Cuba is a huge destination for Canadians: 900,000 visited
Cuba in 2010. For those of you south of the border in the
US, it is less common. Approximately 400,000 US citizens
visit Cuba per year, mostly those with family on the island.
It presently violates US law for most Americans to spend
money in Cuba unless you obtain a permit, and is punishable
under the Trading with the Enemy Act, a WWI-era law.
But the fact is that many Americans, including many divers,
do visit Cuba by traveling through Canada, Mexico (often
Cancún) or Nassau. Cuban officials do not stamp US passports.
The Obama administration has relaxed some restrictions,
so the situation is headed in a positive direction. The
Moon guidebook reports that only two persons have ever
been prosecuted; both ended up fined. Nonetheless, it is illegal
for US travelers to spend any money in Cuba, and those
who do choose to circumvent US law do so at their own
risk, which may count as soft adventure.
