In reply to Tuborg:
There are several previous thread on Montserrat, if you're after more information. On the last thread I wrote quite a bit about camping, bivvying and staying the refuges.
Morgan's statement that 90% of the climbing on Montserrat is sport climbing is either very true or very wrong, depending on your viewpoint. What is true is that there are aren't many bolt-free routes on the mountain, almost every route will have some form of fixed protection, and certainly bolted belays. However, there are a fair number of "semi-trad" routes, which basically means trad but with the odd bolt in to protect a tricky bit. More particularly, easier routes tend to have less fixed gear, some of the 5s and 5+s can be very runout indeed.
If you are keen on climbing lower grade stuff (not higher than 5+) then the two best areas for you will be the south-east face (the last chapter in the Cara Sur guidebook) which is almost entirely trad, and has lots of routes up to 10 pitches long; and the Gorros (seperate guidebook), which is less featured and has more bolts.
For mid-higher grade stuff head to the area around Vinya Nova which has several excellent routes between 3-8 pitches, mostly in the 6s and low 7s. The north face is the place to go for the truly impressive steep walls but it will be very very cold in November.
One last point, the style of climbing in Montserrat is very different and the grading is tough. I climb at least a couple of grades lower there than I do on the local limestone.
