I have researched and just cant decide what areas to cover, i like scuba diving, white beaches and exploring remote islands like you get in Asia.
Central America doesn't have anything like the profusion of white sand beaches and great diving/snorkeling places you can find in SE Asia. For that you're limited to a few areas, like the Belize cayes, the Honduras Bay islands, and also the Corn islands off the coast of Nicaragua. Also a few places in Panama like Bocas del Toro.
Central America does work better as a place for hiking trips and volcano summits, and the surfing beaches on the Pacific coast are much more numerous than good snorkeling/diving places on the Carib coast.
And 2.5 weeks is not much time. You could spend the whole time in Guatemala, doing highland treks there with quetzaltrekkers. Or you could go to Nicaragua, fly to Corn islands, and then split the rest of your time between Leon and Granada/Masaya, and also Ometepe island. There are tons of volcanoes to be explored between all those Nicaragua areas.
