In reply to Mollythedog:
Depends what you want.
Rokt is in brighouse (don't tell the locals its in hudds or you might be burnt at the stake) it has more boldering and more varied angles. The silos are a novelty for top roping and the lead wall is great for training of long routes (21m overhang). Lots of kids groups all day every day so it seems
Huddersfield is better for routes more angles more space, plenty of top ropes good mix of grades from 3/4 to 8a. only problem is the lack of height. I think its 12m and the staff assure me its as high as leeds wall just with out the overhang. The bouldering is well set just limited due to the space. You do not have to sign up to Kirklees active leisure (KAL) to get into the climbing wall but you get a discount if you do. If its a one off visit its probably not worth. You may get the discounted rate if you are a memeber at HCC MCC or RCC but I am not so I don't know.
If its a hit and miss day
Cliff dries out fast and gets the sun from around 1pm. Bouldering some very nice stuff and a good free guide here
