Coming from Beddgelert (Nant Gwynant), I rode this easy and steady climb up the fairly busy A498. You cycle past the majestic Yr Wyddfa (Snowdon) here and that mountain is always in view. At the top of the pass is a cosy youth hostel where the food and drink is good, and cosy too, with lots of mountain walkers in particular. This region attracts many outdoor sports enthusiasts. The traffic can be annoying, but you certainly shouldn't put up with it, as the ride is great. Alternatively, a (p... read more

Coming from Beddgelert (Nant Gwynant), I rode this easy and steady climb up the fairly busy A498. You cycle past the majestic Yr Wyddfa (Snowdon) here and that mountain is always in view. At the top of the pass is a cosy youth hostel where the food and drink is good, and cosy too, with lots of mountain walkers in particular. This region attracts many outdoor sports enthusiasts. The traffic can be annoying, but you certainly shouldn't put up with it, as the ride is great. Alternatively, a (partly) unpaved road runs along much of the A498. Not easier, but quieter. Drive the route to Pen-y-Pass especially the other way from Llanberis. You sometimes imagine yourself in the Pyrenees here.

Komende vanuit Beddgelert (Nant Gwynant) reed ik deze makkelijke en gelijkmatige klim over de tamelijk drukke A498. Je fietst hier langs de majestueuze Yr Wyddfa (Snowdon) en die berg is dan ook steeds in beeld. Boven op de pas is een gezellige jeugdherberg waar het goed van eten en drinken is, en gezellig ook, met vooral veel bergwandelaars. Deze streek trekt veel buitensporters. De verkeersdrukte kan vervelend zijn, maar je moet het er zeker niet voor laten, want de rit is geweldig. Als alternatief loopt er langs een groot deel van de A498 een (deels) onverharde weg. Niet makkelijker, wel rustiger. Rijd de route naar Pen-y-Pass vooral ook de andere kant op vanuit Llanberis. Je waant je hier soms in de Pyreneeën.
