I flew there in 2005. Don't know how it evolved since then.
Access
Entrance via the south-eastern corner of the un-built area on which the take-off lays, via 'Camino Algarrobo Mirasol' (or maybe alternatively via 'Almirante Lynch' (north-western corner of the field)) (115km from Santiago, about 2h10 drive).
Rules
Please respect the neighbours quietness and privacy: don't watch them laying down on their private deck or by their pool!
MAIN ACTIVITIES
paragliding.
Other activities
paratrike.
WEATHER
Be careful flying too much north of the beach if the wind drops: landing in the water can easily kill you!
