We biked it last weekend , set off up the llanberis path at 6.30am, then back down the rangers and telegraph valley. We were in Pete’s eats for just after 10.
Incedentally, we thought the rangers and telegraph valley was a bit rubbish, too boring. Llanberis path a much better ride down. I’m aware that opinion flies in the face of popular view, but we generally thought it wasn’t worth the climb up.
