There are over 50 alpine lakes scattered across the Swat Valley. Most tourists never hear about them. Andrab Lake — locally called Kooh Lake, meaning “colour changing lake” is the one that quietly earns its reputation among the hikers who make it there. Sitting at 10,800–11,000 feet above sea level in the Anakar Valley near Kalam, this glacial lake shifts from deep blue to brilliant green as sunlight moves across its surface. It’s not a trick of the light; it’s the lake doing what no other lake in Swat can do quite the same way.

This guide covers everything you need to plan your Andrab Lake trek — altitude facts, month-by-month conditions, trail details, what to pack, and how to get there from across Pakistan.

What Makes Andrab Lake Different from Other Swat Lakes

Most lakes in Swat get to you by jeep. Andrab Lake asks you to earn it.

The 7–8 hour return trek from Blue Water Point is what keeps the crowds thin and the lake pristine. You won’t find the food stalls and trash piles that crowd spots like Mahodand in peak season. What you will find: a high-altitude lake with water so clear it mirrors the surrounding ridges, alpine meadows (locally called maidan) ideal for camping, and the kind of silence that only comes from being genuinely far from the road.

It also stands apart geologically. Unlike static glacial lakes, Andrab’s surface reads the sunlight — early morning it sits heavy and blue; midday it tips toward jade-green. Photographers should plan to arrive by 9–10 AM for the best colour contrast before overhead light flattens it out.

Key Facts at a Glance

Getting to Andrab Lake: Step by Step

From Islamabad

The most common route is to depart Islamabad overnight and reach Bahrain or Kalam by early morning — a journey of roughly 7–8 hours by road via Mingora. From Islamabad, take the M-1/N-95 toward Swat, passing through Chakdara, Mingora, Bahrain, and then up to Kalam Bazaar (approximately 326 km total).

From Peshawar

Peshawar to Kalam via the Swat Motorway takes around 4–5 hours in good traffic conditions.

From Kalam Bazaar to Blue Water Point

Once you reach Kalam Bazaar, you need to get to Blue Water Point in Ankar Village — this is where your trek begins. Hire a local jeep from Kalam Bazaar; the ride takes 30–45 minutes on a rough mountain track. Always confirm the jeep rate before you start (rates vary by season; expect PKR 1,500–2,500 one way in 2025).

The Trek Itself

From Blue Water, the trail follows a stream upward through the Anakar Valley. The path runs alongside the flowing water most of the way, which makes navigation straightforward and the scenery consistently good. You’ll pass through dense green meadows, patches of wildflowers in summer, and open pastures where local Gujjar herders often camp with their livestock.

Trail notes:

• The first 2–3 hours are relatively gentle along the stream bank
• The final push before the lake gains elevation more sharply
• Total return: 7–8 hours at a moderate hiking pace; faster trekkers can do it in 5–6 hours
• You can also camp overnight at the meadows near the lake and return the next morning — the most rewarding option

Month-by-Month: When to Visit Andrab Lake

Bottom line: June and September give you the lake with fewer people and better weather for photography. July–August is peak season with the widest range of services available in Kalam.

How Difficult Is the Andrab Lake Trek?

Rated easy to moderate, this trek suits most people who are reasonably active — you don’t need prior mountaineering experience. That said, “moderate” at 11,000 feet is different from “moderate” at sea level.

Fitness guide:

• Suitable for: Hikers who walk regularly, families with older children (12+), groups of mixed fitness levels willing to go at their own pace
• Challenging for: People with joint problems, those unaccustomed to altitude, or anyone with cardiorespiratory conditions
• Not recommended for: Children under 10, elderly with mobility issues, anyone with acute altitude sickness history

Some trekkers feel breathlessness or mild headaches as they gain altitude above 9,000 feet — this is normal. Go slow, drink water regularly, and don’t skip snacks. If you feel dizzy or nauseated above the midpoint, descend; don’t push through.

What to Pack for the Andrab Lake Trek

The altitude means temperatures drop significantly from valley floor to lakeshore, even in summer. Pack for both.

Clothing:

• Lightweight moisture-wicking base layer
• Warm mid-layer (fleece or down jacket — mandatory even in July)
• Waterproof windbreaker
• Comfortable trekking pants (not jeans)
• Sturdy hiking shoes or trail boots (broken in, not new)
• Warm socks (at least 2 pairs)
• Sun hat and light gloves

Gear & Supplies:

• At least 2–3 litres of water per person (refill from stream at your own risk — boil or purify)
• High-energy snacks: dry fruit, nuts, biscuits, energy bars
• Sunscreen (SPF 50 — UV is stronger at altitude)
• Sunglasses with UV protection
• First-aid kit: blister plasters, paracetamol, rehydration sachets
• Trekking poles (optional but helpful on the descent)
• Fully charged power bank and camera

For Overnight Camping:

• Lightweight sleeping bag rated to 0°C or below
• Compact tent or ask your guide about renting locally in Kalam
• Extra food for dinner and breakfast
• Headlamp or torch

Camping at Andrab Lake

Staying the night near the lake is the part most day-trekkers regret skipping. Once the afternoon hikers turn back, the valley goes quiet. You’ll have the lake to yourself — the colour shift at golden hour (around 5:30–6:30 PM in summer) is unlike anything on the way up.

The meadows near the lake — open, flat patches of grass — are the standard camping area. There are no formal facilities; bring everything you need. Local guides can advise on the safest camping spots away from stream flood paths.

A good setup: depart Blue Water by 7 AM, reach the lake by 1–2 PM, set up camp, explore the lakeshore in the afternoon, photograph the evening light, sleep under the stars (on clear nights, the Milky Way is visible from here), and descend the next morning.

Photography Tips: Getting the Colour Change on Camera

Andrab Lake is exceptionally photogenic — but only if you time it right.

• Best light: 8–10 AM (golden morning light on the water before the sun gets overhead)
• Colour contrast: The blue-to-green shift is most visible when the sun is at a low angle — early morning and late afternoon
• Reflections: Shoot from the northern bank to capture the surrounding ridges in the water on calm days
• Wide angle lens: The open meadow behind you and the lake in front make for strong landscape compositions
• Avoid midday (11 AM–2 PM): Overhead light washes out the colour variation; the water looks flat
• Camera protection: Bring a waterproof bag or case — afternoon showers are common in July and August

Other Treks You Can Do From Blue Water Point

Blue Water is not just the gateway to Andrab Lake. From the same starting point, experienced trekkers can branch out toward:

• Janshai Meadows — a high-altitude meadow popular for its wildflower fields
• Mastuj Lake (Mastuj Danda) — a more remote option requiring a guide and overnight camping
• Ankar Valley exploration — the valley itself offers multiple side trails worth half-day exploration

If you have 3–4 days in Kalam, consider combining Andrab Lake with one of these for a multi-day backcountry experience.

Where to Stay: Accommodation in Kalam

Since the trek begins from Blue Water Point outside Kalam Bazaar, most travellers base themselves in Kalam town and take a jeep to the trailhead each morning.

Budget options (PKR 2,000–4,000/night): Basic guesthouses in Kalam Bazaar with clean rooms and shared or attached bathrooms. Ideal if you’re a solo traveller or small group keeping costs low.

Mid-range (PKR 4,000–8,000/night): Several hotels near the river in Kalam offer riverside rooms with mountain views, hot water, and meals included. These fill up fast in July and August — book at least a week ahead in peak season.

For families: Look for family rooms or adjoined rooms in mid-range properties; Kalam has good options for groups of 4–8 people.

No accommodation exists at the lake itself — camping is the only option for those staying overnight near Andrab.
