A fairly steep climb of a mile at an average of 9%

A long a fairly tough climb on the little road through Dyfi Forest from Aberllefenni until you reach the A487 near the Cross Foxes junction. This follows NCN route 8.
The surface isn't great and it's narrow so best as a climb rather than a fast descent.
Very pretty though and quiet.

Slightly more forgiving as compared to the other side of Aberangell.

Very steep with many signs warning you of that, especially the last challenging climb to the summit where you can appreciate great views.

True slog definition. A climb you won't appreciate - especially after a long day in the saddle.

Just under 2km in length, this climb averages 8% but towards the top ratchets up to well over 10% to maximise the suffering

Very difficult climb - steep throughout, and in some places the legs and lungs will be begging for a break. That break comes with the need to go through a gate - something you won't have to worry about when you conquer the Cambrian Coast Sportive - and then another challenging finale past the yellow bin and waiting for you with coastal views towards Barmouth and the tranquility of Cregennen lakes.

This serene lane offers a fantastic, tarmac-surfaced ride through Happy Valley alongside Afon Dyffryn-gwyn. This entire segment is a climb but it’s fairly steady and gentle, with stunning views of the hills and mountains on either side. A mixture of woodlands, farmland and open hillsides make for rather bucolic landscapes.

While not traffic-free, there’s very little traffic on this road as it mainly serves farms with a more major road running parallel to the south.

A few gates marking farm boundaries give this road its name. A single track with good tarmac and beautiful views. At one point we saw a waterfall on the left and the road rising up like a ribbon to the right. All surrounded by mountains. Perfect riding.

The B4391 between Llan Ffestiniog and the A4212 is a pretty road that rises and falls over moorland and through some woodland. It's a main road but narrow and fairly quiet with lots of impressive scenery to look at.

Hop over the gate and enjoy the views

8km at a 4% average gradient.... however, there are much steeper sections upwards of 13% through the trees and past the stone wall. Strava segment is called 'Llanwchllyn'.

If your ride allows it, make a detour to the Llyn Stwlan Reservoir for the stunning series of hairpins leading up to the reservoir edge

Number 91 on Top 100 Climbs...

Ffordd Pen Llech is the steepest road in the world. The record was award in 2019. Unfortunately it's not possible to climb the hill up to the castle legally, it's a one way road going down to Harlech station.
