I've done a ruins trip that was great...I know of people who have done the cave tubing and they said that was really good too.For the folks that have been to Belize - what side trips do you recommend for someone that's never been there?
On The Tides website, they have this one Cave tubing w/ Xunantunich...Xunatunich is one of the sites I've been to and it was really interesting;
I'd probably do this one Altun Ha Ruins or this one Lamanai Ruins
