The crystalline waves and arboreal shores of Oklahoma's Grand Lake might shine on a postcard, but exploring them in person is another experience entirely. That's why Sail Grand Waterfront and its fleet of high-end rentals are a must for those visiting the area. Nature lovers can skip along the waves atop a jet ski, scream words like "starboard" on a sailboat, or overcome your fear of seaweed while fishing on a bass boat. If bird's eye is your favorite type of view, you can soar as high as 500 feet above the lake during a parasailing experience.
