Nature & Wildlife

Although Thailand occupies only 0.4% of the Earth's surface, it is estimated to host 10% of all animal and plant species in the world. This is due to its unique location: Thailand is the bridge between the Indo-Burmese and the Malay-Sunda bioregions — two of the most species-rich areas on Earth.

Forest Types

• Tropical Rainforest: In the south and southwest (Khao Sok, Khao Lak), evergreen, with trees up to 60 m high, extreme species diversity. Home to tigers, leopards, Malayan bears, and the largest flower in the world — the Rafflesia (up to 80 cm in diameter, smells like carrion).
• Monsoon Forest: In central and northern Thailand, loses its leaves in the dry season. Teak, Dipterocarpus, and bamboo forests.
• Highland Forest: In the northern mountains (over 1,000 m), cooler, with oaks, chestnuts, and rhododendrons. The Doi Inthanon (2,565 m) is Thailand's highest mountain.
• Mangroves: Along the coasts, especially in Phang Nga and Trang. Important protection against tsunamis and nursery for fish.

Wildlife Highlights

Thailand is home to over 300 mammal species, 1,000 bird species, and 350 reptile species. Some of the most remarkable include:

• Indochinese Tiger: Fewer than 200 specimens in the wild, mainly in the Huai Kha Khaeng Wildlife Sanctuary.
• Asian Elephant: About 3,000–4,000 in captivity, only ~3,000 still living wild.
• Gibbons: White-handed gibbon and lar gibbon — their song penetrates the rainforest in the early morning.
• Hornbills: Up to 13 species, including the spectacular great hornbill with its distinctive casque.
• Whale Sharks: In the waters around the Similan Islands and Richelieu Rock (October–May).

Thailand has 155 national parks and over 1,200 protected areas, covering about 18% of the land area. The entrance fee for foreigners has been uniformly 300 Baht (about 8 €) since 2024 — half for children.

1. Khao Sok (Surat Thani)

The oldest evergreen rainforest in the world — 160 million years old, older than the Amazon. The Cheow Lan Lake (Ratchaprapha Dam) with its dramatic limestone cliffs rising from emerald green water is one of Thailand's most spectacular landscapes. Overnight stays in floating bungalows on the lake. Here you can find the Rafflesia and, with luck, wild elephants, gibbons, langurs, and over 300 bird species.

2. Erawan (Kanchanaburi)

Famous for its seven-tiered waterfall, whose turquoise pools invite you to swim (yes, you can go in!). The top tier is said to resemble the three-headed elephant Erawan from Hindu mythology. Easily accessible as a day trip from Bangkok (3 hours). Best during the rainy season (June–October) when the waterfall carries the most water.

3. Doi Inthanon (Chiang Mai)

Thailand's highest mountain (2,565 m) with misty forests, waterfalls, and two royal pagodas at the summit. In the morning, it can drop below 5°C here — bring warm clothing! The Hmong and Karen villages on the way to the summit offer insight into the life of the hill tribes. Excellent for bird watching.

4. Mu Ko Similan (Phang Nga)

The Similan Islands are among the best diving areas in the world: Crystal clear water (30 m visibility), healthy coral reefs, manta rays, whale sharks. The park is only open from October to May (monsoon!). There are simple accommodations on two of the nine islands — reserve early. Snorkelers will enjoy Ko Miang and Ko Similan.

5. Khao Yai (Nakhon Ratchasima)

Thailand's oldest national park (1962), UNESCO World Heritage, and only 3 hours from Bangkok. Over 2,000 km² of monsoon forest with elephants, gibbons, hornbills, pythons, and even some tigers. The Haew Narok Waterfall (150 m) is the highest in the park. Night hikes (Night Safari) offer the chance to see nocturnal animals — sambar deer, civet cats, with luck a bear.

Thailand's 2,600 km coastline (Gulf of Thailand and Andaman Sea) is home to over 300 coral species and more than 1,500 fish species. The reefs range from world-class to severely damaged — where you dive and snorkel makes a huge difference.

Best Diving and Snorkeling Areas

• Similan Islands (Andaman Sea): The ultimate. Healthy hard corals, manta rays, whale sharks at Richelieu Rock. October–May.
• Surin Islands (Andaman Sea): Even more untouched than Similan. Fewer visitors, excellent snorkeling directly from the beach.
• Koh Tao (Gulf of Thailand): The cheapest diving training in the world — PADI Open Water from 9,000 Baht (250 €). Good reefs for beginners, but partially affected by mass tourism.
• Koh Lipe (Andaman Sea): Coral reefs right off the beach. Perfect for snorkeling, even without a boat.

Coral Bleaching & Environmental Issues

The reality is worrying: Over 50% of the corals in the Gulf of Thailand are damaged by warming, overfishing, and tourism. The Andaman Sea is in better condition, but coral bleaching is also increasing here. Thailand has responded: Maya Bay (Koh Phi Phi) was closed to tourists from 2018–2022 and has since reopened with strict visitor limits. Similar measures apply to other sensitive areas.

The elephant is Thailand's national animal and deeply rooted in culture and history. Just 100 years ago, there were over 100,000 elephants in Thailand — today there are fewer than 7,000 (about half wild, half in captivity). The topic of "elephant tourism" is emotional and complex.

What You Should NOT Do

• Elephant Riding: The howdah (seat on the back) causes long-term spinal damage. The "taming" (Phajaan) of young animals is a brutal process that breaks the animal's spirit. Most reputable animal welfare organizations categorically reject elephant riding.
• Elephant Shows: Elephants that paint, play football, or perform tricks have been trained through coercion. Avoid these shows.
• Trekking Camps: Boycott camps that use chains and hooks (ankus).

Ethical Alternatives

There are now numerous ethical sanctuaries in Thailand that house rescued elephants and responsibly involve tourists:

• Elephant Nature Park (Chiang Mai): Founded by the legendary animal rights activist Lek Chailert. No rides, no shows — instead, you observe elephants in their social group, feed them, and walk with them to the river. The model for all ethical camps. Day visit from 2,500 Baht (69 €).
• Elephant Jungle Sanctuary (Chiang Mai): Smaller groups, similar concept. Several locations, also in Pattaya and Phuket.
• Boon Lott's Elephant Sanctuary (Sukhothai): Very personal, maximum 6 guests, multi-day stays. One of the best places to truly get to know elephants.
• Wildlife Friends Foundation Thailand (Phetchaburi): Not only elephants but also bears, macaques, and other rescued animals.

How to Recognize a Good Camp

• No rides, no chains, no hooks
• Elephants live in social groups with space
• Transparent funding (where does your money go?)
• Small groups (max. 10–15 visitors per elephant)
• Good reviews on independent platforms

Thailand has a tropical monsoon climate with three seasons — but weather conditions vary greatly between regions:

The Three Seasons

• Hot Dry Season (March–May): The hottest phase, especially in central and northern Thailand. Temperatures of 35–40°C are normal, in Bangkok it feels even hotter due to humidity. April is the hottest month — and the month of the Songkran Water Festival (April 13–15), where everyone drenches each other with water.
• Rainy Season / Monsoon (June–October): The southwest monsoon brings the rainy season. "Rain" in Thailand rarely means continuous rain like in Germany: Typically, there are short, heavy showers (1–2 hours) in the afternoon, after which it clears up. Nature is lush green, temples are empty, prices are low — for many, the most beautiful travel time.
• Cool Dry Season (November–February): The most popular tourist time. Pleasant 25–32°C, little rain, low humidity. In northern Thailand (Chiang Mai, Chiang Rai), it can drop to 10–15°C at night — a jacket should be in your luggage.

Regional Differences

The crucial difference: Gulf of Thailand (Koh Samui, Koh Phangan, Koh Tao) and Andaman Sea (Phuket, Krabi, Koh Lanta) have opposing monsoon seasons:

• Andaman Sea: Rainy season May–October, best time November–April
• Gulf of Thailand: Main rainy season October–December, best time February–September

This means: Somewhere in Thailand, the weather is always good. When it rains on the Andaman Sea, the Gulf is sunny — and vice versa.

Thailand's natural beauty is under significant pressure. As a responsible traveler, you should be aware of the main issues — and know how you can be part of the solution.

The Biggest Challenges

• Plastic Pollution: Thailand is one of the five countries that contribute the most plastic to the ocean worldwide. Single-use plastic bags and straws are ubiquitous. Since 2020, major supermarkets have abolished plastic bags, but implementation is inconsistent.
• Coral Bleaching: Rising water temperatures and mass tourism have damaged large parts of the reefs. The government has responded with temporary closures (Maya Bay, Koh Tachai).
• Deforestation: Thailand's forest cover has fallen from 70% (1950) to under 32%. Illegal logging and agricultural expansion (especially for palm oil plantations and rubber) are the main drivers.
• Air Pollution: In northern Thailand (Chiang Mai, Chiang Rai), the air is extremely polluted from February to April due to field burning and forest fires — the PM2.5 value regularly exceeds WHO limits by 10 times. Visiting northern Thailand during this time is a health risk.
• Overtourism: Koh Phi Phi, Phuket, Chiang Mai, and parts of Bangkok suffer from the sheer mass of tourists. The infrastructure (sewage, waste disposal) is overwhelmed in many places.

What You Can Do

• Bring a reusable water bottle (many hotels and 7-Elevens have refill stations)
• Actively refuse plastic bags and straws: "Mai ao tung" (no bag), "Mai ao lot" (no straw)
• Choose local accommodations instead of international chains — the money stays in the community
• Use reef-safe sunscreen when snorkeling and diving
• Support Community-Based Tourism (e.g., local homestays in Isan or with hill tribes)
