You should pay the fee to visit. Plenty of signs and information to get here but no mention of a fee. £1 per person, £1 per car, 50p per child.... at this point we stopped reading as we don't carry cash. Woman came from the house to make sure we didn't slip in. Fully understand that it's private land and you have to pay to enjoy it. Just wish we'd known before we set off.

One of the bigger open road passes on Snowdonia. Pretty straightforward from the Penmachno side, once you've crossed the bridge the climb begins in earnest, then it's steep ramps on and off to the top. The little house at the top of the valley is probably 2/3rds to the top of the climb

A beautiful gorge, accessible via a short hike from the landowners' parking lot. The fee is £1 per person plus £1 for parking. You can drop your money into a box, and upon our arrival, an elderly lady with crutches appeared and offered change. The gorge is truly worth seeing. Even if you continue hiking along the river, you'll discover wonderful places to linger.

A good walk or ride. Easily achievable on a cheap MTB or a gravel bike. It's mostly gravel, which makes it a good all-weather route.

Such a beautiful and famous tea house. I'm so glad i got to see it before all the plantation had been removed. Saw in a news feed this week, it lost so much of its character

This bridge across the 900-acre (364 ha) Alwen Reservoir enables a beautiful and tranquil loop of the Wales' largest artificial lake. The views across the water and to the surrounding woodland and hills are lovely.
