...I don't know...is it a massive anticlimax when you get there?
Maybe. I was thinking more along the lines that at both places you'll likely get massively lost and struggle to see any boulders. The new guides should help a bit though.
However, I must admit I've not actually been to Bovey Woods.For scale there are a few videos online:
The Wild Hunt V6,
Aces High V4 and
Black Dogs V2. But there are also a number of routes at these venues - over 30 are listed in the current guidebook (2012) - including three-star sport route
Strongbow (18 metres, 7c) and one of the best outcrop routes in Cornwall
Wild Thing (10 metres, E6 6b). The Pennyloaf was said to be '49 feet by 27 feet with 72 feet girth' so make of that what you will.
What more can I say? Luxulyan's boulders are certainly scattered and hard to find, they'll likely be mossy and somewhat overgrown but
small is one thing they are not.
