Twenty-one Glasgow community members scaled 884-metre Scottish peak The Cobbler on Sunday in aid of the UJIA Ethiopian bar/batmitzvah twinning project.
The ascent includes sections where climbers have to scramble up slopes but despite appalling weather conditions, the group completed the challenge.
Six members of the twinning project - helping to sponsor bar/batmitzvah celebrations for Ethiopians in Israel - were among the participants, led by experienced climbers Steven Banks and Mark Tenby. The main group made it to the official summit and Oliver Levy and David Barnett reached the highest point, known as the eye of the needle.
UJIA co-ordinator Joanna Hyman said it had been "a really great team-building exercise and a chance to meet parents. I think everyone enjoyed it and it was certainly a dramatic climb in parts."
Money raised will go towards one batmitzvah and one barmitzvah celebrant the Glasgow group is sponsoring.
