch a Rain Fly Step by Step

Quick Answer

Pitch your tarp after your hammock is hung, not before. Run a continuous ridgeline above the hammock at roughly 6 to 8 inches of clearance, center the tarp over the hammock, then tension the corners low and wide so wind-driven rain can't reach you. A diamond pitch is fastest for one person; a hex or rectangular pitch gives more coverage for two or for stormy nights.

A hammock tarp setup fails for one of three reasons: it's pitched too low and touches the hammock, too flat and pools water, or too late — after the rain has already soaked your insulation. Get the order right and the rest is just knots and tension.

This guide walks through the full process in the sequence you'll actually do it at camp, with the checkpoints that catch mistakes before they cost you a dry night. It applies whether you're using a dedicated rain fly or improvising a DIY hammock tarp from a flat shelter.

Before You Pitch: Site and Tree Selection

Pick two trees 12 to 15 feet apart with trunks at least 6 inches in diameter. Look up first: dead branches, called widowmakers, are the single biggest hazard in hammock camping, and a tarp won't protect you from a falling limb. Check the ground for slope and runoff channels, then check the wind direction — you want the tarp's long axis crosswise to the prevailing wind, not parallel to it.

Hang your hammock first at about 15 to 18 inches off the ground with a 30-degree hang angle, then stand back and look at it. Your tarp needs to cover the hammock plus roughly 12 inches of overhang on each end, so confirm the trees give you that span before you commit to a spot.

• Checkpoint: if the hammock sits lower than 12 inches off the ground, raise it before pitching the tarp — you'll need that clearance for the fly.

Run the Ridgeline Above the Hammock

For a tarp ridgeline setup, run a continuous line between the same two trees, tied above your hammock suspension. Aim for 6 to 8 inches of clearance between the ridgeline and the top of your hammock. Too low and the tarp sags into your face all night; too high and rain blown sideways gets underneath. A taut ridgeline also gives the tarp something rigid to pull against, which matters more than the tarp itself in heavy weather.

If you're using a structural ridgeline on the hammock itself, keep the tarp ridgeline separate. Sharing one line means every time you shift your weight, you move your shelter.

• Common mistake: pulling the ridgeline so tight it bends small trees. Use a tree-friendly strap or webbing around the trunk, not bare cord.

Choose Your Tarp Configuration

Hammock tarp configurations come down to coverage versus airflow. The diamond pitch — tarp corners tied to the ridgeline and the two long points staked out — is the fastest to set up and sheds wind well, but it covers the least area. The A-frame pitch, with the tarp ridged along its long axis and both sides staked wide, gives full-length coverage and better side protection, and it's the better choice for two people or for rain that's coming in at an angle.

A hex or cat-cut tarp sits between the two: more coverage than a diamond, less weight and bulk than a full rectangle. If you're using a multi-form shelter, you can pitch it in A-frame or lean-to form depending on whether you need rain coverage, sun shade, or wind blocking that night.

• Checkpoint: stand under the pitched tarp and look up. If you can see open sky directly above your hammock, you've pitched a sunshade, not a rain fly.

Tension the Tarp and Stake It Out

Work corner by corner, alternating sides so the tarp stays centered. Pull each guy line until the fabric is taut but not drum-tight — you want a slight give so gusts don't rip stakes out. Angle your stakes at roughly 45 degrees away from the tarp, and use rocks or logs to weigh down stakes in loose or sandy soil. If you expect wind, lower the tarp's edges closer to the ground and add a second stake point on each side.

The most common failure here is a tarp pitched perfectly flat. Any flat span collects water, sags, and eventually dumps a cold load onto you at 2 a.m. Set one end of the ridgeline slightly lower than the other so water runs off deliberately.

• Common mistake: guy lines pulled straight down into the ground. A shallow angle holds far better and gives the tarp room to flex.

Adjust for Wind, Rain, and Heat

Once the tarp is up, walk around it and look for gaps at the ends. Wind-driven rain rarely falls straight down, so the end openings are where you'll get wet. Pitch one end lower and into the wind, or close it off entirely if your tarp allows. In hot, still conditions, do the opposite: raise the edges and open both ends to keep air moving, because condensation inside a sealed tarp is its own kind of wet.

If you're expecting a serious storm, drop the whole tarp a few inches and widen the stake points. A lower, wider pitch sheds wind better than a tall, narrow one, and it keeps splash-back from reaching your hammock.

• Checkpoint: after 10 minutes of settling, re-tension every line. Fabric and cord stretch, and a tarp that was taut at setup is often flapping by dark.

The Setup Sequence at a Glance

1. 1. Scout trees and hazards: Find two trees 12–15 feet apart, at least 6 inches thick, with no dead limbs overhead. Check wind direction and ground slope. Checkpoint: if you can't find clear overhead space, move — no tarp fixes a widowmaker.
2. 2. Hang the hammock first: Set the hammock 15–18 inches off the ground at a 30-degree hang angle, with room for 12 inches of tarp overhang at each end. Checkpoint: under 12 inches of ground clearance means you'll hit the tarp when you get in.
3. 3. Run the ridgeline: Tie a separate continuous ridgeline between the trees, 6–8 inches above the top of the hammock, using tree straps rather than bare cord. Checkpoint: the ridgeline should be taut enough to pull against without bending the trees.
4. 4. Pick a configuration: Diamond for speed and airflow, A-frame for full coverage and two people, hex or cat-cut for a middle ground. Pitch in lean-to or A-frame form if your shelter converts. Checkpoint: look straight up — open sky above the hammock means you've built a sunshade.
5. 5. Tension corners and stake out: Alternate sides so the tarp stays centered, pull taut with slight give, and angle stakes about 45 degrees away from the tarp. Checkpoint: set one end of the ridgeline lower so water runs off instead of pooling.
6. 6. Re-tension after ten minutes: Walk the perimeter, close the windward end if rain is blowing in, open both ends in hot still weather, and lower the pitch if a storm is coming. Checkpoint: re-tension every line once the fabric has settled — a taut tarp at setup is often flapping by dark.

Gear That Changes the Setup

• Moab All-In-One Shelter Hammock: The MOAB can be used as a hammock, a canopy, an A-frame bivvy, a lean-to shelter, a tent footprint, or a sunshade, and converts between forms. If you're deciding whether to carry a separate rain fly, this is the case where you may not need one — you can pitch it in lean-to or A-frame form for shelter and switch configurations as conditions change.
• Single US States Hammock: Includes a ready-to-hang starter rope kit, two nautical-grade carabiners, and a stuff sack, with triple-lock stitched seams and fast-drying parachute fabric. A hammock that includes its own suspension means one less thing to source before you can focus on the tarp ridgeline and stake-out.
• Ultralight Starter Hammock: Hanging kit and straps are not included; suspension options are sold separately. Budget for suspension before your first trip — a tarp setup is useless if you can't hang the hammock underneath it.
• 360° ThermaQuilt 3-in-1 Blanket, Sleeping Bag & Hammock Underquilt: Wraps completely around a hammock and cinches at the ends, or lays flat as a blanket or sleeping bag, and works with almost any camping hammock. A tarp blocks rain and wind but adds little warmth. This is the layer that keeps you warm underneath, and it works with the hammock you already own.

Pitch the hammock, then the ridgeline, then the tarp — and always finish by re-tensioning. Do those three things in order and you'll stay dry in weather that would send tent campers home.
