Formerly, if you wanted to go down towards Temple Point, you could only get a matatu as far as the Turtle Bay Hotel, and then you were stuck and had to walk the remaining 2 miles or so. These days, you can hop on a so-called "boda-boda" for the rest of the way. Boda-bodas are bicyles with a passenger seat stuck on the rear, and for around 20-30 KSH those guys will give you a lift for the rest of the way.
It's not the most comfortable mode of transport, but still preferable to walking down the road in the heat. And there's usually lots of boda-bodas hanging around Turtle Bay, so you shouldn't have any trouble catching one there.
The best way to get around Watamu is by bicycle. Once you have passed the busy part of the road down to the Turtle Bay Beach Hotel it is a very nice cycle down to Mida Creek and the Marine National Park at Temple Point. Also to Gedi it is only a 20 – 30 minute trip on the bicycle.
If there is a problem with the bicycle just go to one of the bicycle repair shops. Well, shop is a bit of an overstatement, as they are basically one or two guys sitting under a tree with a tool kit waiting for customers, who will fix a flat tyre for less than 1 Euro.
Bicycle rental is readily available in Watamu.
If you don’t fancy going on a bicycle matatus are the other obvious mode of transport, and there are more than enough of them in Watamu. They go to Gedi (Ksh 30) and Malindi (Ksh 50) every couple of minutes, and you can board them either at Mama Lucy’s supermarket, Watamu junction or at Turtle Bay Beach Hotel.
Beware of them, though, if you are a pedestrian. The vehicles with little confidence-inspiring names like “Bad bugs”, “Instant brakes”, “Think twice” or “Ooops” race along the roads at breakneck speed, hooting at everything that they perceive to be in their way when they are still about half a mile away, and making pedestrians, cyclists, goats and hens flee in unison to the side of the road.
Every time I visit Watamu yet another mode of transport seems to be available, and this time it was the tuk tuks.
They are small three-wheeled vehicles, which are cheaper than taxis but more comfortable than boda-bodas, especially if you travel with luggage. We actually managed to squeeze into the backseat with 4 people, and there was also some storage room behind us for our luggage.
Your best bet is to find a reliable tuk tuk driver and then get his mobile phone number. Our guy always arrived within 15 minutes at the latest to pick us up at the door, and was very friendly and helpful in general.
