This is the long day, and it is worth it. Materuni in the morning while it is cool and the light on the falls is good, Chemka in the afternoon when the heat has built and the water is the only place you want to be. The two sit on opposite sides of Moshi, which is why most operators sell them separately — the driving is the cost. Done as one trip it makes a complete day, and the contrast between the two is the point: cold mountain forest before lunch, warm lowland spring after.
Morning: Early start, around 7am, to get up to Materuni before the day’s crowd. The 45-minute walk down to the falls, the swim if you want it, then back up to the village for the coffee process — picking, pulping, roasting over the fire, grinding to the song, drinking what you made. Chagga lunch in the village.
Midday: The transfer to Chemka takes between an hour and 90 minutes, dropping from 1,300 metres down into hot acacia country. This is the part of the day where most people sleep in the vehicle, and that is fine.
Afternoon: Chemka is spring-fed, constantly around 27°C, and clear to the bottom. Swim, use the rope swing, or lie in the shallows near the source where the sand bubbles. Two hours here is enough to feel like the morning happened to somebody else.
We are usually back in Moshi around 6pm.
Be realistic about this day. It is roughly eleven hours door to door, involves a real hike and a lot of driving, and if you are jet-lagged or acclimatising for Kilimanjaro it may be more than you want. Split across two days it is gentler and costs a little more. We would rather tell you that now than have you exhausted at the halfway point.
What to bring: swimwear and a towel you can use twice, walking shoes for the morning, sandals for the afternoon, sunscreen, and a change of clothes. Both swims are worth doing properly.
