Heddiw, yr oedd yr aer yn glir a'r coed yn gorchuddio â lliwiau’r hydref yn Nghymru.

Today, the air was clear, and the trees were covered in the colors of autumn in Cymru.

Roedd Alys, Dafydd, a Rhian yn cyfarfod ar gychwyn eu taith ddringo drwy Barc Cenedlaethol Eryri.

Alys, Dafydd, and Rhian were meeting at the start of their climbing trip through Parc Cenedlaethol Eryri.

Roedd Alys yn llawn brwdfrydedd.

Alys was full of enthusiasm.

Roedd ei bywyd yn y ddinas yn brysur, ac roedd hi’n edrych ymlaen at ymlacio yng nghanol natur.

Her life in the city was busy, and she was looking forward to relaxing in the midst of nature.

Roedd Dafydd, fodd bynnag, yn fwy gofalus.

Dafydd, however, was more cautious.

Nid oedd yn hoff o uchderau ac roedd yn poeni am y tywydd anrhagweladwy.

He wasn't fond of heights and worried about the unpredictable weather.

“Mae cymylau duon uwchben,” meddai Dafydd, gan edrych lan gyda phryder.

"There are dark clouds above," said Dafydd, looking up with concern.

Roedd Rhian, fel arfer, yn dawel a chyfeillgar.

Rhian, as usual, was calm and friendly.

Roedd hi’n mwynhau helpu i gadw pethau’n eglur rhyngddynt.

She enjoyed helping to keep things clear between them.

“Gadewch i ni fynd yn araf, Dafydd.

"Let's take it slow, Dafydd.

Does dim rhaid i ni frysio,” meddai Rhian, gan geisio tawelu ei feddyliau.

We don't have to rush," said Rhian, trying to calm his thoughts.

Wrth iddynt ddringo, roedd y llwybrau'n troelli trwy'r bryniau garw.

As they climbed, the paths twisted through the rugged hills.

Y coed yn cwympo eu dail ar y llwybr, fel eira aur.

The trees shed their leaves on the path, like golden snow.

Roedd Alys yn symud ymlaen gyda’i llygaid disglair, ond roedd Dafydd yn edrych yn sgeptig bob yn ail gam.

Alys moved forward with her bright eyes, but Dafydd looked skeptical every other step.

Pan glywodd y sŵn mellten yn y pellter, roedd Alys yn gwybod ei bod hi am barhau.

When they heard the sound of thunder in the distance, Alys knew she wanted to continue.

“Mae'r sialens yn rhan o'r hwyl,” meddai wrth ei ffrindiau.

"The challenge is part of the fun," she said to her friends.

Ond roedd Dafydd yn oedi, ei ofnau yn rhwystr i’w eglura.

But Dafydd hesitated, his fears a barrier to explain.

Rhian sylweddolodd bod angen cefnogaeth ar Dafydd er mwyn parhau.

Rhian realized that Dafydd needed support to continue.

Gafaelodd yn ei law, gan edrych arno gyda digon o hyder.

She took his hand, looking at him with plenty of confidence.

“Rydym ni i gyd yma gyda'n gilydd.

"We are all here together.

Bydd popeth yn iawn.

Everything will be alright."

”Cerddasant ymlaen, gan ddal at ei gilydd hyd nes iddynt gyrraedd brig mynydd yr oedd son amdano.

They walked on, holding onto each other until they reached the top of the mountain they had heard about.

Roedd y cymylau’n llawn bygythiad, a'r gwynt yn cyflymu.

The clouds were full of threat, and the wind was picking up.

Safai Dafydd wrth droed y dringfa olaf, gan deimlo’r llymaid yn ei stumog.

Dafydd stood at the foot of the final climb, feeling the flutter in his stomach.

Alys gwthiodd ei fraich yn ôl, gan gynnig cefnogaeth.

Alys pushed her arm back, offering support.

“Yr ydym ni i gyd yn gryfach gyda’n gilydd.

"We are all stronger together.

Gallwch wneud hyn.

You can do this."

”Gyda chalon drom, cychwynodd Dafydd gyda phob synnwyr o benderfyniad.

With a heavy heart but every sense of determination, Dafydd started with resolve.

Wrth iddo gyrraedd y copa gyda Alys a Rhian drws nesaf, datgelir golygfa hyfryd o dosturi naturiol.

As he reached the summit with Alys and Rhian by his side, a beautiful view of natural compassion was unveiled.

Roedd cynhesrwydd rhwng y tri ohonynt, fel pelydr yr haul trwy'r cymylau mawr.

There was warmth between the three of them, like the sunbeam through the great clouds.

Wrth iddynt ddechrau'r llwybr i lawr yn ddiogel, roedd Alys yn gwenu, gan ddeall bod y cyfeillgarwch yn werth y byd.

As they began the path down safely, Alys smiled, understanding that friendship was worth the world.

Dysgodd gwerth amynedd a thîm, tra roedd Dafydd yn mwynhau teimlad o gyflawniad.

She learned the value of patience and teamwork, while Dafydd enjoyed a sense of achievement.

Roedd Rhian yn hapus wrth iddi weld ei ffrindiau yn aberthu eu hatgyweiriad.

Rhian was happy to see her friends cherishing their restoration.

Yn eu ffordd eu hunain, roeddent i gyd wedi newid.

In their own way, they had all changed.

Mynd adref, roedd eu calonnau yn ysgafnach, yn barod ar gyfer heriau newydd y gaeaf o flaen.

Going home, their hearts were lighter, ready for the new challenges of the coming winter.
