there is a cruise ship port on the pacific coast so they run a lot of day trips from there to Antigua [thus the good road]. Monterrico is just a one street strip of low range hotels but the food where i stayed was surprisingly good.
i did go to the much larger turtle 'sanctuary' here but it felt much more commercial than the smaller one i visited last year but i got to see something just as spectacular here. i was on the beach early in the morning and there was a WHALE just offshore. it was playing for about 30 minutes and it was amazing to watch it in it's natural environment and not in some small concrete tank in an amusement park.
