I done two routes from the wall Bucura II: Creasta Vulturilor 3A and 25 Octombrie 3B. I liked so much. Weather not so god, cloudy and rainy.
Towards the end of our Gemenele loop (via a marked trail, past both Negru and Gemenele tarns) we ran into a bunch of scientists and rangers. After I'd explained there was no clear "Keep off" sign at the pass between the Sesele Mare and Mici, they let us off but told us to turn left and climb up the slope of the ridge between Retezat pass and Bucura Peak. On the way, we ran into a herd of chamois, and on top of that - and literally at the top of Bucura - we were whistled at by a marmot which showed up just a few meters away. That was a perfect day.
Short tour from Gentiana via big couloir in NE face.
Short ascent from Lacula Bucura. Because of fog we hadn't a view of the mountains.
Gentiana hut - Bucura peak - (attempt to Judele peak) - Bucura Lake - Gentiana hut. Had a nice view all around.
Came from Bucura Lake, continued towards Vf. Retezat. Great panorama.
