The term "lower mainland" can have different interpretations; for some people it is equivalent to a "Greater Vancouver", while others would include everything out to Abbotsford or even Hope in the East. Here, we use it to describe the area from Vancouver in the west to Hope in the East, and from the American border to the South, to the town of Whistler and the Sunshine Coast to the North.
This area is home to Greater Vancouver, the largest metropolitan area west of Toronto. It is also home to the mainly agricultural Fraser Valley and the outdoor playground of the Whistler environs.
The de facto language is English, though you may be able to find official services in French. Chinese (mostly Cantonese) speakers can also be found relatively easily; Cantonese is the second most-spoken language in the region.
Vancouver International Airport, or YVR as locals sometimes refer to it, is located in Richmond. It serves as the hub airport for Western Canada with frequent flights to other points in British Columbia, major cities across Canada and the United States, Asia and several to Europe . There are a number of ways to get to various Lower Mainland towns from YVR. For more on this airport see "Vancouver International Airport" in the Vancouver article.
There are floatplane facilities located both in the Coal Harbour area of downtown Vancouver (CXH) and at Vancouver International's South Terminal. Floatplanes operated by Harbour Air, Baxter Aviation, Salt Spring Air and West Coast Air fly frequently from downtown Vancouver and/or YVR to Victoria's Inner Harbour, Vancouver Island, the scenic Gulf Islands, Seattle and other local destinations. Finally, Helijet operates helicopter service from the downtown heliport next to Waterfront Station, providing quick and convenient connections to Victoria and YVR. For more on these options see "Floatplane and heliport" in the Vancouver article.
Abbotsford International Airport (YXX), located about 80 km east of Vancouver in Abbotsford, is Vancouver's alternate airport. It handles mostly domestic flights and, with an arranged ride, you can be in and out of this airport in under 10 minutes (with no checked in baggage).
Flying in and out of Seattle-Tacoma International Airport, most notably for US destinations, and then using the bus for travel to and from Vancouver city is an often less expensive option than buying a direct flight from YVR or YXX due to tariffs and "other" reasons. However depending on your nationality, a US visa may be required and could take some time to procure. For budget travellers, you may wish to consider checking flights to and from Seattle-Tacoma International Airport. The bus or train ride takes about 5 hours one way and driving time is approximately 2.5 to 3 hours.
Visitors travelling to Vancouver by car across the U.S. border should be aware that there are often lengthy lineups at the border, in either direction. During summer, waits at the border can exceed three hours during peak times.
Inform yourself about the waits, and you can either delay your crossing until the lines subside, or choose the quickest crossing, or at least set your expectations. You can see official wait time forecasts for both directions on the Canada Border Services Agency website, and for US-bound traffic on the US Customs and Border Protection website. It can be helpful to view webcams of the border lineups; Canada-bound on I-5  and US-bound at most crossings. Two AM stations give regular updates on border lineups in both directions: News 1130 (1130 on the AM dial) every 10 minutes beginning at one minute past the hour, and AM 730 every 10-15 minutes.
The Nexus Land program lets travellers who fill out an application and pass a security check use express lanes through US-Canada land borders by presenting a Nexus card. However, you may only use the express lanes if everyone in your car has a Nexus card. There are also Nexus programs for air and marine travel.
The Lower Mainland, especially Vancouver is well served by bus service. There are a number of different bus lines providing service to various cities near and far. Here are a couple of examples:
Unlikely to be the cheapest option, but travelling from Edmonton or Jasper by rail makes for a good way to see the Canadian Rockies. VIA Rail  has the Canadian which runs from Toronto to Vancouver with 3 weekly departures. Rocky Mountaineer Vacations also operates trains to Whistler, Banff, and Jasper from April to October.
Amtrak  runs a service between Seattle and Vancouver called Amtrak Cascades . Trains depart Seattle daily at 7:40AM and 6:40PM, arriving in Vancouver at 11:35AM and 10:45PM respectively. The return trips leave Vancouver at 6:40AM and 5:45PM.
There are two ferry terminals serviced by BC Ferries in the Lower Mainland.
Both terminals are far enough from the city core that you will need to travel by car, taxi or bus to get into any regional city from them (and vice-versa). In terms of bus transportation, the various coach services are easier to use than public transit. Public buses to and from the ferry terminals is focused on travelers going to and from downtown Vancouver; reaching other destinations may be time-consuming and frustrating.
Depending on how much you want to see, there may be a number of ways to get around the Lower Mainland. Within Vancouver and many of its suburbs, the Translink public transit system can get you to most places. Regional bus companies can take you further afield to places like Whistler and the Sunshine Coast. Vancouver is the hub for these services.
The most convenient means of getting around the region is by car. Highway 1 (the Trans-Canada highway or "Upper Levels") is the main thoroughfare, providing freeway travel through Vancouver's suburbs into the Fraser Valley and the interior of BC. Highway 99 connects Vancouver with the US border to the south and Whistler to the north. Car rentals are readily available throughout the region.
A number of small airlines operate float planes from Vancouver to the Sunshine Coast and Whistler. These are more expensive than other options, but are faster and more scenic.
Some parts of the Lower Mainland (Sunshine Coast and Bowen Island) can only be accessed by boat. BC Ferries provides ferry services to these areas and visitors can walk on or take their car.
