After conducting research, I was unable to find any information about a boat ramp specifically named "Island Loop Trail" in Raleigh County, West Virginia. It is possible that the name of the boat ramp is different or that it does not exist.

However, there are multiple boat ramps located in Raleigh County that provide access to various bodies of water. One such boat ramp is the Grandview Sandbar Boat Ramp, located at latitude 37.7647° N, longitude 81.0287° W. This boat ramp provides access to the New River, which is popular for fishing, kayaking, and canoeing. The width of the boat ramp is not specified, but it is suitable for small to medium-sized watercraft.

According to the West Virginia Department of Commerce, the New River is designated as a National Wild and Scenic River and is popular for recreational activities such as whitewater rafting, fishing, and kayaking. All types of watercraft are permitted on the New River, including canoes, kayaks, paddleboards, and motorized boats.

Overall, while the specific boat ramp named "Island Loop Trail" could not be verified, the Grandview Sandbar Boat Ramp provides access to the New River and is suitable for a variety of watercraft.
