What Makes Therma Hot Springs Special?

A Rare Natural Phenomenon

Therma Hot Springs is one of the few places in Greece where visitors can experience geothermal activity up close.

  • The hot spring water originates from deep within the earth, where underground volcanic activity naturally heats the mineral-rich water before it reaches the surface.
  • As the hot water flows through the rocks, it picks up essential minerals like sulfur, calcium, potassium, and magnesium, known for their healing properties.
  • The hot springs pool sits within a rock enclosure, where it gradually blends with the seawater, creating a perfectly warm, therapeutic bathing experience.

💡 Tip: The water closest to the rock enclosure is the hottest, often reaching 50°C (122°F), while areas closer to the open sea are cooler and more comfortable.

The Healing Properties of Therma Hot Springs

For centuries, natural hot springs have been used as healing baths, and Therma is no exception. The high mineral content in the water offers numerous health and wellness benefits:

1. Skin Health & Natural Detox

🛁 The sulfur in the water is known for its cleansing and antibacterial properties, making it beneficial for people with acne, eczema, or dry skin.
💦 The minerals help exfoliate dead skin cells, leaving your skin softer and more hydrated after a soak.
🌿 Many visitors report improved skin texture and a natural glow after regular visits to Therma.

2. Muscle & Joint Pain Relief

💆 The warm temperatures relax tense muscles, making it ideal for those suffering from muscle stiffness or soreness.
🦴 The water is particularly beneficial for people with arthritis or joint pain, as the minerals help reduce inflammation.
🏊 A few minutes of light movement in the pool can improve blood circulation, reducing stress and fatigue.

3. Stress Reduction & Mental Wellness

🧘 The combination of warm water, sea breeze, and natural surroundings creates a deeply calming environment, perfect for relaxation.
😌 Many visitors experience a meditative effect, helping to lower stress levels and anxiety.
🌅 Visiting Therma at sunset can enhance the experience, as the fading daylight over the sea adds an awe-inspiring atmosphere.

💡 Tip: To maximize the health benefits, spend 15-20 minutes soaking, then take a short break in the cooler seawater before re-entering the pool.

🚗 Distance from Psalidi Beach: ~8 km (~15-minute drive)
🚗 Distance from Kardamena: ~35 km (~40-minute drive)

By Bicycle – A Scenic but Challenging Route

🚴 Distance from Kos Town: ~12 km (~45-minute ride)
🚴 Best for: Experienced cyclists who enjoy a challenge

  • The route is beautiful but includes uphill sections, especially near the hot springs.
  • The final descent to the springs is not bike-friendly, so you’ll need to park your bike near the road and walk down.
  • Bring plenty of water, as there are no refreshment stands nearby.

💡 Tip: The best time for cycling is in the early morning or late afternoon, as midday heat can make the journey exhausting.

Hiking Down to Therma Hot Springs

Once you arrive at the parking area, you’ll need to walk down a rocky path to reach the hot springs.

🥾 The descent takes about 10-15 minutes, with some steep and uneven sections.
🪨 The path is gravelly, so wear sturdy shoes—flip-flops are not recommended.
🏖️ At the bottom, you’ll find a hidden cove with the hot spring pool, enclosed by natural rocks.

What to Expect at Therma Hot Springs

Therma Hot Springs offers a unique experience that blends nature, relaxation, and adventure. Before you go, here’s what you should expect:

A Natural Setting with No Luxuries

Unlike commercial hot springs, Therma is completely natural and undeveloped, meaning:

  • There are no entrance fees—the hot springs are free for everyone to enjoy.
  • There are no changing rooms, so visitors change behind rocks or wear swimsuits beforehand.
  • The area is rocky, so water shoes or sandals are recommended for comfort.

💡 Tip: If you need beach essentials, bring them with you—there are no rental services on-site.

The Hot Spring Pools – What’s the Water Like?

🌊 Temperature: The water ranges between 35-50°C (95-122°F), depending on the tides.
🌋 Minerals: The water is rich in sulfur, calcium, and potassium, giving it a slightly cloudy look and a mild sulfur scent.
🏖️ Mixing with the sea: The closer you are to the rocks, the hotter the water; for a more comfortable soak, move toward the open sea where it blends with cooler seawater.

💡 Tip: If the water feels too hot, simply move slightly further into the sea for a gentler temperature.

To make the most of your visit, follow these tips for a perfect experience:

💡 Tip: The best time to visit is either early morning or late afternoon, as midday crowds can make the small pool feel crowded.
