One of the nicest spots in SE Florida, especially if you are not attracted by crowds and glitz, is the Loxahatchee National Wildlife Refuge, which is about a half-hour north of FLL (just off Florida's Tpk). There are lots of paths and boardwalk areas (through swamps) to explore and enjoy the wildlife and flora -- really a pleasant spot to get away from the endless chain restaurants, gated communities, and general vulgarity of the 'Gold Coast.'
