Ar ddiwrnod braf o haf, roedd y tri ffrindiau—Rhys, Carys, a Gareth—yn barod am antur yng Nghymru.

On a fine summer day, the three friends—Rhys, Carys, and Gareth—were ready for an adventure in Cymru.

Roedd Rhys yn awyddus i'w arwain trwy ei deithiau cerdded gyda chyffro.

Rhys was eager to lead them through his walking routes with excitement.

Roeddent wedi dewis Pontcysyllte Aqueduct, strwythur mawreddog yn uchel uwchben afon dawel.

They had chosen the Pontcysyllte Aqueduct, a magnificent structure high above a tranquil river.

Tra'r oeddent yn cerdded, roedd yr haul yn tywynnu, gan greu golygfa ysblennydd dros y cefn gwlad.

As they walked, the sun was shining, creating a splendid view over the countryside.

Gan gyfeirio ymlaen, roedd Rhys yn teimlo bod yr haul yn gwenu ar ei gynlluniau.

Moving forward, Rhys felt that the sun was smiling on his plans.

Roedd Carys yn dawel, er bod colofnau uchel yr aqueduct yn erbyn ei chalon, ei phryder am uchderau yn cuddio dros ei wyneb.

Carys was quiet, even though the tall columns of the aqueduct were against her heart, her fear of heights hidden over her face.

Yn y cyfamser, roedd Gareth yn chwerthin a cheisio cadw'r awyrgylch yn ysgafn, er bod ei ben-glin yn cynnal cyfrinachau rhyfedd.

Meanwhile, Gareth was laughing and trying to keep the atmosphere light, even though his knee held strange secrets.

Wrth iddynt gyrraedd hanner ffordd, bu newid sydyn.

When they reached halfway, there was a sudden change.

Stopiodd Gareth yn strach ar ei ben-glin.

Gareth stopped in his tracks, clutching his knee.

Roedd y boen yn sydyn ac yn annisgwyl.

The pain was sudden and unexpected.

Dechreuodd Carys gicio gofalu, ond roedd y golygfa o'r uchder yn dal ei llygad, gan ei lapio mewn ofn.

Carys started to fuss over him, but the view from the height held her gaze, wrapping her in fear.

Daeth Rhys i feddwl yn gyflym.

Rhys quickly began to think.

Roedd ei galon yn pwyso wrth ddewis rhwng eu diogelwch a'r antur a gynlluniodd.

His heart weighed heavily as he chose between their safety and the adventure he had planned.

Yn sydyn, edrychodd Rhys i mewn i lygaid ei ffrindiau.

Suddenly, Rhys looked into his friends' eyes.

Roedd eu diogelwch yn hollbwysig.

Their safety was paramount.

Heb flewyn ar dafod, gosododd Rhys ei fag i lawr a thynnodd gyflenwadau brys allan i atgyfnerthu pen-glin Gareth.

Without hesitation, Rhys set his bag down and pulled out emergency supplies to support Gareth's knee.

Gyda chefnogaeth Carys, dechreuon nhw symud yn ôl yn ofalus.

With Carys's support, they began to move back carefully.

Sicrhaodd Rhys ei bod hi'n okay gofalu am ei ffrindiau tra'n cilio oddi ar gadwyn yr aqueduct.

Rhys made sure that it was okay to take care of his friends while retreating from the aqueduct's span.

Ar ôl cyrraedd y terfyn, eisteddodd Gareth a gan ddiolch ei ffrindiau gydag ochenaid o ryddhad.

Once they reached the end, Gareth sat down and thanked his friends with a sigh of relief.

Gwnaeth Carys agor ei chalon i'r ddau, gan sôn am ei phryder mawr am uchder.

Carys opened her heart to the two, mentioning her great anxiety about heights.

Gwnaeth Rhys weld bod gwir gryfder yn yr hyn maen nhw wedi'i gyflawni gyda'i gilydd: cymorth, dealltwriaeth a gofal.

Rhys realized that true strength lay in what they had achieved together: support, understanding, and care.

Dysgodd y gallai llwyddiant gael ei ddarganfod mewn undod a bod gwerth cynnil yng nghariad a gofalu am ffrindiau.

He learned that success could be found in unity and that there was subtle value in loving and caring for friends.

Roeddant yn unedig, yn gryfach nag erioed, yn barod i wynebu eu hymrwymiadau nesaf gyda'i gilydd.

They were united, stronger than ever, ready to face their next commitments together.
