Waterproof Tarps: The Ultimate Camping Shelter Guide
Master the art of weatherproofing your campsite. From lightweight backpacking tarps to heavy-duty basecamp shelters, discover how the right tarp can transform your outdoor experience.
EXPLORE THE GUIDEWhy a Waterproof Tarp is Essential: A reliable tarp is one of the most versatile pieces of camping gear you can own. It serves as an emergency shelter, a rain fly, a ground cloth, a windbreak, and even a sunshade. Unlike a tent, a tarp offers flexible configuration options that adapt to changing weather conditions and campsite layouts.
Why Waterproof Tarps Are a Camping Game-Changer
Every seasoned camper knows that weather can turn on a dime. A sudden downpour or an unexpected gust of wind can ruin an otherwise perfect trip if you are not prepared. This is where a waterproof tarp becomes invaluable. Unlike the rain fly that comes with your tent, a standalone tarp gives you complete control over your shelter setup. You can pitch it high for ventilation on warm rainy days, or stake it low to block driving wind and rain.
For those who practice Leave No Trace principles, a tarp is an excellent choice because it allows you to create a shelter without disturbing the ground beneath you. When you are wild camping or using BLM land, a tarp setup is often more appropriate than a heavy tent. Furthermore, if you are camping in a tent in the rain, adding a tarp over your tent can provide an extra layer of protection against moisture and extend the life of your tent's waterproof coating.
But not all tarps are created equal. The material, size, and construction of your tarp will determine how well it performs in different conditions. This guide will walk you through everything you need to know to choose the right waterproof tarp for your adventures, whether you are a first-time camper or a seasoned backpacker.
Tarp Materials Explained: Which One Is Right for You?
The material of your tarp directly impacts its weight, durability, and waterproof rating. Here is a breakdown of the most common options:
Polyethylene (PE) Tarps
These are the ubiquitous blue or green tarps you see at hardware stores. They are incredibly durable, fully waterproof, and very affordable. However, they are also heavy and bulky, making them best suited for car camping and basecamp setups where weight is not a concern. Their reinforced grommets make them easy to tie down, and they can withstand significant abuse.
Polyester and Nylon Tarps
These are the preferred choice for backpackers and backpacking trips. They are lightweight, pack down small, and offer excellent strength-to-weight ratios. Nylon is slightly more durable and stretchy, while polyester is more resistant to UV degradation and does not stretch as much when wet. Both can be treated with silicone or polyurethane coatings to achieve high waterproof ratings.
Vinyl Tarps
Vinyl tarps are heavy-duty and extremely waterproof, often used for industrial purposes. They are very heavy and not practical for camping, but they can be useful for long-term campground setups where the tarp will remain in place for extended periods.
Canvas Tarps
Canvas tarps are breathable and extremely durable, but they are also very heavy and require regular maintenance to maintain their water resistance. They are a traditional choice for wall tents and bell tents, but not ideal for portable camping.
| Material | Weight | Durability | Waterproofing | Best For |
|---|---|---|---|---|
| Polyethylene (PE) | Heavy | High | Excellent | Car camping, basecamp, utility use |
| Polyester | Light | Medium-High | Very Good | Backpacking, ultralight shelters |
| Nylon | Light | High | Very Good | Backpacking, hammock camping |
| Vinyl | Very Heavy | Very High | Excellent | Long-term setups, industrial use |
| Canvas | Very Heavy | Very High | Good (with treatment) | Wall tents, permanent camps |
Choosing the Right Size and Shape
The size of your tarp determines how much coverage you can create. A good rule of thumb is to choose a tarp that is at least as large as your tent's footprint, but ideally larger so you can create an awning or vestibule area.
Common Tarp Sizes
- 8x10 feet: Ideal for solo campers or couples. This size provides enough coverage for a small sleeping area and a bit of gear storage.
- 10x10 feet: A versatile size for small groups. It can be configured as an A-frame shelter or a lean-to.
- 10x12 feet: Great for larger groups or for creating a spacious communal area. This size works well as a dining fly or a group shelter.
- 12x12 feet and larger: Best for basecamp setups, family camping, or camping with kids where you need ample covered space.
When selecting a size, consider the number of people and the amount of gear you need to protect. Also think about the climate: in wetter environments, a larger tarp provides more dry space for cooking and socializing. If you are camping in the rain, a larger tarp is almost always a better choice.
Shapes: Square vs. Rectangular
Square tarps are the most versatile because they can be pitched in many different configurations, including the popular diamond fly and the A-frame. Rectangular tarps are excellent for creating long, narrow shelters or for use as a simple lean-to. For most campers, a square tarp offers the greatest flexibility.
Key Features to Look For in a Waterproof Tarp
Not all tarps are designed for camping. Here are the features that matter most when you are using a tarp for outdoor shelter:
Waterproof Rating
Look for a tarp with a hydrostatic head rating of at least 1,500mm, though 2,000mm or higher is better for prolonged exposure to rain. This rating indicates how much water pressure the fabric can withstand before leaking.
Reinforced Tie-Out Points
The grommets or loops where you attach your guy lines are the weakest points of any tarp. Look for reinforced corners and edges with multiple tie-out points. Some high-end tarps feature webbing loops along the entire edge, which provide more pitching options and greater strength.
Ripstop Fabric
Ripstop nylon or polyester is woven with a grid pattern that prevents tears from spreading. This is a valuable feature for any tarp that will be exposed to rough conditions.
UV Resistance
If you plan to use your tarp as a sunshade, UV resistance is crucial. Prolonged exposure to sunlight can degrade synthetic fabrics, causing them to become brittle and lose their waterproof properties. Look for tarps with a UV-resistant coating or those made from solution-dyed fabrics.
Seam Sealing
Even the most waterproof fabric can leak through the seams. Check whether the tarp has taped or sealed seams. If not, you may need to seal them yourself with a seam sealer product.
How to Pitch a Waterproof Tarp for Maximum Protection
The beauty of a tarp is its versatility. Here are some common configurations and when to use them:
The A-Frame
This is the classic tarp shelter. Pitch it like a simple tent by tying the ridge line between two trees and staking out the corners. It provides excellent rain protection and good ventilation. For tips on pitching in wet conditions, see our guide on how to set up a tent in the rain.
The Lean-To
This configuration is ideal for windy conditions. Stake one edge of the tarp to the ground and angle the other edge up towards the wind. This creates a windbreak and a reflective surface that can bounce heat from a fire back towards you.
The Diamond Fly
This is a lightweight and minimalist shelter for solo campers. Pitch the tarp diagonally, using trekking poles or trees to create a low-profile shelter that sheds wind and rain effectively.
The Dining Fly
For group camping, pitch a large tarp high above the cooking area to create a covered communal space. This is invaluable for camping with kids or during extended rainy periods.
When pitching your tarp, always ensure that you have a way to tension the guy lines. Shock cord or tensioners can help keep the tarp taut even when the wind picks up. If you are camping in a tent in the rain, you can use a tarp as an additional rain fly to protect your tent's entrance and create a dry vestibule area.
Waterproof Tarp Tiers: Finding the Right Level for Your Needs
To help you make an informed decision, we have categorized waterproof tarps into three quality tiers based on their features, materials, and intended use. This classification helps you match your tarp to your camping style without getting bogged down in technical specifications.
| Tier | Best For | Typical Features | Trade-offs |
|---|---|---|---|
| Entry-Level | Occasional campers, car camping, utility use | Polyethylene material, basic grommets, standard waterproofing | Heavier, bulkier, less packable |
| Mid-Range | Regular campers, backpackers, weekend warriors | Ripstop nylon or polyester, reinforced tie-outs, taped seams, lighter weight | Higher cost than entry-level, requires more care |
| Premium | Serious backpackers, thru-hikers, extreme conditions | Ultralight silicone-impregnated fabrics, multiple tie-out points, exceptional waterproofing, compact packed size | Highest cost, requires meticulous handling |
When choosing your tier, consider how often you camp and the conditions you typically encounter. If you are a casual camper who mostly does car camping, an entry-level tarp is perfectly adequate. If you are a backpacker who values every ounce, investing in a mid-range or premium tarp will pay off in comfort and performance. For those who camp in extreme conditions, such as winter camping or camping in heavy rain, a premium tarp is a worthwhile investment.
Pros and Cons of Using a Tarp Shelter
Advantages
- Extremely versatile; can be configured in many ways
- Lightweight and packable compared to a tent
- Excellent ventilation, reducing condensation
- Can be used as a ground cloth, windbreak, or sunshade
- Generally more affordable than a tent of similar coverage
- Allows you to camp in areas where tents are not permitted
Disadvantages
- Requires skill and practice to pitch effectively
- Less protection from insects and crawling creatures
- No built-in floor, so you need a ground sheet
- Can be noisy in strong winds if not pitched taut
- Not as warm as a tent in cold conditions
- Setup can be challenging without trees or trekking poles
Despite these drawbacks, many experienced campers prefer a tarp over a tent for its flexibility and connection to the outdoors. If you are camping with a dog, a tarp can provide a shaded area for your pet to relax while keeping them out of the sun. For first-time campers, a tarp is an excellent backup shelter to have in case of unexpected weather.
Frequently Asked Questions About Waterproof Tarps
What is the best material for a waterproof camping tarp?
The best material depends on your needs. For backpacking, lightweight ripstop nylon or polyester treated with silicone or polyurethane is ideal. For car camping and basecamp use, heavy-duty polyethylene tarps offer excellent durability and waterproofing at a lower cost.
How do I waterproof a tarp that is not fully waterproof?
You can apply a waterproofing spray or a silicone-based sealant to the fabric. For seams, use a seam sealer. However, if your tarp is not designed for camping, it may be more practical to purchase a purpose-built waterproof tarp.
Can I use a tarp as a tent footprint?
Yes, a tarp can be used as a ground cloth under your tent to protect the tent floor from abrasion and moisture. Ensure the tarp is slightly smaller than your tent's footprint so that it does not collect rainwater.
How do I pitch a tarp without trees?
You can use trekking poles, dedicated tarp poles, or even sticks and rocks to create anchor points. In open areas, you can use a single pole to create a pyramid-style shelter. For more tips, see our guide on camping in a tent in the rain.
Is a tarp better than a tent?
Neither is universally better. A tarp is more versatile and lighter, but a tent offers more protection from insects and ground moisture. Many campers carry both: a tent for sleeping and a tarp for a communal area or extra rain protection.
How often should I replace my waterproof tarp?
With proper care, a quality tarp can last for many seasons. Inspect it regularly for tears, worn areas, and degradation of the waterproof coating. If the tarp no longer sheds water effectively or has significant damage, it is time to replace it.
