las lenas has an allright park, nothing compare to us, but 2 medium jumps and a nice line of about8-10 rails...
but if you go to las lenas go to the backcountry!!!!!
if you want the best parks in south america you should check chapleco's park in San martin (it had 3 NICE jump in line pretty big) and couple of rails and a high speed cuad next to it. or el colorado (that;s in chile) haven't been there but they say it;s reaaly good
and also for BC go to catedral in bariloche, best town, best parties.. best resort all around
