In Palau, we did a sea kayak excursion around the rock islands with Sam's
Tours, which was excellent!  Sam's is at the marina in the main town. We did
this for our last day, after diving for a week. A motor boat takes you out
to a nice set of islands, where you get in your kayak and paddle around (no
experience necessary) while the guide shows you caves and sinkholes and bats
and cliff swallow (birds nest soup) nests. Then you snorkel for a while, and
see hard coral in many colors (purple, green, orange, blue, red), the sea
anemone that's really a walking coral head, and odd fishes and snails.

Then we had lunch up on top of an island near an old Japanese pill-box from
WWII (huge piles of saki bottles piled outside) and watched from above as
some local fishermen hunted sea turtles (no flaming please--they're allowed
to hunt).  My husband decided that was enough, so he went back with the half
day trippers, while I stayed for the full day (they even refunded him the
other half day). We did more kayaking to see interesting plants and birds,
then snorkeled in a salt lake in the middle of one of the small islands,
where we saw lots of mandarin fish (very pretty!).  To exit the lake, we
swam thru a short tunnel out to the sea (lowering tide left a small airspace
at the top), past some sleeping reef sharks.

Then the motor boat came to take us home.
