And how, in place of fish-processing canneries, there now stands a gleaming, state-of-the art aquarium, where Michael is invited to feed the fish. Michael's next stop is Paso de Robles, where he tours the magnificent Hearst Castle, dream home of the newspaper baron William Randolph Hearst, to hear the tale of its creation. Onward to San Luis Obispo and the hills of Morro Bay and Michael joins avocado farmer Jim Shanley, amid his 4,000 avocado trees to harvest the pears and then learn how to make guacamole. Michael's last stop on this leg is outside Santa Barbara at Rancho Camulos, a former cattle ranch owned by a prominent Hispanic family and the setting for a best-selling romantic novel of the 19th century.

Armed with his Appleton's guide to the United States, Michael Portillo arrives in Los Angeles to delight in the 'city of dreams', from its glorious Union Station to its golden beaches and palm-lined boulevards. Like many a Hollywood hopeful before him, Michael heads for the Warner Brothers studio, founded on Sunset Boulevard at the time of his Appleton's, with dreams of stardom ahead. His role as a fearless all-action hero is assured. For the view from the top he takes the Skyslide from the 70th floor of one of LA's tallest buildings before striding out on the Walk of Fame. At the pioneering 19th-century Union Ice company, Michael discovers how Californians have kept their cool. He sees how ice blocks of titanic proportions are made and brings Christmas to LA with a giant snowmaker. Outside the city, Michael heads for San Marino to visit The Huntington, a cultural and research centre with fine libraries, art galleries and more than a dozen botanical gardens. In the cactus garden, Michael discovers more about the founder, nephew of a railroad baron and himself a pioneer of street cars and trolleys. Michael explores the city's latest initiative to break the legendary rush hour gridlock on Los Angeles freeways - a rail link with seven new stations on the LA metro.

Michael Portillo strikes oil in the suburbs of Los Angeles, contemplates his navel in the orange groves of Riverside, makes a California Roll and paints a pretty picture in Laguna Beach. It is Mexican Independence Day and the locals are celebrating the country's hard-won independence from Spain in the early 19th century. There is dancing, singing and feasting in the streets and Michael is up for joining the party. He learns that one in two of the population of LA is Latino, mainly of Mexican descent, and hears after only a few decades, Mexico lost half its territory and California became part of the United States. Michael learns the secrets of backyard oil drilling in Los Angeles, home to the largest urban oil field in the United States. Nodding donkeys are everywhere - in residential neighbourhoods, parking lots and burger joints. Michael sports a zesty orange jacket to visit the Citrus Variety Collection and learns the difference between a pummelo and a papeda. Alongside oil, the citrus fruit industry, he discovers, is one of the bedrocks of the state's economy. At Laguna Beach, Michael learns how artists from the east coast travelled west on the Transcontinental Railroad to found a colony of 'plein air' painters attracted by the beautiful coastline and glorious light to paint outside.

Michael Portillo is nearing the end of his thousand-mile rail journey from Reno, Nevada, to San Diego in southern California. In this final leg, clad in khaki boiler suit and sporting dark glasses, he joins the US Navy Pacific Fleet, birthplace of the elite flying academy Top Gun. Aboard the Pacific Surfliner, he arrives first in the coastal town of La Jolla, where he takes to the water in a kayak to explore the extraordinary 75-million-year-old caves. In San Diego, he picks up the trail of the industrialist and property speculator John D Spreckels, who made the city boom in the 19th century and built a pavilion to house the largest outdoor pipe organ in the world. Michael is offered the chance to play it. Appleton's recommends a trip to a huge structure, completed in 1888, on which San Diegans have depended for water for 130 years - the Sweetwater Dam.

Michael Portillo heads for the last frontier of the United States, armed with his 1899 Appleton’s Guidebook to Alaska.

In Seward, Michael feeds a rescued sea otter pup with a fearsome bite and learns how the luxurious pelts of these endearing creatures were once the most valuable in the world. On a boat trip around Seward Harbour, Michael hears from an indigenous former Alaskan state senator how, shortly before his guidebook was published, the Russian Empire sold Alaska to the United States. Heading north on the Alaska Railroad past lakes and glaciers and through mountain tunnels, Michael learns what it took to build this epic 470-mile line.

Armed with his 1899 Appleton’s Guidebook to Alaska, Michael Portillo rides the Alaska Railroad north to explore the remote former goldrush settlement of Talkeetna. Deep in the forest outside town, Michael gets a taste of the pioneering spirit of early 20th-century prospectors and settlers from a modern day 'homesteader' and helps fell a tree to clear land for a log cabin. From Talkeetna, Michael joins intrepid fellow passengers aboard the Hurricane Turn, the last 'flag stop' train in the United States, waving them off as they alight in the middle of bear country to fish, raft and camp. He continues by rail to admire the snow-capped mountains and glaciers and to cross the gorge on the spectacular Hurricane Gulch Bridge.

Michael Portillo embarks on a second spectacular rail journey through Alaska into Canada on the White Pass and Yukon railway. Arriving in Skagway by seaplane from railwayless Juneau, Michael heads first for Dyea and the Chilkoot trail, which the first gold prospectors hiked 100 years ago to the Klondike. Among them, he discovers, was author Jack London, whose stories of sled dogs captured the spirit of the gold rush. In the puppy pen of a sled dog training camp, a dog musher tells Michael how huskies helped to build Alaska and gives him an insight into how the dogs continue to work and race today. Boarding the 52-mile railway, built in 1898, which climbs 2,600 feet before dropping to the head of Canada’s Lake Bennett, Michael looks forward to beautiful scenery on a railway laden with history. At the lake, Michael meets an indigenous guide to hear of the role of First Nations people in the stampede for gold.

Michael Portillo explores British Columbia, steered by his Appleton’s Guide to Canada, published in 1899. He discovers how two superpowers nearly came to war over a pig and joins the Royal Canadian Navy to firefight on board the frigate HMCS Regina. Starting on Vancouver Island, Michael explores the rich British heritage and colonial past of the provincial capital of British Columbia, Victoria.

This magnificent journey takes him to the highest point of the 19th-century transcontinental Canadian Pacific Railway line at Kicking Horse Pass, past Lake Louise and inside spiral tunnels blasted through the mountains. Along the way, Michael hears of the harsh and dangerous conditions endured by the Chinese and European labourers who built the railway. He looks back at the historic driving of the Last Spike, which completed the Canadian Pacific Railway in 1885. Reaching Banff, Michael follows his Appleton’s guide to the luxurious Banff Spring Hotel, built by the railway company. By Sulphur Mountain, he explores an underground hot spring discovered by railway workers in 1883 and learns how it prompted the creation of Canada’s first national park.

Michael Portillo begins a new journey on the tracks of the Ocean line to explore Canada’s maritime provinces en route to Quebec City. Clutching his 1899 Appleton’s Guide to Canada, he begins in the Atlantic port of Halifax, Nova Scotia, where he discovers an 18th-century British hilltop citadel, manned at the time of his guide by the 78th Highland Regiment. Michael joins the men who recreate the roles of those Scottish soldiers today. At the mercy of the young 'sergeant major', Michael learns the drill in kilt and sporran. Michael follows his Appleton’s to a vast Victorian dry dock, still in use today by shipbuilders for the Royal Canadian Navy and finds out what it takes to build a state-of-the-art Arctic Patrol vessel.

Taking to the skies in a seaplane, Michael flies over the Laurentian Mountains to land on an isolated lake, where he fishes for trout for his supper.

Steered by his 1899 Appleton’s Guide, Michael Portillo strikes west across Manitoba into the province of Saskatchewan. High above the prairie at Riding Mountain, Michael discovers how a middle-class British boy from Hastings transformed himself into an influential indigenous naturalist called Grey Owl. Deep in the prairie, Michael finds a network of railways that once served the wheat farmers of Saskatchewan and learns how communities grew up around the grain elevators used to load the crop on to rail wagons. The Wheatland Express welcomes a new recruit to the sidings on the afternoon shift. At Manitou Beach, Michael reaches the Dead Sea of Canada, a 14-mile lake three times saltier than the ocean. A Yellow Quill First Nations elder tells Michael about the healing properties of the water, and Michael tries it for himself.

Michael Portillo continues west through the Canadian Prairie on his thousand-mile rail journey from Winnipeg, Manitoba, to Jasper, Alberta. Following his 1899 Appleton’s guide, Michael explores a glossy, glassy, oil-rich Edmonton, second city of Alberta. On the banks of the North Saskatchewan River, he travels three centuries back in time to experience the life of les voyageurs, who travelled huge distances within Canada by foot and canoe to trade fur with indigenous people. Michael admires Edmonton’s early 20th-century heritage streetcars, preserved by the Radial Railway Society, and seizes the chance to drive one across a spectacular high-level bridge over the North Saskatchewan River.
