10 Unusual Shorelines: Glowing Water, Black Sand and Sculpted Coasts

An unusual beach often has a story hidden in its colour or shape. Dark sand can point to volcanic rock; a brief blue glow can come from living organisms; a sparkling fragment may reveal a much less romantic history of discarded rubbish.

Ten coastal settings reveal different reasons for an unusual shore, from volcanic material to living light and sea-worn glass. Begin with the five examples discussed in more detail, then compare the complete collection below. Some are places to walk or view from above; others are broad regions containing several different beaches. Knowing what the photograph actually shows is the first step towards choosing a visit that suits you.

Overview: Bioluminescent shores: a living light show

Jervis Bay in New South Wales is associated with sightings of glowing coastal water, but bioluminescence is not an attraction that switches on every evening. It is light produced by living organisms, as NOAA explains, and visibility depends on the organisms and conditions present.

The blue-water images in this archive illustrate the effect; their precise shooting locations have not been independently established. Camera settings can also make the glow appear stronger than it looks to the eye.

Plan to enjoy the coast in daylight, with any evening sighting as a possibility. Do not enter unfamiliar water at night or disturb wildlife to produce a photograph.

Overview: McWay Falls, California: a beach to view from permitted areas

The waterfall and small cove at Julia Pfeiffer Burns State Park make a memorable coastal scene. The park states there is no beach or ocean access at McWay Falls; view the cove from permitted areas.

The official park page also carries changing fire, road and trail restrictions. At this article’s September 2026 check, the park was partially open with active restrictions. Recheck before travelling and use only areas open to visitors.

Overview: Punaluʻu, Hawaiʻi: dark sand and a changing visitor setting

Punaluʻu’s black sand creates a strong contrast with the sea and surrounding vegetation. The colour is part of the island’s volcanic landscape, while resting sea turtles can add another reason to observe the shore quietly.

Give turtles space and keep their route between land and water clear. Do not touch or approach them for a close photograph.

The visitor facilities also require a fresh check: Hawaiʻi County announced the end of its park lease in August 2026. Older claims about county-managed camping, bathrooms or parking should not be assumed to describe current arrangements.

Overview: Mautohe Cathedral Cove, New Zealand: coastal rock is still changing

The arch and surrounding coast near Hahei are shaped by an environment that continues to erode. The Department of Conservation’s track page provides current access and hazard information.

Check the designated route, weather and tide guidance. Do not use an old photograph of visitors beneath a cliff as evidence that standing there is appropriate today. A coastal visit can change after storms even when its most famous landmark still looks familiar.

Overview: Glass Beach, California: beauty with an uncomfortable origin

The rounded glass associated with Fort Bragg’s Glass Beach comes from a history of dumping and the subsequent action of the sea. It is a reminder of human impact, not an example to recreate by adding glass to another beach.

Leave pieces where they are, follow the signs for protected areas and use established access. You do not need to take part of a place home to remember the way it caught the light.

Choose the experience, then check the day

For a broader comparison of coastal outings, explore six different kinds of beach days. If unusual colour is what caught your attention, Japan’s sea-firefly photography offers another story in which living organisms, timing and photographic technique all matter.

Ten Island and Coastal Settings

This collection ranges from named beaches to entire coastal regions. Their unusual appearance comes from different processes: living organisms, volcanic material, erosion, wave action and human history. The photographs are more informative when those causes are kept distinct.

1. Jervis Bay, Australia

The original entry concerns bioluminescent water in the Jervis Bay area. Such displays are intermittent, not a nightly lighting feature available whenever a visitor arrives. The bay’s ordinary daylight coast is part of the destination too; the glowing photograph captures a particular event.

2. McWay Falls and Julia Pfeiffer Burns State Park

At McWay Falls, the waterfall, small cove and surrounding slopes form one coastal composition. Appreciate that relationship from areas California State Parks has opened to visitors. The beach below has no permitted public access, so a picture of its inviting sand should not become a plan for a descent. Before making the drive, check the park's current trail and road notices and choose an alternative coastal stop if the viewing route is unavailable.

3. Algarve, Portugal

The Algarve is a region with varied coastal forms rather than one cave or beach. Arches, cliffs and coves can look similar in photographs while belonging to different places. An old operator name does not establish a current route or departure point for all of them.

4. Cathedral Cove, New Zealand

The arch and adjoining shore make this Coromandel setting recognisable. The relationship between an opening in the rock and the view beyond is the main photographic feature. A historic description of walking routes should not be treated as a live trail-condition report.

5. Anse Source d’Argent, Seychelles

The granite boulders on La Digue divide the shore into smaller visual spaces. Sand, rock and water create the characteristic image together. Travel between Mahé and La Digue involves actual ports and transfers; a ferry does not depart directly from an airport terminal.

6. Punaluʻu and Hawaiʻi’s black-sand shores

The dark sand reflects the island’s volcanic setting. Its colour distinguishes it from coral or pale mineral sands, but does not make every black beach identical. The original turtle photographs should be appreciated without treating resting wildlife as an invitation to approach.

7. Menorca, Spain

Menorca is an island containing many different coves and beaches. The clear-water photographs represent particular locations, not one continuous shore. Choosing the actual cove is more useful than relying on a total beach count that may depend on how small inlets are classified.

8. Bazaruto Archipelago, Mozambique

Bazaruto lies off Mozambique’s coast and includes inhabited islands within an important marine setting. It is not a landscape without people or history. The photographs credit Jody MacDonald and give a glimpse of the islands’ expedition setting. Activities pictured on that journey are not necessarily services offered to every visitor.

9. Zlatni Rat, Croatia

The projecting beach near Bol on Brač is the feature behind the Golden Horn name. Its outline is central to the image. The original single length measurement should not imply a permanently fixed shape or describe conditions along every side of the beach.

10. Glass Beach, California

The rounded glass fragments reflect a history of discarded material being worked by the sea. That history makes the shore unusual without making pollution a model to repeat. Leaving the glass in place helps preserve the feature for future visitors.

Compare the process, not just the colour

Jervis Bay’s glow comes from a living phenomenon, Punaluʻu’s dark material from a volcanic context, and Glass Beach’s fragments from human disposal and later weathering. Cathedral Cove and the Algarve foreground the shaping of rock. These differences give the ten-place collection a useful theme beyond unusual holiday photographs.
