Moel Hebog, Moel yr Ogof and Moel Lefn descending through forest.noxibis19/04/2019
8.2 mile circular from middle of 3 roads in Cwm Pennant, followed fairly non-existent path through farmland to access land then ascended through Cwm Llefrith to col, very steep there and back onto Moel Hebog following trail by wall, afterwards followed nice trail over Moel Yr Ogof and Moel Lefn, rocky in places, descended to foot of Y Gyrn into the old mining area west then followed sketchy footpaths through Cwm Pennant back to car. Hot and sunny but quite hazy so could only just make out the outlines of Snowdon, Crib Goch, Cnicht and Moelwyn Mawr but couldn't see much further, a few people about. Earlier that day bagged Moel-Y-Gest in even hazier weather.DanTrig17/04/2019

HF PARTY ON THE RIDGE AND MET A DOE GROUP IN THE FOREST ON THE WAY BACK. GOOD PATH DOWN AND NEW CYCLEWAY GAVE EASY WALKING BACK TO BEDDGELERT.BURGESS18/08/2013
Moel Hebog, Moel yr Ogof, Moel Lefn and unlisted Y Gyrn. Low cloud all day attended by morning intermittent drizzle and afternoon constant drizzle/rai with moderate winds. Too k the edge off what would othrwise probably have been a good walk. Y Gyrn was awkward, tiresome and not worth the effort in this weather. Paths back through forest getting overgrown and one was being diverted.ijpowell15/08/2013
