As others have said, BE CAREFUL!!!
In sum, there are only 3 places you can turn a jet aeroplane around in the valley so go arounds, eng fail procedures and baulked landing procedures need to be rehearsed until you can do them in your sleep. No faster than 150kias in the valley unless you are a local and know your way around.
ATC very helpful and will advise on most appropriate procedure for the wx also available to talk to on telephone before departure!
