Lake Chala is one of Tanzania’s most visually extraordinary natural features and one of its best kept secrets. A volcanic crater lake straddling the Tanzania-Kenya border approximately 55 kilometres east of Moshi, Chala sits inside a steep 70-metre caldera whose walls drop dramatically to a surface of water so vividly coloured shifting between deep turquoise, emerald green, and clear azure depending on the light that photographs of it look almost too beautiful to be real.
The lake is fed entirely by underground springs from Mount Kilimanjaro’s vast water table and has no surface outlet. Its geological age is estimated at over 250,000 years. A unique species of tilapia — the Lake Chala tilapia — evolved in complete isolation in these waters and is found nowhere else on Earth. This guide covers everything you need to know to make the most of a day trip to Lake Chala from Moshi.

Getting to Lake Chala
Lake Chala is located approximately 55 kilometres east of Moshi, a drive of approximately 1 hour on the road toward Taveta (the Kenyan border town). The route passes through dry Maasai steppe, small farming communities, and a landscape that gradually transitions from the fertile Kilimanjaro foothills to the drier eastern plains. On clear mornings, Kilimanjaro is visible behind you as you drive east — one of the finest views of the mountain available from road level.
Serac Adventure picks up all clients from their Moshi hotel for the Lake Chala day trip. A 7:00am departure is recommended to arrive before the heat of midday and to take advantage of the morning light on the lake surface.
The crater descent
Lake Chala is not visible from the road — the crater rim must be reached on foot before the lake reveals itself below. A short walk from the Lake Chala Safari Camp through scrubby savannah brings you to the crater rim, where the first view of the lake stops almost every visitor in their tracks.
The descent into the crater follows a steep but well-maintained path — approximately 70 metres down to the lake shore. The path winds through dense vegetation including fig trees, cacti, and aloe, with the lake expanding below you as you descend. The descent takes approximately 20–30 minutes and requires reasonable balance and sure footing proper shoes are essential. The ascent on return takes slightly longer and is more demanding on the legs.
Activities at Lake Chala
Kayaking
Kayaking on Lake Chala is one of the finest water-based experiences available in northern Tanzania. Single and double kayaks are available from the camp at the lake shore. The lake surface is almost always calm protected from wind by the high crater walls making kayaking accessible for beginners and experienced paddlers alike. A full circuit of the lake by kayak takes approximately 1.5–2 hours depending on pace and includes the remarkable experience of paddling from Tanzania into Kenya without leaving the water.
Looking down into the water from the kayak is extraordinary — the clarity is such that you can see clearly to 5–6 metres depth, watching the tilapia moving below and the rocky crater walls descending into the deep blue.
The border rock stand in two countries at once
One of Lake Chala’s most memorable experiences is the walk or kayak to the famous ‘border rock’ — a large rock in the northern section of the lake that sits precisely on the Tanzania-Kenya border. Standing on or beside this rock — or reaching it by kayak — allows you to be literally in two countries simultaneously. Your guide explains the history of the border demarcation and the lake’s position spanning both nations.
Swimming
Swimming in Lake Chala is permitted and popular. The water is cool (significantly colder than Chemka Hot Springs approximately 20–22°C), very clear, and deep. The entry points from the shore involve scrambling over rocks — water shoes are recommended. Not suitable for very young or non-confident swimmers due to depth and lack of gradual entry.
Crater rim hiking
A trail follows the crater rim for a partial or complete circuit (approximately 4km for the full rim). The rim trail offers extraordinary views down into the lake and out across the Maasai steppe toward Kilimanjaro. Early morning rim walks have the best light and frequently produce sightings of birds of prey, baboons, and occasionally elephant near the water sources below.
Birdwatching
Lake Chala and its surroundings host over 200 recorded bird species, including African fish eagle, pied kingfisher, malachite kingfisher, augur buzzard, and a variety of waders and waterbirds along the lake shore. The forested sections of the crater walls host colobus monkey, blue monkey, and vervet monkey — providing excellent wildlife watching without requiring any specialist effort.
What to bring
- Good walking shoes or hiking boots — the crater descent is steep and rocky
- Swimwear if you plan to swim — the water is cool but refreshing
- Sunscreen — the lake surface reflects UV intensely, and the crater offers limited shade midday
- Binoculars for birdwatching on the rim and from the kayak
- Camera with a wide-angle lens — the crater panoramas reward wide framing
- Light layers for the drive back in the afternoon if it is breezy
Frequently asked questions: Lake Chala
Is Lake Chala safe to swim in?
Swimming at Lake Chala is generally considered safe for confident adult swimmers. The water is clear and clean. There is no surface inflow of contaminated water. The depth (90+ metres) and rocky entry points mean this is not recommended for young children or non-swimmers. Always swim with a companion.
Are there crocodiles in Lake Chala?
This is a frequently asked question. Lake Chala Safari Camp and local guides confirm that the lake does not have a dangerous crocodile population accessible to swimmers in normal areas. The isolated location and lack of surface river connections make large crocodile populations unlikely. That said, always follow your guide’s advice on safe swimming areas.
Can I kayak to Kenya?
Yes — the lake straddles the Tanzania-Kenya border, and kayaking from the Tanzania shore to the Kenyan side of the lake is entirely possible. You are not crossing any controlled border checkpoint — the border runs through the water — so this is a memorable experience rather than a bureaucratic one. Ask your guide to point out the border line on the water.
