Hi,
I am a Canadian and have lived in Honduras 16 years. I have traveled extensively in the country and know it pretty well. I have homes in Roatan and Valle de Angeles. These are the two safest and most beautiful parts of the country with many great things about each of them. That being said, once you are out of the 3 major cities most of the towns are pretty safe and the country is beautiful. Valle de Angeles would be my first recommendation for you if you want to be reasonably close to the family property. It is a little less than 2 hours away. Every weekend is a fiesta there with hundreds of people from Tegucigalpa coming into town. There is lots to see and to do so people love it. During the week it is very quiet. Most of the wealthy and powerful people in the country have homes here so that is one reason it is so safe. The next best choice would be Cedros. It is a little less than an hour from El Terrero and is very pretty as well. I have always felt very safe there. It would be a lot less expensive than Valle as there isn't much there in the way of entertainment or excitement but it is pretty. Hopefully this will give you some direction. Good luck!
Best of Life!
