So much that could be said… 

Might be worth it to pay up for exceptional hotel hot spring amenities up the mountain in La Fortuna.  Can get day passes.   Sky bridges pretty cool.  Visit the namesake waterfall for a swim in pristine water and an amazing view.   Other waterfalls,too.   Whitewater rafting if you’re into it…. If you want to wake up early you can see some wildlife with a guide traveling up toward Nicaragua.   Really beautiful all around town.   

Fried fish casados all day…

Jaco is lively.   When I get near the beach I just start thinking ceviche ceviche ceviche.   

Good luck.  hope y’all have fun.   PV!
