Sulcata tortoises (also known as African spurred tortoises) are one of the most rewarding reptiles to keep, but they are also one of the largest. These incredible reptiles can live well over 70 years and grow to more than 100 pounds, making proper outdoor housing essential for their long-term health and happiness.

If you're planning to keep a Sulcata tortoise outdoors, this guide covers everything you need—from fencing and shelters to heating, feeding, and daily care.

Why Sulcata Tortoises Thrive Outdoors

Sulcata tortoises are native to the hot, dry regions of northern Africa. They thrive in warm climates with access to natural sunlight, plenty of space to roam, and room to graze. Outdoor enclosures provide the exercise, UVB exposure, and enrichment they need to stay healthy.

Benefits of outdoor housing include:

• Natural sunlight for Vitamin D3 production

• More room for exercise

• Better grazing opportunities

• Reduced stress

• More natural behaviors such as digging and basking

1. A Large Secure Outdoor Enclosure

The first thing every Sulcata needs is space.

These tortoises grow incredibly fast and become extremely strong. Small pens are quickly outgrown.

A good enclosure should include:

• Plenty of grazing space

• Secure fencing

• Safe plants

• Multiple shaded areas

• Easy access to clean water

Many keepers start with an 8x8 foot enclosure for juveniles, but adults often require several hundred square feet or even a large fenced yard.

2. Strong Tortoise-Proof Fencing

Sulcatas are expert escape artists.

They push.

They dig.

They climb surprisingly well.

Your fencing should:

• Be at least 18–24 inches underground

• Stand 18–24 inches above ground for young tortoises

• Be 24–36 inches or taller for adults

• Prevent visibility through the fence to reduce pacing

Popular fencing materials include:

• Wood privacy fencing

• Concrete blocks

• Landscape timbers

• Composite fencing

Many say avoid chain-link fencing because many Sulcatas continually try to walk through it, but a visual barrier on the bottom 2 ft of the fence will deter that. Truth be told, I still see mine pace a solid wall just as much as one they can see through. At the bottom of my fence I have a combination of cross ties and tin for sight barriers as well as about 30-inch sections of rebar every 10 inches to strengthen the fence and to prevent tortoises from digging out.

3. A Warm, Dry Tortoise House

Even in warm climates, Sulcatas need a weatherproof shelter.

Their house should protect them from:

• Rain

• Cold temperatures

• Wind

• Humidity

Many keepers build insulated tortoise sheds or convert small storage sheds.

Inside the shelter provide:

• Dry flooring

• Straw or orchard grass bedding (if appropriate for your climate)

• Good ventilation

• Safe heating equipment

4. Reliable Heating for Cool Weather

Sulcata tortoises cannot tolerate prolonged cold temperatures.

Most keepers use:

• Heat lamps

• Ceramic heat emitters

• Oil-filled heaters (inside insulated sheds)

• Pig blanket heaters designed for livestock

Always connect heating equipment to a quality thermostat to maintain safe temperatures and avoid overheating.

Recommended temperatures:

• Shelter: 80–90°F

• Basking area: 95–100°F

• Night temperatures: ideally above 70°F for younger tortoises

5. A Thermostat

One of the most important pieces of equipment is a thermostat.

A thermostat:

• Prevents overheating

• Saves electricity

• Keeps temperatures stable

• Helps protect heating equipment

Without one, temperatures inside a tortoise house can quickly become dangerous.

6. Digital Thermometers and Temperature Gun

Never guess temperatures.

Use:

• Digital thermometer with probes

• Infrared temperature gun

• Hygrometer to monitor humidity

Checking temperatures regularly ensures your tortoise stays comfortable throughout the day.

7. Natural Sunlight

Sunlight provides essential UVB rays that help Sulcata tortoises produce Vitamin D3, allowing them to properly use calcium.

Outdoor tortoises usually receive all the UVB they need naturally.

Provide:

• Sunny basking areas

• Partial shade

• Trees or shade structures

The tortoise should always be able to choose between sun and shade.

8. Fresh Water Every Day

Although Sulcatas come from dry environments, they still require constant access to clean drinking water.

Choose a shallow water dish that:

• Is easy to enter

• Is easy to clean

• Cannot tip over

Replace water daily.

Many keepers also soak young Sulcatas several times each week to support hydration.

9. Proper Diet

A healthy Sulcata diet consists mostly of grasses and weeds.

Excellent foods include:

• Bermuda grass

• Orchard grass

• Timothy hay

• Bahia grass

• Dandelion

• Plantain weeds

• Clover (in moderation)

• Hibiscus leaves and flowers

• Mulberry leaves

• Mazuri Tortoise Chow

Avoid excessive fruit and high-protein foods.

A high-fiber diet promotes healthy shell growth and proper digestion.

10. Calcium Supplement

Calcium supports:

• Strong shell growth

• Healthy bones

• Proper muscle function

Young tortoises often benefit from lightly dusting food with calcium powder several times per week.

Adult tortoises grazing outdoors generally require less supplementation but should still have access to calcium sources as recommended for their diet and environment.

11. Cuttlebone

Many keepers leave a cuttlebone inside the enclosure.

Benefits include:

• Extra calcium

• Natural beak trimming

• Safe chewing enrichment

Many Sulcatas will nibble on it whenever they feel the need.

12. Safe Grazing Plants

Planting edible vegetation can reduce feeding costs while providing enrichment.

Popular choices include:

• Bermuda grass

• Prickly pear cactus (spineless varieties)

• Hibiscus

• Mulberry

• Grape leaves

• Mallow

• Dandelions

• Chickweed

• Plantain weeds

Avoid toxic ornamental plants, and always verify plant safety before adding them to the enclosure.

13. Shade Areas

Shade is just as important as sunshine.

Use:

• Trees

• Shade cloth

• Bushes

• Wooden shelters

• Large rocks

Sulcatas regulate their body temperature by moving between sunny and shaded areas.

14. Digging Areas

Digging is a natural instinct.

Provide areas with natural soil where your tortoise can:

• Dig burrows

• Cool down

• Explore naturally

Avoid substrates that stay constantly wet.

15. Daily Health Checks

Spend a few minutes each day checking your tortoise.

Look for:

• Bright eyes

• Clear nose

• Normal appetite

• Strong walking

• Healthy shell

• Clean vent

• No injuries

Early detection can prevent many serious health problems.

16. Predator Protection

Young Sulcatas are vulnerable to predators.

Potential threats include:

• Dogs

• Coyotes

• Hawks

• Raccoons

• Foxes

Use secure fencing and consider covered enclosures for hatchlings and small juveniles.

17. Seasonal Planning

Depending on your climate, you may need to adjust care throughout the year.

During cooler months:

• Increase shelter heating

• Monitor temperatures more frequently

• Keep the shelter dry

• Limit exposure to cold, wet weather

In warmer months:

• Ensure plenty of shade

• Refresh water often

• Watch for signs of overheating

Planning ahead helps keep your tortoise comfortable year-round.

Frequently Asked Questions

Can Sulcata tortoises live outside year- round?

In warm climates where temperatures remain suitable and a heated shelter is available, many Sulcata tortoises can live outdoors year-round. In colder regions, they often need additional protection or indoor housing during winter.

How big should an outdoor enclosure be?

Bigger is always better. Adult Sulcatas benefit from several hundred square feet or more to roam, graze, and exercise.

Do outdoor Sulcatas still need UVB lights?

If they receive regular, unfiltered natural sunlight, supplemental UVB lighting is generally unnecessary.

What temperature is too cold?

Young Sulcatas are especially sensitive to cold. Prolonged exposure to temperatures below about 70°F can lead to health issues, while adults also need protection from extended cold and damp conditions. Here in Georgia, I find Sulcatas to be much hardier, and don't give extra heat till temps drop below 55. As long as they have time to bask on sunny days with ambient temps above 75, they are able to warm their core temperature, so a brief cool down to 55 isn't going to harm them, it actually helps mimic seasonal temperature swings they would find in their natural range . Once temps drop below 50 I provide heat, Which Ive gone over earlier in this post.

Final Thoughts

Keeping a Sulcata tortoise outdoors is one of the best ways to provide a healthy, enriching life for these gentle giants. A spacious enclosure, sturdy fencing, a warm insulated shelter, reliable heating, fresh water, a high-fiber diet, and regular health checks are the foundation of excellent care.

With proper planning and the right equipment, your Sulcata tortoise can thrive outdoors for decades, rewarding you with fascinating behaviors and becoming a lifelong companion. Investing in quality housing, safe heating, nutritious food, and durable enclosure supplies from the start will make caring for your tortoise easier and help ensure a long, healthy life.
