This appears to be quite a new facility. The equipment is all very new and excellent quality.
The routes have a good range of difficulty: my 7-y-o son could manage all of the "Family" course (he's good at this stuff); but on the final route of the "sportive" course neither I nor my other children (10 and 13) could make it - it's good to have something that pushes your limits, and to have something that is challenging enough to be beyond the limits of even reaosonably fit and competent people.
When I was there, there were just three staff, and the one doing the briefing didn't speak a great deal of English; it helped that my children and I had been to Go Ape (in the UK) before and the set-up was just the same, otherwise we may not have been able to pick up all we needed to know properly.
One final tip - do NOT follow your Sat Nav to get there unless it's taking you on the TF-24!! We came from the south and my sat-nav tried to take us cross-country from Igueste de Candelaria along a tiny steep mountain road that petered out into a goat track, probably only a mile or two from the destination but still no good...
