Rainbow Haven Beach Park became a part of the Nova Scotia Lifeguard Service in 1988. Swimmers are advised to stay away from the tidal channel due to strong currents that develop. Beach conditions are recorded daily by lifeguard staff. The lifeguards also post hazard signs in front of areas that are unsafe for swimmers. Rainbow Haven Beach is located 8km east of Cow Bay.
The beach may be reached by turning onto Bissett Road from Portland Street in Cole Harbor. The Provincial Park entrance is the next right after turning left at the end of Bissett Road.
