The humble cranberry gets dressed up for visitors and harvest time in the bogs

“The tall pine trees provided the shade patterns on the floating pinks, reds, and peaches that make up the cranberry harvest,’’ Nauen said, recalling a recent scene. “Tomorrow, with another sunrise, the berries will take on a whole new look.’’

The harvest can often be seen from the side the road; the Cape Cod Cranberry Growers’ Association publishes a harvest route trail guide. But the bogs in their most vivid hues are a short-lived phenomenon.

Fortunately, you need not rely on the whims of Mother Nature or guess the harvest schedule. Venues exist that not only showcase the harvest, but also appeal to history buffs, bird-watchers, foodies, and festival-lovers.

The annual Cranberry Harvest Celebration is one. Held each Columbus Day weekend in Wareham at A.D. Makepeace Co., which sponsors the event with the growers association, the event features juried crafters and activities for children such as “make your own bog.’’ Local chefs put on culinary shows, using cranberries, of course. Last year, almost 20,000 visitors attended.

Makepeace, the world’s largest cranberry grower, has been cultivating cranberries since the 1800s. This fall it will harvest 1,590 of its nearly 2,000 acres. All of its bogs have names, many of them Native American. Wankinco is the largest bog at 75 acres and half-acre Jacoby is one of the smallest.

A highlight of the Harvest Celebration is a continuous display of the three-phase harvesting process of picking, corralling, and loading. Visitors can witness an impressive transformation as 10,000 pounds of cranberries are extracted from the fields over the course of the two-day event.

A machine with “beaters’’ knocks the berries off the vines after water has been added to a dry bog. An internal air chamber causes them to float to the surface, millions of the ripe red berries bobbing in the water.
