A 1035-acre federally protected nature sanctuary, Hobe Sound has two sections: a small slice on the mainland, opposite the Jonathan Dickinson State Park; and the main refuge grounds at the northern end of Jupiter Island. The Jupiter Island section has 3.5 miles of beach (it's a favorite sea-turtle nesting ground), while the mainland section is a pine scrub forest. In June and July, nighttime turtle-watching walks occur on Tuesdays and Thursdays (reservations necessary), and birding trips can be arranged through the Hawley Education Center at Blowing Rocks Preserve.
