Setting Up a Tarp Over Your Tent for Added Protection

Quick answer

• Use a tarp to extend your shelter’s rain and sun protection.
• Choose a tarp size and shape that complements your tent.
• Secure the tarp with stakes and guylines, creating a slope for runoff.
• Ensure airflow between the tarp and tent to prevent condensation.
• Practice your setup before you need it in the field.
• Pack appropriate stakes and cordage for various ground conditions.

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

Before you even think about pitching a tarp over your tent, there are a few critical checks to run through. Get this right, and your camp will be way more comfortable.

• Land manager / legality: Who actually owns this piece of dirt? Is it National Forest, BLM land, a State Park, or private? Each has its own rules. Some areas might have specific restrictions on camping or tarp use. Always check the official website for the land manager. It’s usually easy to find.

• Access/road conditions: Can your rig actually get there? Dirt roads can turn into mud pits in a hurry. Check recent reports if possible. Is it 2WD friendly, or do you need 4WD and good clearance? Don’t get stuck before you even set up camp.

• Fire restrictions + weather + wind: This is huge. Are campfires allowed? What about stoves? Fire restrictions change constantly. Check the weather forecast, paying close attention to wind speed and direction. A strong wind can rip a tarp to shreds or make setup a nightmare.

• Water plan + waste plan (Leave No Trace): Where’s your water source? How will you treat it? And where are you going to stash your waste? Pack it in, pack it out. Always. This applies to everything, including food scraps and toilet paper.

• Safety (wildlife, distance to help, comms): Be aware of local wildlife. Know what’s in the area and how to store food properly. How far is the nearest town or ranger station? Do you have cell service? A satellite messenger or personal locator beacon is smart for remote trips.

Step-by-step (setting up your tarp)

Here’s the workflow. It’s not rocket science, but it takes a little practice.

1. Scout your campsite: Find a relatively flat spot for your tent. Look for natural anchors like sturdy trees.

• Good looks like: A level patch of ground with good drainage and some natural features for rigging.
• Common mistake: Pitching in a low spot that will collect water. Avoid this by looking for slightly higher ground.

2. Pitch your tent first: Set up your tent as you normally would. This establishes your primary shelter and gives you a reference point.

• Good looks like: Your tent is taut and well-staked.
• Common mistake: Relying on the tent’s footprint alone to keep you dry. The tarp adds a crucial layer.

3. Position your tarp: Drape or lay the tarp over your tent. Think about how you want the rain or sun to shed.

• Good looks like: The tarp covers the tent with a good amount of overhang.
• Common mistake: Not leaving enough space between the tarp and the tent. This kills airflow and can lead to condensation.

4. Identify anchor points: Locate trees, rocks, or clear ground spots where you can attach your tarp corners and ridgeline.

• Good looks like: Solid, reliable points that won’t pull out or break.
• Common mistake: Using flimsy saplings or loose rocks. They won’t hold under tension.

5. Rig the ridgeline (if applicable): If your tarp has a ridgeline or you’re using a trekking pole, secure the peak first.

• Good looks like: A taut line that creates a stable peak for your tarp.
• Common mistake: Not making the ridgeline tight enough, leading to sagging.

6. Stake out the corners: Attach your tarp corners to the ground using stakes or tie-offs to trees.

• Good looks like: Corners are pulled taut and the tarp is starting to take shape.
• Common mistake: Driving stakes straight down. Angle them into the ground at about 45 degrees for better holding power.

7. Add guylines: Use cordage to create tension and shape. Angle guylines away from the tarp to pull it taut.

• Good looks like: The tarp is drum-tight, with no flapping or sagging.
• Common mistake: Not using enough guylines or not tensioning them properly. This is where flapping happens.

8. Create a slope for runoff: Ensure the tarp has a consistent angle so water flows away from your tent and campsite.

• Good looks like: Water is clearly channeling to a designated runoff area away from your setup.
• Common mistake: Creating low spots or pockets where water can pool.

9. Check airflow: Make sure there’s a gap between the tent and the tarp. This is vital for ventilation.

• Good looks like: You can feel air moving between the two layers.
• Common mistake: Letting the tarp sag directly onto the tent. This traps moisture.

10. Adjust tension: Go around and check all stakes and guylines. Re-tension as needed, especially if the wind picks up.

• Good looks like: Everything is snug and secure.
• Common mistake: Setting it and forgetting it. Weather changes, and so should your tarp tension.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not checking fire restrictions	Fines, wildfire, jail time. Not fun.	Always check official sources before you leave home.
Ignoring road conditions	Getting stuck, costly tow, missed camping trip.	Research road conditions, check vehicle capability, have a backup plan.
Pitching tarp too close to tent	Condensation buildup, making your tent damp inside.	Leave at least 12 inches of space for airflow.
Not creating a slope for water	Water pooling on the tarp, dripping into your tent or campsite.	Rig the tarp with a consistent downhill angle.
Using inadequate stakes/cordage	Stakes pulling out, guylines snapping, tarp collapsing in wind.	Carry a variety of stakes and strong cordage for different conditions.
Not practicing the setup at home	Frustration and fumbling in the dark or bad weather at your campsite.	Set it up in your backyard first. Get the hang of it.
Over-tensioning the tarp	Ripping seams, tearing fabric, or breaking anchor points.	Tension until taut, but don’t strain the material.
Not considering wind direction	Tarp flapping violently, becoming a sail, or collapsing.	Orient the tarp to minimize wind exposure, or use a lower profile.
Forgetting about ventilation	Excessive condensation, making everything feel damp and clammy.	Ensure a consistent gap between the tarp and tent.
Not considering sun exposure	Overheating inside the tent during the day.	Position the tarp to provide shade where and when you need it.

Decision rules (simple if/then)

• If rain is forecast, then pitch the tarp with a steep slope because you want water to run off quickly.
• If high winds are expected, then lower the tarp profile and use extra guylines because you need to reduce wind resistance.
• If you’re in a sunny, exposed area, then position the tarp to maximize shade during the hottest parts of the day because staying cool is key.
• If you’re camping in bear country, then ensure your tarp setup doesn’t interfere with proper food storage because safety comes first.
• If you have a small tent, then a smaller tarp might suffice, but a larger one offers more versatility because more coverage is usually better.
• If the ground is rocky or hard, then use rocks to anchor guylines instead of stakes because stakes won’t go in.
• If the ground is sandy, then use wider stakes or bury your stakes/rocks because they’ll pull out easily.
• If you’re using a silnylon tarp, then be aware it can stretch when wet, so check tension after rain starts because it might need adjusting.
• If you’re setting up late at night, then have your tent and tarp laid out and ready to go because fumbling in the dark is a recipe for disaster.
• If you have a bathtub-style tent floor, then make sure the tarp’s edge is well above the tent floor to prevent water wicking up because you don’t want any water getting in.
• If you’re in a group camp, then coordinate tarp placement to avoid creating a tripping hazard or blocking access because courtesy matters.

FAQ

Q: Do I really need a tarp over my tent?

A: It’s not always essential, but a tarp significantly boosts your protection from rain and sun, and can help keep your tent cleaner. It adds a lot of comfort.

Q: How big should my tarp be compared to my tent?

A: Generally, you want a tarp that’s at least as wide as your tent and offers good overhang on the sides you want to protect. Think about how the rain or sun hits your campsite.

Q: What kind of stakes should I use?

A: A mix is best. Carry some lightweight aluminum stakes for general use, beefier ones for wind, and maybe some sand stakes if you’re going to the coast.

Q: How do I keep my tent from getting damp inside with a tarp overhead?

A: The key is airflow. Ensure there’s a gap of at least a foot between the tarp and your tent. Don’t let the tarp sag onto the tent.

Q: Can I use trekking poles to set up my tarp?

A: Absolutely. Trekking poles are great for creating a ridgeline or supporting a corner, especially if you don’t have trees. Just make sure they’re sturdy.

Q: What if it starts raining heavily while I’m setting up?

A: Prioritize getting the tent up first. Then, rig the tarp as quickly and efficiently as possible, focusing on a good slope for runoff. You can fine-tune it later.

Q: How do I know if my tarp is tensioned correctly?

A: It should be taut, like a drum. If it’s flapping in the wind, it’s too loose. If you’re straining to pull it tight, it might be too taut.

Q: What if there are no trees to tie my tarp to?

A: Use your trekking poles, rocks, or stakes. You can also create an A-frame or lean-to style setup using just poles and stakes.
