What Is a Tarp and How Can You Use It?

← Camping Essentials & Setup | Shelter & Sleeping Gear

Quick answer

• A tarp is a large sheet of waterproof material, often reinforced, used for shelter and protection.
• It’s a versatile piece of gear for camping, backpacking, and everyday use.
• Key uses include creating a rainfly, ground cloth, or emergency shelter.
• Choose a tarp based on size, material, and intended purpose.
• Proper setup is crucial for effectiveness and durability.
• Always practice Leave No Trace principles when using a tarp outdoors.

What to check first (do this before you drive out)

Before you even think about pitching a tarp, a little prep goes a long way. This isn’t just about having the right gear; it’s about knowing where you’re going and what to expect.

• Land manager / legality: Who owns this patch of dirt? Is it National Forest, BLM land, a state park, or private? Different agencies have different rules about camping, fires, and where you can set up camp. Always check the official website for the specific area you’re headed to. Ignorance isn’t a great excuse when a ranger shows up.

• Access/road conditions: Can your rig actually get there? A lot of great spots are off the beaten path. Know if you need 2WD, 4WD, high clearance, or if you’re going to be bouncing off rocks. Online forums, ranger stations, and recent trip reports are your friends here. Don’t be the guy who gets their Subaru stuck in a mud pit miles from anywhere.

• Fire restrictions + weather + wind: This is a big one. Fire bans are common, especially in dry seasons. Check the current restrictions before you leave. Weather can change fast, even in summer. Look at the forecast for your specific location, not just the nearest town. And wind? A tarp is basically a sail if you’re not careful. Know what you’re getting into.

• Water plan + waste plan (Leave No Trace): Where are you getting water, and how are you treating it? Don’t assume there’s a spigot. Also, how are you packing out everything you pack in? This includes food scraps, wrappers, and even toilet paper. Tarps can help protect your gear, but they don’t magically make trash disappear.

• Safety (wildlife, distance to help, comms): What kind of critters are in the area? Bears, snakes, ticks? Know how to store food properly and what to do if you encounter wildlife. How far is the nearest town or ranger station? Cell service is often spotty or non-existent. Think about a satellite communicator or letting someone know your detailed itinerary.

Step-by-step (field workflow)

Alright, you’ve done your homework. Now it’s time to put that tarp to work. Here’s how to get it done right.

1. Choose your site: Find a relatively flat, clear spot. Look for natural anchors like sturdy trees or rocks. Avoid setting up directly under dead branches (widowmakers).

• Good looks like: A level patch of ground with good drainage, away from obvious hazards.
• Common mistake: Picking the first flat spot you see without checking overhead hazards or the ground for roots/rocks. Avoid this by doing a quick scan of the immediate area.

2. Clear the ground (optional but recommended): If the ground is rough, clear away sharp rocks, sticks, or pinecones that could puncture your tarp or make sleeping uncomfortable.

• Good looks like: A smooth, clean area where your tarp will rest.
• Common mistake: Not clearing debris, leading to a ripped tarp or a lumpy bed. Take a minute to sweep it clean.

3. Lay out the tarp: Spread the tarp out in your desired configuration. This is where you visualize your shelter.

• Good looks like: The tarp is positioned where you want your shelter to be.
• Common mistake: Rushing this and realizing too late that the orientation isn’t ideal for wind or sun. Take a sec to orient it right.

4. Secure anchor points: Use guy lines and stakes to attach the tarp corners and edges to the ground or trees.

• Good looks like: The tarp is taut, with no sagging, and the stakes are driven in at a 45-degree angle away from the tarp.
• Common mistake: Not pulling the tarp taut enough, leading to pooling water and flapping in the wind. Make it tight.

5. Adjust tension: As you add more anchor points, go back and adjust the tension on each line. You want it snug but not so tight that you’re stressing the material.

• Good looks like: The tarp is evenly tensioned across all points, creating a stable structure.
• Common mistake: Over-tightening one corner and leaving another loose. Work your way around, adjusting as needed.

6. Create an entrance/exit: If your setup allows, define a clear way in and out. This might involve leaving one side partially open or creating a flap.

• Good looks like: Easy access without compromising the shelter’s integrity.
• Common mistake: Making it too hard to get in and out, especially in bad weather. Think about convenience.

7. Reinforce in windy conditions: If it’s windy, add extra guy lines, use rocks to secure edges, or angle the tarp lower to the ground.

• Good looks like: The tarp is stable and not acting like a kite.
• Common mistake: Underestimating wind and not adding enough support. This is how tarps become sails.

8. Check for leaks/drafts: Once set up, do a quick visual inspection. Are there any gaps where rain could get in or drafts? Adjust as needed.

• Good looks like: A solid, enclosed space (depending on your setup).
• Common mistake: Not doing a final check, only to discover a leak when it starts raining. Better to find it now.

9. Manage condensation: Especially in cooler, humid weather, condensation can form inside. Consider ventilation if your setup allows.

• Good looks like: Minimal condensation, keeping you dry.
• Common mistake: Sealing yourself in completely, which guarantees a damp interior. Think about airflow.

10. Pack out everything: When you leave, take down your tarp, clean it if necessary, and pack out all your gear and any trash. Leave the site cleaner than you found it.

• Good looks like: The site is pristine, and your tarp is packed away for its next adventure.
• Common mistake: Leaving behind stakes, bits of cord, or trash. This is a cardinal sin of LNT.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not checking land manager rules	Fines, eviction from campsite, damage to reputation.	Always check the official website for the specific area.
Ignoring road conditions	Getting stuck, vehicle damage, costly recovery, missed trip.	Research road conditions; know your vehicle’s limits.
Setting up under dead trees	Falling branches can cause serious injury or death.	Scout for healthy trees and avoid anything with dead limbs.
Not pulling tarp taut	Water pooling, sagging roof, increased wind resistance, potential collapse.	Use all guy lines and adjust tension until the tarp is drum-tight.
Using wrong stakes/anchors	Stakes pull out, tarp blows away, gear gets soaked or lost.	Use appropriate stakes for the ground type; use rocks or logs for extra weight.
Not considering wind direction	Shelter is drafty, difficult to enter/exit, or blows apart.	Orient the tarp to block prevailing winds; use it as a windbreak.
Overlooking condensation potential	Damp sleeping bag, clammy clothes, uncomfortable night.	Allow for ventilation; consider a tarp with a bathtub floor or a separate ground sheet.
Leaving trash behind	Pollutes the environment, harms wildlife, makes the area look bad.	Pack it in, pack it out. Every single piece.
Not clearing the ground underneath	Punctured tarp, uncomfortable sleeping surface.	Sweep the area for sharp objects before laying out the tarp.
Not having a backup plan for weather	Getting soaked, hypothermia risk, damaged gear.	Always check the forecast and be prepared for sudden changes. Have a more robust shelter option if needed.
Using a tarp as a primary shelter in extreme weather	Inadequate protection from heavy rain, snow, or high winds.	Tarps are great, but know their limitations; use a tent for severe conditions.

Decision rules (simple if/then)

• If it’s raining, then pitch the tarp with a steep angle to shed water quickly because pooling water will eventually leak through.
• If it’s windy, then use extra guy lines and angle the tarp low to the ground because a flatter profile reduces wind resistance.
• If you’re in bear country, then store all food and scented items well away from your sleeping area, preferably in a bear canister or hung from a tree, because you don’t want to attract unwanted visitors.
• If the ground is rocky, then use rocks to weigh down the tarp edges and supplement stakes because stakes might not hold well.
• If you’re using the tarp as a rainfly for a tent, then ensure there’s adequate space between the tarp and tent for ventilation because this prevents condensation buildup.
• If you’re setting up a communal cooking area, then pitch the tarp high and open on the sides because this allows for good airflow and easy access.
• If you’re concerned about bugs, then choose a tarp configuration that minimizes open sides or consider a bug net to hang inside because a tarp alone won’t keep them out.
• If you’re concerned about sun exposure, then orient the tarp to provide shade during the hottest parts of the day because sun can quickly make a campsite uncomfortable.
• If you’re setting up near a water source, then pitch your tarp uphill from it and pack out all waste because you don’t want to contaminate drinking water.
• If you’re unsure about the ground’s stability, then use trees or large rocks as primary anchors for your tarp because they offer more reliable support.
• If you notice your tarp sagging after setup, then go back and tighten the guy lines because a taut tarp performs better.
• If you’re using a silnylon tarp, then be aware that it can stretch when wet and sag, so you may need to readjust tension after it rains because the material’s properties change with moisture.

FAQ

What’s the difference between a tarp and a tent?

A tent is a self-contained shelter with poles and often a built-in floor and bug netting. A tarp is a sheet of waterproof material that requires external support (like trees or poles) and creative pitching to form a shelter. Tarps are generally lighter and more versatile but offer less protection from bugs and the elements without careful setup.

What’s the best material for a camping tarp?

Common materials include nylon (often coated with silicone or polyurethane for waterproofing), polyester, and polyethylene. Silnylon is popular for its strength-to-weight ratio, while poly tarps are often cheaper and very durable. Your choice depends on weight, durability, and cost priorities.

How do I make my tarp waterproof?

Most quality camping tarps are already waterproof due to their material and coatings. For older or less expensive tarps, you might need to reapply a waterproofing spray or seam sealer. Ensure all seams are sealed.

Can I use a tarp as a ground cloth?

Yes, absolutely. A tarp can protect your tent floor from abrasion, moisture, and punctures. Just make sure the tarp is smaller than your tent floor so it doesn’t collect rainwater and funnel it under your tent.

What are guy lines and stakes?

Guy lines are cords attached to the tarp that you use to secure it to anchor points. Stakes are pointed pegs driven into the ground to hold the guy lines. Good quality stakes are essential for a stable setup.

How do I avoid getting wet inside a tarp shelter?

Proper pitching is key. Ensure the tarp is taut with no sagging, and pitch it at an angle to shed water. Also, manage ventilation to reduce condensation, which can feel like a leak.

What’s the minimum number of stakes and guy lines I need?

For a basic A-frame or lean-to setup, you’ll typically need at least four stakes and four guy lines. More complex setups or windy conditions will require more.

Can I use a tarp for emergency shelter?

Definitely. A tarp is a fantastic piece of emergency gear. You can quickly rig a basic shelter to protect yourself from rain or wind if your primary shelter fails or you’re caught out unexpectedly.
