Placentia Bay in the context of Cape Shore

The Avalon Peninsula (French: Péninsule d'Avalon) is a large peninsula that makes up the southeast portion of the island of Newfoundland in Canada. It is 9,220.61 square kilometres (3,560.10 sq mi) in size.

The peninsula is home to 270,348 people, about 52% of the province's population, according to the 2016 Canadian census. The peninsula is the location of St. John's, the provincial capital and largest city. It is connected to the main section of the island by the 5 km (3 mi) wide Isthmus of Avalon. The peninsula protrudes into the rich fishing zones near the Grand Banks. Its four major bays (Trinity Bay, Conception Bay, St. Mary's Bay and Placentia Bay) have long been the centre of Newfoundland's fishing industry.

The Burin Peninsula (/ˈbjʊərɪn/ BURE-in) is a peninsula located on the south coast of the island of Newfoundland in the province of Newfoundland and Labrador. Marystown is the largest population centre on the peninsula.

The Burin Peninsula extends to the southwest from the main island of Newfoundland, separating Fortune Bay to the west from Placentia Bay to the east. It measures approximately 130 km (81 mi) in length and between 15 and 30 kilometres (9.3–18.6 mi) in width. It is connected by a 30 km (19 mi) wide isthmus between Terrenceville and Monkstown.

Trinity Bay is a large bay on the northeastern coast of Newfoundland in the Canadian province of Newfoundland and Labrador. The Bay along with Placentia Bay to the southwest define the isthmus of Avalon from which the Avalon Peninsula lies to the east of the main landmass of Newfoundland Island. The maximum depth of the bay is about 580 metres (1,900 ft).

Major fishing communities include Trinity and Heart's Content. The smaller communities in Newfoundland may often be referenced by the Bay in which they are located, e.g.: 'Brownsdale, TB'.

Burin (/ˈbjʊərɪn/ BURE-in) is a town on the Burin Peninsula in Placentia Bay, Newfoundland and Labrador, Canada. The Burin Peninsula is often affectionately nicknamed "The Boot" due to its resemblance to the footwear when seen on a map, with the town of Burin located near the "heel". Burin is approximately 318 km from the capital of St. John's. Settlement in Burin dates to the early 18th century, although documentary evidence indicates that French fishermen had been fishing and exploring the area even earlier.
