Tried the Llyn Brenig loop last month, what a hidden gem! Breathtaking views and quiet roads. Looking forward to exploring more of these lesser-known routes.

Top tip for tackling these hidden gems? Check your gear ratios before setting off; some of these routes have climbs that'll make your granny gears whimper!

I must admit, I'm surprised to see the Coed y Brenin route missing from this list. It's certainly popular, but offers some truly hidden gems once you know where to look. Might it have been overlooked?

Having cycled all seven of these routes, I'd recommend taking the Llyn Brianne descent in reverse for an even more exhilarating ride.

I've ridden Lon Las and Traws Eryri, but I must admit I hadn't heard of these 'hidden gems'. Are they well-signposted? I'd hate to miss them!

Just discovered the Mawddach Trail on your list. What a hidden gem! Perfect for a weekend ride from Dolgellau.

Loved your hidden gems round-up! Always thought the Lon Las was enough till I tried the Cwmorthin Trail. What a revelation!

Just returned from cycling in Wales & loved it! Hadn't heard of the Lon Las before, was it as good as they say?
