Four useful lenses

Choose by the experience you want

The right answer depends on the shape of the day. These four lenses make the tradeoffs visible before a reservation or drive.

01

What they are

Clear or pale quartz pebbles, often rounded and polished by natural movement.

02

Where people look

Sunset Beach is closely associated with them. Conditions and beach rules matter.

03

How to identify them

Look for translucence and a glassy quality when wet. Not every pale stone is quartz.

04

What to do with one

Keep a modest souvenir where permitted, or have a piece polished by a local shop.

Local perspective

Let geography do part of the planning

Cape May City is compact, but the larger Cape May area is not one walkable neighborhood. The oceanfront, historic center, harbor, West Cape May, Cape May Point, North Cape May, and county attractions each create a different route.

Group stops that belong together. Walk within the central city. Save the car for the Point, Delaware Bay, airport, ferry, farms, and county destinations. A calm route leaves more time for the reason you came.
