Established around 1859, the community was originally called "Klickitat Landing". The first European settler was Egbert French, who arrived from Ohio. In 1866, French sold his holdings to James O. Lyle from The Dalles, Oregon, who moved to the north bank of the Columbia River.
A post office was soon established with Lyle as the first postmaster, and with mail delivered by steamer from the opposite shore. Steamboat operation lasted until the North Shore Railroad was completed. When the Spokane, Portland and Seattle Railway came to town in 1907, its line passed somewhat north of the town. The present townsite was plotted in 1909, and the older townsite became known as "downtown". In 1941 there was a small airport in Lyle.
Lyle has two main areas: that part which is built on the north bank of the Columbia River, including the downtown, and that part which is built on the hills above the river. The downtown area has one grocery store (which is a super-sized quick-mart), two churches, a museum, a tavern, a restaurant/cafe, a gas station and vehicle repair shop, a second-hand store, an espresso stand, and a historic hotel with restaurant and bar. Other small businesses come and go, and all are located in the downtown area.
Residential areas flank downtown and extend east and west. Newer residences have sprung up on the northern hill overlooking downtown, with row upon row of homes on terraces. Less than 30 years ago, there were fewer than half a dozen homes on the entire hill. Now there are dozens, all seemingly vying for the best view of the Columbia River. Prices for hillside property are high for such a small town, and are based primarily on the view.
The Lyle Community Schools Campus includes three independent, small, rural schools: the area's elementary, middle school and high school, which incorporate students from Dallesport and Murdock. (6 miles (10 km) east of Lyle) The campus is located at the northernmost part of town, high on the hill overlooking Lyle. The student body is small and combines with nearby towns to make up teams for some sports.
Although tiny, somewhat rustic, and usually quiet, Lyle has attracted some attention because it lies very near several popular windsurfing beaches, including Doug's Beach. The area is also home to six boutique wineries: Cor Cellars, Domaine Pouillon, Jacob Williams Winery, Klickitat Canyon Winery, Tetrahedron Wines and Syncline.
Lyle is located in southwestern Klickitat County at  on the north side of the Columbia River where it is joined by the Klickitat River. State Route 14 passes through the town, leading 8 miles (13 km) east to Dallesport and a junction with U.S. Route 197, and 11 miles (18 km) west to White Salmon. Dallesport and White Salmon are the locations of the closest road crossings of the Columbia River to the east and west, respectively. In addition, State Route 142 travels from Lyle to Goldendale along the Klickitat River.(45.695845, -121.282279),
