Txawm tias qhov siab qis ntawm cov roob no, lawv xav tsis thoob nrog ntau haiv neeg ntawm lawv cov toj roob hauv pes. Cov neeg tuaj ncig tebchaws tuaj yeem ntsib ntawm no sheer bas alt cliffs, pob zeb placers, spectacular waterfalls thiab picturesque gorges. Lub roob Cambrian nyob rau hauv lawv cov tsos yog nyob rau hauv ntau txoj kev reminiscent ntawm Sayan Roob los yog Altai. Tab sis tsuas yog lawv saib me me thiab phooj ywg.

Highest Peak

Plynlimon Vaur yog qhov chaw siab tshaj nyob hauv lub roob Cambrian. Nws qhov siab kawg yog 2467 ko taw lossis 752meters. Lub npe, txhais los ntawm cov lus Welsh, txhais tau tias "tsib peaks".
