I would have to say I like this beach waaay more than Chenang because it is quiet and less crowded. Im not a huge fan of crowded beach, i think it defeats the purpose of the word relaxing.
Tengah is where you can just spread your mat anywhere without being disturbed by people walking or vehicles running at the beach. This is the place where you can lie down and start reading a good book or put your earphones on and listen to some reggae music while getting a tan :)
If I am to go back to Langkawi, I will spend more time on this beach, just enjoy looking at the horizon during sunset/sunrise.
Dont worry though, this beach may be less crowded but it is accessible to many restos, bars and shopping area. Chenang beach is actually just a walking distance from this place.
