Chemka Hot Springs

Chemka, properly called Kikuletwa, is a spring-fed pool in a grove of fig trees on the plain between Moshi and Arusha. There is nothing else like it within reach of either town.

The water comes up through the ground from Kilimanjaro, filtered through decades of volcanic rock. It arrives extraordinarily clear, and it stays a comfortable temperature all year.

"Hot springs" oversells it. The water is warm, not hot, at about body temperature. That is exactly why you can stay in it for hours.

The pool sits in an oasis of fig trees. Their roots grow down into and around the water, making underwater structures you can swim through and platforms you can jump from. People remember the clarity. You can see the bottom several metres down, and small fish work around your feet.

All around it is dry, flat, dusty acacia country, which makes arriving so startling. There is no gradual change. You come down a rough track and the green simply appears.

It gets busy at weekends and in the middle of the day, so start early.

Chemka is spring-fed, so the water temperature and clarity are essentially constant year-round. Only the road and the crowd change.

The access track across the plain is dusty in the dry season and can be genuinely difficult after heavy rain. In April and May it's worth checking conditions before committing to the drive.

Timing within the day matters more than the season. The site is busiest from late morning through the afternoon, and at weekends it's busy with local visitors as well as tourists. Arriving early gives you the pool close to empty and the light coming through the figs, which is the version worth photographing.

The plain is hot from mid-morning onward and there's limited shade on the walk in from the parking area, so an early start is more comfortable as well as quieter.

Because it's warm, not hot, the water is pleasant in every month. This isn't a place with a season so much as a place with a time of day.

Chemka is close to several other things, which is why it's rarely done alone.

Njoro Forest is the standard pairing. It is a gentle shaded walk to a waterfall with a warm swimmable pool, from the same spring system. The two together make a genuinely good full day of forest and water without a hard climb in it.

Look out for Rundugai and the surrounding irrigated plain on the drive. Some trips include a short village walk.

Lake Chala is further east and makes a different kind of day, but the two are sometimes combined by operators willing to drive.

Moshi is the base for all of this and is around ninety minutes away.

Chemka is also the standard rest day after coming off Kilimanjaro, and the logic is sound: your legs won't take another walk, sitting still in a hotel is a waste of a day, and warm water is exactly what a body that has just descended several thousand metres wants.

A spring-fed pool in a fig grove roughly ninety minutes west of Moshi. Warm, not hot, extraordinarily clear, and with very little walking involved. It is the gentlest of the five day trips and the standard rest day after coming off Kilimanjaro.

Bring swimwear under your clothes, a towel, a dry bag, sun protection and cash for the entrance fee. Do not bring valuables. There's no secure storage and that's the most common problem visitors report.

Go early. The site is busiest from late morning onward and at weekends, and the pool close to empty with light coming through the figs is a completely different place from the pool at noon in August.

For a rest day, yes, clearly. It is ninety minutes each way for several hours in warm, extraordinarily clear water with almost no walking, which is exactly what a body that has just come off Kilimanjaro wants.

For a first-time visitor with limited days and a choice between this and Materuni, Materuni is the more memorable day. A waterfall, a forest walk and a coffee demonstration, against a swim.

The strongest version is both, on separate days from the same base in Moshi, or Chemka paired with Njoro Forest for a single day of forest and water.

There is no secure storage at the site and this is the most common problem visitors report. Take only what you can keep with you or leave in a locked vehicle with your driver, and leave anything you would mind losing at the hotel.
