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.

These five coastal stories reward curiosity. They also show why the photograph and the practical visit need to be considered together.

1. 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.

2. 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 essential correction is that the beach is not a difficult-but-allowed destination: the park states there is no beach or ocean access at McWay Falls.

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.

3. 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.

4. 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.

5. 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.
