Oleta River State Park in Miami, FL 33160

Oleta River State Park is a 1043 acre park, the largest urban park in the state, smack dab in the middle of North Miami. Located on Biscayne Bay, with the Oleta River coursing through it, this is a real find. Many different animal species call the park, with its mangrove lined shores, home, including lots of water birds, fox, possum, raccoons, and the endangered West Indian manatee. Outdoor adventurers can definitely find something to their liking. The bike trails are some of the best in the area, with 10 miles of challenging and intermediate trails, four miles of novice trails, and three miles of paved trails. The paved trails are also terrific for rollerblading. If you forget your bikes or helmet, you can rent the bikes at the concession stand for $12-$25 per hour and borrow a helmet. Canoeing and kayaking are also popular activities in this park. Choose from the river or Biscayne Bay for a water adventure. Canoes and kayaks can also be rented at the concession stand for $12-$17 per hour or $25-$35 per day. Picnic areas abound and pavilions can be reserved in advance (in person) for $107 (small, up to 75 people) to $160.50 (up to 150 people) if you want to plan an outdoor recreation party. A sandy beach and fishing pier face Biscayne Bay. Picnic areas have grills, so you can cook up your fresh catch. Swimming is permitted in the Bay, and the man-made swimming area has little surf so it's great for little ones. A boat ramp, and camping facilities are available, too. 14 very simple log cabins are available for rent. Make your reservations early; they book up fast. Only youth groups or non-profit can rent camping facilities. Kids can join the Junior Ranger program at this park. Simply ask for the information at the entrance gate; your kids complete the activities (conservation related information), then return their completed package and receive a badge. This is a great way to promote ecology and responsibility, if your kids are into that sort of thing.
