What term describes the rights of access such as beach rights?

The correct term for the rights of access to bodies of water, such as beaches, is littoral rights. These rights pertain specifically to properties that are adjacent to oceans, seas, or large lakes. Littoral rights allow property owners to enjoy the use of the water's edge and to have access to the water for various recreational purposes.

In contrast, riparian rights refer to the rights of landowners whose property abuts rivers or streams, focusing on rights associated with flowing water. Appurtenances describe rights or privileges that are attached to a piece of property and typically transfer with the property, but this term is broader and does not specifically refer to water access. Mineral rights pertain to the ownership and use of subterranean resources and are unrelated to water access or use. Thus, littoral rights is the most precise term for the rights of access associated with beaches and similar waterfront properties.
