We crossed the border into Belize for 2 nights near San Ignacio and 2 nights on Caye Caulker.
In San Ignacio most people went caving or cave tubing. Western Belize is known for its caves. I and some others when to the small nearby ruins at Xunantunich. There’s a hand-cranked ferry that leads to the site.
It’s a small out of the way site, but it does get crowded midday since it’s the closest ruin site to the cruise ship docks in Belize City. We were leaving about the time busses started showing up.
Most of the temples can be ascended, including the highest castillo.
There are some good inscriptions on either side of the castillo. These are actually reproductions; the originals were reburied to protect them.
We traveled by water taxi to Caye Caulker. No ruins there; just beaches and boats.
