Chemka Hot Spring sits inside a collar of palm trees about 45 minutes west of Moshi, near the village of Sanya Juu. The water runs at around 35°C — warm enough to feel immediately different from any river you have swum in, clear enough to see the sandy bottom through six metres of water. You can swim, float, or just sit on the edge with your feet in.
Most visitors come for a few hours and wish they had stayed longer. We arrive mid-morning, eat lunch beside the spring, and stay until the afternoon light changes. There is nowhere to rush.
Getting there
The drive passes through Chagga farmland below the Kilimanjaro foothills — banana groves, coffee plantations, the smell of the mountain coming down in the morning air. We stop briefly at a lookout point where on clear days you can see Kilimanjaro from the plains before the forest closes in. The road to the spring itself is unpaved; we use a 4WD.
The water
The spring is geothermal — fed by water heated underground and rising through fissures in the volcanic rock beneath this part of Tanzania. It flows continuously, which means the pool is always fresh. The temperature is consistent year-round. It is safe to swim; many local families bring their children here.
The setting is remarkable: the spring sits in a hollow almost completely enclosed by mature palm trees, so you swim in filtered green light even at midday. It is the kind of place that is genuinely hard to photograph — the atmosphere does not translate.
What's included
Transport from Moshi, guide, entry fee, and a packed lunch we prepare from local ingredients. Bring a towel, swimwear, and sunscreen. Water shoes are useful but not required — the bottom is sandy.
