This is from Cayce's website and then I will add my own experiences below this.
The Cayce Riverwalk opens the Congaree River for walking, jogging, bicycling, and just gazing at the natural beauty. Its bridges, boardwalks, overlooks, and lighted central path will accommodate all levels of physical access. Its design evokes the natural quality and echoes the first riverfront settlement of 1750's Granby. You can fish for Striped Bass in the Congaree or watch for eagles in the towering pines. It is a place of wonder in the heart of Cayce. You can walk the two and a half miles to old Cayce or linger in the over 46 acres of river park. Historical markers have been placed throughout the park to provide visitors with the background of the area.

My take: The Riverwalk in Cayce holds multiple meanings to me that I will share in hopes that others will want to make their own beautiful memories there.
One, the AWESOME amphitheater, the amphitheater is where the Gervais Bridge starts on the (West Columbia side) and where I attend a community Easter Sunrise service each year with several different churches/denominations in the area .... verbally hearing God's word, knowing that He died on the cross for me, listening and watching the water flow down the river, waiting for the sun to appear over the horizon, and the movement of all God's creatures ... it is "BREATHTAKING".
Two, it is a peaceful place to take a stroll by yourself or with someone, relax, and enjoy the surroundings. The view from the Riverwalk to down town Columbia is awesome. Columbia is not a "big" city by any stretch of the imagination, but on a beautiful clear day, I just find myself just viewing the skyline, admiring some of the old buildings, new buildings, and all the sights and sounds that grab my attention.
If you are ever in the area, it is worth a few minutes of your time to just walk, explore, and enjoy. read more
