Erawan Falls, Kanchanaburi: The 7-Tier Waterfall Hike Explained

Erawan Falls sits inside Erawan National Park, about 65 kilometres north of Kanchanaburi town. The waterfall consists of seven distinct tiers connected by a single trail, with each level offering a different sized pool for swimming. The water gets its signature turquoise-green colour from calcium carbonate deposits that accumulate on the limestone substrate - the same geological process that creates Thailand’s famous cave formations.

Most visitors stop at the lower tiers and turn around, which means the upper reaches are significantly quieter even on busy weekends. The full trail to Tier 7 takes about 1.5 to 2 hours one-way depending on fitness; hiking boots or grip sandals are strongly recommended above Tier 4 where the path gets steep and slippery.

Entry and Opening Hours

• Opening hours: 08:00–16:00 daily (gates close; last entry 15:30)
• National park fee: THB 300 per adult foreigner, THB 100 per Thai adult (as of 2026)
• Parking fee: THB 20–30 per car or motorbike

The park can close temporarily after heavy rain when water levels rise to unsafe levels - this is most likely May through October. Check with your accommodation or the national park hotline before visiting during rainy season.

The Seven Tiers

Tier 1 (Nang Rong) - 10 minutes from the entrance. A wide, shallow cascade over flat rocks into a large swimming area. This is the widest and most photographed point; it gets congested by 10:00.

Tier 2 - 5 minutes from Tier 1. A deeper pool good for swimming; fish here are notably bold and will nibble your legs and feet if you stand still (a free “fish spa” effect that surprises first-timers).

Tier 3 - the start of a steeper section. A good-sized pool beneath a two-stage cascade. Many visitors turn around here.

Tier 4 - one of the more impressive drops, a single curtain of water falling into a circular pool. The trail above here requires some light scrambling over wet rocks.

Tier 5 - a smaller pool, but by this point you’ll likely have it to yourself on most days. Good spot to stop for lunch if you’ve brought food.

Tier 6 - the narrowest pool, enclosed by tall rock walls on two sides. Photogenic but limited swimming space.

Tier 7 (Phrabat) - the uppermost accessible tier, approximately 1.5 kilometres from the entrance. The waterfall here drops about 7 metres into a pool that’s often deserted. The full view of the surrounding forest canopy from the top is the reward for the climb.

A flash flood warning system is installed at several points on the trail; if you hear a siren, move uphill immediately and wait for staff guidance.

Getting There from Bangkok

By minivan (recommended for solo travellers): Several tour operators at Mo Chit Bus Terminal (Bangkok) and from Khao San Road run shared minivan services to Erawan National Park, with departure times typically 07:00–08:00. Round trip including a set time at the falls: approximately THB 700–900 per person. The journey takes around 3 hours each way.

By public bus + songthaew: Take a bus from Bangkok’s Mo Chit terminal to Kanchanaburi town (Bus 81, approximately THB 130, 2.5–3 hours). From Kanchanaburi Bus Terminal, catch a public songthaew (shared truck) to Erawan village (approximately THB 50, 1 hour). Return songthaews to Kanchanaburi typically stop running by 16:00, so plan accordingly.

By rental car or motorbike: From Kanchanaburi town, Erawan is 65 kilometres north on Route 3199. Car rental in Kanchanaburi starts at approximately THB 1,200 per day; motorbike rental from THB 300–400 per day. The road is straightforward and well-signposted.

From Bangkok by guided day tour: Organised day trips from Bangkok combine Erawan Falls with the Death Railway and River Kwai Bridge at Kanchanaburi. These run approximately THB 1,500–2,500 per person via GetYourGuide or local operators, including pickup, transport, and a guide. A useful option if you want to cover both in one day.

What to Bring

• Swimwear - you’ll want to swim at minimum at Tier 1–3; a dry bag for your phone is useful
• Water shoes or grip sandals - mandatory above Tier 3; the rocks are wet and algae-covered
• Cash - there’s a small refreshment stall near Tier 1, but the park is largely cashless in terms of card machines for food vendors
• Food - there’s a basic canteen near the entrance; for a full day including Tiers 4–7, bring snacks or a packed lunch
• Insect repellent - the forest trail above Tier 3 has mosquitoes; apply before entering
• Refillable water bottle - the stream water is not safe to drink, but hydration is important on the upper tiers

Swimming Rules

• Sunscreen must be removed before entering pools - park rangers enforce this at Tiers 1–3 with a quick check; biodegradable sunscreen is sometimes accepted, but chemical sunscreens are not
• Feeding the fish is prohibited (they’re wild; the nibbling happens naturally)
• No alcohol in the swimming areas

Best Time to Visit

November to February is the coolest, driest period. Water levels are stable, trails are less slippery, and the forest is at its most pleasant for hiking. The falls are busiest on weekends and public holidays in this window.

March to May (hot season): water levels drop and some upper pools may be shallower, but it’s the least crowded period for weekday visits.

June to October (rainy season): water volume is spectacular and the green colour of the pools is at its most vivid. However, flash flood risk increases significantly above Tier 3 after heavy rain. The park sometimes closes sections of trail for safety. Worth visiting, but check conditions first.

Combining with Kanchanaburi Town

Kanchanaburi town is worth at least a half-day: the Death Railway Bridge (the “Bridge on the River Kwai”), the Thailand-Burma Railway Centre museum (excellent; entry approximately THB 160), and the JEATH War Museum provide sobering historical context. If you’re driving, the train journey from Nam Tok Station across the Tham Krasae viaduct - a wooden trestle bridge cantilevered over the River Kwai Noi gorge - is one of Thailand’s most scenic rail rides (train from Kanchanaburi station, approximately THB 20, check current schedule at the station).

Most people combine Erawan Falls with Kanchanaburi in a single full day from Bangkok: early departure (06:30), falls in the morning, historical sites in the afternoon, back to Bangkok by 20:00. It’s a long day but very doable.
