In reply to Mctommyd:
The majority of easier problems are at the Car Park boulders. As others have said, get hold of the Yorkshire Grit Guide. It covers Brimham well and will give you so many opportunities for the future.
Brimham has a high proportion of rounded top-outs compared to your average gritstone venue. This can be unnerving at first, especially if coming from climbing indoors. Stick with it. It gets easier over time.
Also, conditions are a factor. Cold and dry conditions will give so much more grip (both hands and feet) than warm and muggy weather.
Take it steady, stick with it and you'll be amazed at how well your footwork will improve over time.
