This little Provincial Park is open only in the summer and then only from 9 A.M. until 9 P.M, However you can certainly hike down in here whenever you like offseason. BTW The Park manager knows about ( and approved ) the caches. He'll be the one ' over there' chortling at you if you take long making a find. Great spot for a swim and a hike.
