Tenga Beach is divided on a few places, by a rock and then by the road entering but it is quite long and wide. However it offers no shadow what so ever unless you are staying in the resorts.
On Tengah you can do the parashooting and bananaboats and also some Jetskis.
It is definately not my favourite beach on Langkawi but it sure is less crowded than Pantai Cenang.
If you get hungry while on the beach the resorts offer food but if you are on a budget you better get off the beach and to the street instead. Here is a good variety of different food at good prices.
On the beach, by the big rock, is a newly openend bar called the Jam Rock. It is the same owner as the old Babylon on Pantai Cenang and it has the same atmosphear. Opens from 3pm. When I am writing this there is no food served at the JamRock but it will hopefully come in end of fabruary or so.. (Langkawi-time)
