Go in the early evening to see all of Palm Beach out walking their fluffy white dogs! Beautiful sunset views over the intracoastal. Watch for dolphins, manatees, and exotic birds. No roads to cross for miles, so you can walk, run, bike, skate--whatever! And the Lantana Nature Preserve is half a block away also.
Only negative: no garbage cans the entire length! Take you trash with you, or look for a can in the parking lots of some of the ungated condos.
