The domes are quite an interesting place to spend a few hours.  They are basically interesting rock formations with a slightly other worldly feel to them.  They sit in amongst farming areas and so the view from the top is quite picturesque.  You can climb them without too much difficulty although some caution is needed as it's fairly easy to slip and fall in places (as I managed to prove!).  I would definitely recommend spending a few hours here before walking up to the top of the cascades and (in the wet season when there's enough water) having a cool off dip in the water.

Great Place with a nice view
