Into Hiyare’s Green Room: A Day Hike from Galle to a Hidden Waterfall
A guided ramble from Unawatuna’s coast to a quiet rainforest plunge—mud, spice, and a waterfall all to yourself.
Morning comes slow in Sri Lanka’s southwest, and the rainforest likes it that way. The canopy lifts its eyelids one leaf at a time, cicadas warm their engines, and mist pads silently across the Hiyare hills as if it were taking attendance. Eighteen kilometers inland from Unawatuna’s surf, a narrow footpath slips between cinnamon shrubs and rubber trees, the soil red and tacky underfoot. It’s here that the Hiking Day Tour begins—part village walk, part jungle ramble, and a steady conversation with water that ends in a plunge beneath a local-loved waterfall few outsiders ever see.
Trail Wisdom
Start Early, Beat the Heat
Aim to hit the trail by 7–8 a.m. to make the most of cooler temps and calmer forest activity.
Leech Defense
Wear leech socks or snug, high socks and carry a small salt packet; leeches are common in wet sections year-round.
Grip Matters
Muddy roots and wet rock are standard—trail shoes with sticky soles make the day safer and more enjoyable.
Swim Smart
At the waterfall, stay within the calm eddies and avoid the direct base of the fall where currents can be deceptively strong.

Conservation Note
Local groups support habitat corridors and research around Hiyare. Stay on established paths, pack out all waste, and avoid soaps or detergents in stream and waterfall areas.
Hiyare Reservoir was constructed in the early 20th century to supply water to Galle, and the surrounding lowland rainforest reflects a mosaic of village lands, spice plots, and conserved habitat.

Photographer's Notes
What to Bring
Lightweight Trail Shoes with Aggressive TreadEssential
Wet roots and slick laterite demand sure footing to keep the hike efficient and safe.
Leech Socks or Tall, Snug Hiking SocksEssential
In a wet rainforest, leeches are part of the ecosystem—proper socks keep them off your skin.
Breathable Rain JacketEssential
Pop-up showers are common; a light shell keeps you dry without overheating.
Dry Bag (5–10L)
Protect phones, cameras, and a spare layer from rain and waterfall spray.
Common Questions
How long is the hike and how difficult is it?
Plan for 6–7 hours round-trip with moderate difficulty—expect humid conditions, muddy sections, and some short, steep pitches.
Can I swim at the waterfall?
Yes. There’s a natural pool suitable for a refreshing dip, but stay within calm eddies and avoid the direct plunge where currents are stronger.
What should I wear on my feet?
Closed-toe trail shoes with good grip are best. Avoid flip-flops or slick-soled trainers due to wet roots and rock.
Are leeches an issue?
Leeches are common after rain. Wear leech socks or tall, snug socks and bring a small packet of salt to remove any that latch.
Do I need a permit?
No formal permit is typically required for this guided day hike, but follow your guide’s instructions and respect local access across village lands.
Is the hike suitable for kids or older travelers?
Active children and fit older travelers who are steady on uneven terrain usually manage well. The guide can set a relaxed pace with plenty of breaks.
What to Pack
Leech socks or tall snug socks (for rainforest critters); 2–3 liters of water with electrolytes (humidity dehydrates fast); Lightweight rain jacket (showers come quickly); Compact towel and swimwear (for the waterfall pool).
Did You Know
Sri Lanka’s southwest wet zone hosts one of the highest rates of amphibian endemism in Asia, with over 80% of amphibian species found nowhere else.
Quick Travel Tips
Use the Southern Expressway from Colombo to Galle to cut travel time; Carry small bills for tea stalls and tips; Download offline maps—cell service can be patchy in the forest; Keep electronics in a dry bag—humidity and sudden rain are constant companions.
Local Flavor
Back in Galle, refuel with a crab curry and pol sambol at a family-run kade, then find a lime soda on Pedlar Street inside Galle Fort. If you’ve got room, hunt down fresh hoppers with a runny egg for a simple, perfect finish to a rainforest day.
