Bass Lake: About 3 miles along Coast Trail, an unmarked trail on the left (only about 0.1 miles long) takes you to Bass Lake (Yelp Reviews). You are allowed to swim in this lake. In July 2010, the water was warm. Inflatable rafts would be fun.
Scrambling: About 4 miles along Coast Trail, there is an unmaintained trail towards Alamere Falls. The final descent to the beach requires a scramble, which I felt was dangerous at one point. The last time I visited (in 2012), there was a rope available to help those scrambling down. With the rope, it felt quite safe. If you choose not to scramble down, you may enjoy a smallish waterfall right before the scramble, which makes the trip worthwhile.
Poison Oak: Yelp reviews for Alamere Falls warn against poison oak. The last two times I visited (in 2010 and 2012), poison oak was not a problem at all. The trail leading down to Alamere Falls felt quite safe and well maintained.
