During my drive along the north coast of Timor, there were no shortages of empty beaches and coves. Among them, I found this particular beach to be the best. The beach was about 2km long and I did not see another person, nor even see a car pass the road for over two hours.
The sand is soft and clean. The water is warm and visibility is great. There are absolutely no facilities here, so bring everything you need.
Do not worry about crocodiles here. The water is clear, there are no rivers to silt things up, nor are there mangroves which they like to loiter in.
At the far east edge of town, there is the remains of the old Portuguese House. Back when Timor was a Portuguese colony, the Portuguese could be found at various places on the island to help facilitate trade, administration, etc.
Just a few minutes walk past the Com pier, past what I have named "Goat Beach", you can find the foundations and walls of the old Portuguese colonial house. I've asked the locals if they know how old it is, or what its original function was, but none could give a definitive answer. All I know is that the house has been there for well over a hundred years.
The roof is gone and the windows are open. Bushes grow out of the floors and stairway, but with a little imagination, you can see what it used to be like.
The people in Com live modest lives and they survive mostly with the income earned from the few "tourists" that come to town. I use that word loosely because most are expats from Dili who come to relax for the weekend.
There are half a dozen ladies on the street selling TAIS. If you wish, haggle for a good price and share so of those hard earned dollars with the locals.
Many of the locals are also trying to subsidize their incomes by operating Guest Houses. They are cheaper than the Beach Resort (about $5 a night).
Regardless of what the locals are trying to do, they are very welcoming and greet you with smiles and waves. A few have studied English and are eager to practice it. Even if you don't intend to buy anything, take a few minutes to say hello, get to know the locals and share some cultural anecdotes.
