First time I was there was in 2003 with friends. We climbed then not only Placlivy, Ostry Rohac and Volovec, but also Hruby vrch, Jakubina and Otrhance. We achieved 2200 meters of altitude gain at a single day. It was my record at that time.
I was at Ostry Rohac also in 2008 with brother and father in september and it was brilliant, since autumn Tatras are wonderful.
My route that day, 2nd half of August 2004: village of Ziar-mouth of Rackova (Uzka) dolina-Jamnicka dolina–Ostry Rohac-Placlive-Smutne sedlo-Ziar.
I swayed in the Notch, shouldn't have been "jogging". For more, see the last lines of paragraphs 3 and 4.
