Rode LLC over 4 days in April 26. Well crafted route, mostly quiet roads, and occasional gravel/farm track. Amazing views & good signage. One for experienced tourists, given the profile: 4 notable peaks S to N. We lucked out with dry, sunny yet windy conditions: wet weather on the peaks could challenge morale! Route justifies a 34 rear cog, though a 32 would be ok for many. 28mm tyres were fine with 32mm perhaps ideal. A bike-friendly train south from Holyhead at the end!
