Holly is an unincorporated community in Kitsap County, Washington, United States. Named in 1895 for the presence of a large holly tree, Holly is located in the southwestern corner of the county, along the Hood Canal.Holly is a residential area, although a substantial number (around half) of residents are summer-only. Holly is known for its isolation, as well as its unusually high rain totals. There are no commercial establishments in the community, as it is accessible only through back roads and is not near any major population centre.

The Dewatto River is a stream in the U.S. state of Washington. It originates in western Kitsap Peninsula and flows south, emptying into Hood Canal.

Octopus Hole Conservation Area is defined as those waters, tidelands, and bedlands of Hood Canal within a line projected due east from the western shore of Hood Canal on latitude 47°27'01"N for 200 yards, thence southerly 628 yards parallel to the high watermark to latitude 47°26'40", thence due west to shore. Similar to the close-by Sund Rock conservation area, Octopus Hole is very popular with scuba divers who enjoy diving the walls associated with the site to view various underwater creatures, including lingcod, giant Pacific octopus, wolf eel, sea cucumber, and nudibranch. The area is well known to regional scuba divers, especially for its two major walls, known colloquially as the north and south walls. These walls have depths of 70 to 80 feet (21 to 24 m), depending upon the tide. Several other walls exist, some going down beyond 100 feet (30 m) in depth. One of these is called "fish pen wall." Additional features include the "fishbowl"—a reef-like area full of life—a large sunken boat just to the north of the north wall and a small wrecked boat between the north and south walls. An alternative method is to access a private beach nearby. Recreational and technical divers alike find Sund Rock attractive for various reasons. Recreational divers appreciate Sund Rock because it is not a current-sensitive area, the main walls are easily within recreational dive limits, and for abundant sea life. Technical divers enjoy the deeper walls and other areas that allow them to dive well beyond recreational limits. Because Octopus Hole is a conservation area, no hunting or gathering of any kind is permitted. Like most sites on the mid to southern Hood canal, this area is not currently sensitive. However, some noticeable current can occur. Such current is not strong enough to significantly affect dive plans or cause problems, but it is strong enough to slow or speed progress, depending upon the diver's direction.

Sund Rock is a designated conservation area on the U.S. state of Washington's Hood Canal. The area is known for abundant and diverse life, including but not limited to Lingcod, Giant Pacific Octopus, Wolf Eel, as well as nudibranch, anemone, and sea cucumber. The area is well known to regional scuba divers, especially for its two major walls, known colloquially as the north and south walls. These walls have depths 70 to 80 feet (21 to 24 m), depending upon the tide. Several other walls exist, some going down beyond 100 feet (30 m) in depth. One of these is called "fish pen wall." Additional features include the "fish bowl"—a reef-like area full of life—a large sunken boat just to the north of the north wall, and a small wrecked boat between the north and south walls.

Technical divers enjoy the deeper walls and other areas that allow them to dive well beyond recreational limits. Because Sund Rock is a conservation area, no hunting or gathering of any kind is permitted. Two ways exist of entering the waters in the area. One option involves a somewhat steep but short hike and surface swim of 250 to 600 metres (820 to 1,970 ft). An alternative method is to access a private beach nearby. The boundaries of the area are

The Duckabush River is located in the Olympic Peninsula in Washington, United States. It rises near Mount Duckabush and Mount Steel in the Olympic Mountains within the Olympic National Park and drains to Hood Canal, an arm of Puget Sound.
