Belize in $530s-$590s RT

Fun fact: The fear of the deep ocean is called thalassophobia.

Funner fact: Just off the coast of Belize, there's a perfectly circular sinkhole in the seafloor that goes down hundreds of feet into the abyss!

Maybe-less-fun fact: If you have thalassophobia, you might want to skip this video.

The Great Blue Hole's unique formation makes it one of the best scuba spots in the world, but people who aren't half-mermaid might prefer to take a boat or helicopter tour. That dark blue circle is pretty striking from any angle.

And of course, the rest of that turquoise Caribbean water is gorgeous anyway :-)

P.S. Dates for this one are a bit tricky to scare up, so we included several below to get you started. Most dates are at $575 RT but we spotted a handful of dates $20-$40 RT cheaper, so don't be afraid to hunt around

P.P.S. Some of these American websites don't like to show currency in CAD. If you book with Alaska, you can use their currency converter to see your final price in CAD, and then pay in USD.
