We're spending a few day at Lago de Izabal, a huge lake at the top of the Rio Dulce.  It's sparsely populated and absolutely gorgeous.  Yesterday we hiked to the thermal pools nearby- one cool pool has a hot waterfall cascading into it, onto your head if strategically placed.  Met some sailors who came down from Texas through the reefs in Mexico and Belize.  That was lots of fun, as we're usually by ourselves.  They left this morning to return to Rio Dulce, but we thought we'd spend a few more days here.  There's a small town nearby, and lots of small rivers to check out.
