Overview

อุทยานแห่งชาติเอราวัณ • Erawan National Park

Established in June 1975 as Thailand’s 12th national park, Erawan protects 550 square kilometers of limestone mountains, deciduous forest, and the famous seven-tiered travertine waterfall that gives the park its name. Located in the Tenasserim Hills of Kanchanaburi Province, the park is a 3-hour drive from Bangkok—making it one of Thailand’s most accessible natural wonders.

The waterfall is named after Erawan, the three-headed white elephant of Hindu mythology who carries the god Indra. The top tier is said to resemble this sacred creature, and the name symbolizes protection and purity in Thai-Hindu tradition.

For medical tourists, Erawan offers a unique therapeutic experience: naturally occurring Garra rufa (doctor fish) provide a free fish spa in the emerald pools, while the shaded jungle trail offers gentle forest bathing. The lower tiers are accessible for those in early recovery stages, though the upper tiers present genuine challenges with steep stairs and slippery terrain.

Important: Park fees, hours, and trail conditions are subject to change. Upper tiers may close during monsoon season due to flash flood risk. Verify current conditions at the official DNP website or Erawan National Park Facebook page before your visit.

The Seven Tiers

Each of Erawan’s seven waterfalls has a unique character, Thai name, and difficulty level. The tiers are spread across a 2 km trail from the visitor center.

Tier 1: Hlai Khuen Rung (ไหลคืนรุ้ง)

Flowing Colors of the Rainbow

A series of low cascades with distinctive travertine deposits that resemble cave stalagmites. The first tier offers your first encounter with the emerald pools and Garra rufa fish. Life jacket rental station is located here (20 THB for 2 hours, mandatory for swimming).

Tier 2: Wang Macha (วังมัจฉา)

Fish Pond

A single high waterfall plunging into a deep pool—one of the park’s most popular swimming spots. The Thai name means “Fish Pond” (Macha is poetic Thai for fish). Adventurous swimmers can pass behind the waterfall curtain and climb onto a hidden rock ledge.

Tier 3: Pha Namtok (ผาน้ำตก)

Waterfall Cliff

The most impressive single drops of the waterfall system, with a spacious swimming area that can accommodate many visitors. This is the last tier easily accessible for those with limited mobility.

Tier 4: Oke Nang Peesau (โอกนางเปสือ)

Serpent Maiden’s Pond

Famous for curved rocks that form a natural water slide—visitors slide down the smooth limestone into the pool below. This is the last easily accessible tier before the trail becomes more challenging.

Tier 5: Buea Mai Long (เบือไม่ลง)

Cannot Be Reached by Boat

A multi-level cascade with several small drops creating multiple spacious pools. Many consider this tier among the most beautiful, with fewer crowds than lower tiers.

Tier 6: Dong Prucksa (ดงพฤกษา)

Forest of Trees

A wide, multi-tiered cascade set deep in the forest. Reaching this tier requires crossing the river—water levels vary by season, making the crossing more challenging during or after rain.

Tier 7: Phu Pha Erawan (ภูผาเอราวัณ)

The Cliffs of Erawan

The triumphant destination. Water appears to emerge from the mountaintop itself, tumbling over large boulders into the pool below. The shape of the falls is said to resemble the three-headed elephant Erawan. The final 200 steps are steep and strenuous but rewarding.

Last Entry: Rangers begin clearing visitors from Tier 7 at 15:00, working their way down. Plan accordingly.

Trail Guide

Main Trail: Erawan Falls Trail

Trail Conditions by Section

Hiking Strategy

Option 1: Summit First (Recommended for fit visitors) Hike directly to Tier 7 when you arrive at 08:00, then swim and relax on the way back down. This ensures you reach the top before the 15:00 cutoff and enjoy the pools when you’re tired.

Option 2: Progressive Exploration Stop at each tier on the way up, swimming and photographing as you go. Risk: You may not reach Tier 7 before cutoff if you spend too much time at lower tiers.

Option 3: Lower Tiers Only (Recommended for recovery) Focus on Tiers 1-3 or 1-4 for the core Erawan experience with manageable walking and excellent swimming. Most visitors never reach the upper tiers anyway.

Activities & Experiences

Swimming

Swimming in the emerald travertine pools is Erawan’s signature experience.

Swimming Tips:

• Bring water shoes for grip on slippery rocks
• Use a dry bag for phones and valuables
• Apply sunscreen before entering the park, not at the pools
• Respect other swimmers; the pools get crowded on weekends

Natural Fish Spa (Garra rufa)

The lower pools are home to naturally occurring Garra rufa fish—the same “doctor fish” used in commercial fish spas worldwide.

Note: Commercial fish spas in Bangkok charge for this experience. At Erawan, it’s natural and free. However, those with open wounds, compromised skin, or recent incisions should avoid letting fish nibble on affected areas.

Cave Exploration

Phra That Cave (ถ้ำพระธาตุ)

The main accessible cave features impressive stalactites and stalagmites with bat colonies deeper inside. The path passes through bamboo forest.

Other Caves:

• Wang Bahdan Cave: Closed to visitors for several years
• Mi Cave and Rua Cave: Limited visitor access

Wildlife Watching

Wildlife viewing is limited along the main waterfall trail due to crowds, but early morning and late afternoon offer the best opportunities.

Important Wildlife Rules:

• Never feed macaques — They will approach and may become aggressive
• Secure all food and belongings
• Maintain distance; do not attempt to touch or chase animals
• The park’s 550 sq km supports elephants, leopards, and other large mammals, but these are rarely seen near the popular waterfall area

Photography

Photography Tips:

• Waterproof bag or case is essential
• Early morning (08:00-09:00) offers soft light through the canopy
• Weekdays have significantly fewer visitors in frame

Procedure-Specific Guidance

Special Considerations

Swimming After Surgery:

Heat and Humidity:

• Bring plenty of water; stay hydrated
• Rest at each tier as needed

Slippery Conditions:

• Wooden planks and rocks are slippery, especially after rain
• Wear water shoes or sturdy sandals with grip
• Patients with balance issues should exercise extreme caution or consider lower tiers only

Why Erawan Suits Medical Tourists

• Forest bathing: Shaded jungle trail supports stress reduction and mental wellness
• Low-impact swimming: Buoyancy reduces strain on recovering bodies
• Tiered difficulty: Choose your own adventure based on recovery stage
• Day trip possible: 3 hours from Bangkok hospitals
• Cooler than Bangkok: Forest shade provides relief from urban heat
