Lopez Island is the third largest of the U.S. San Juan Islands, and the first stop of four on the Washington State Ferries' San Juan Islands run. A normal sailing takes about 40 minutes from Anacortes to Lopez. There is a small airstrip on the island with daily commercial flights, and charter floatplanes sometimes land in Fisherman Bay. Lopez Island is 29.81 square miles (77.207 km²) in land area. The 2000 census population was 2,177.
The island is longest in the north-south direction, with the ferry landing at the extreme north end. Near the ferry is Odlin Park, and Spencer Spit State Park is also on the north end. Near the center of the island, south down the coast from Lopez Village, is Shark Reef, another park. On the south-east corner of the island is the large Sperry Peninsula, the former site of Camp Nor'wester, which was purchased in the late 1990s by Paul Allen (a founder of Microsoft) for a private retreat.
Lopez is much flatter than most of the other major San Juan Islands, which makes it a popular destination for bicycle tourists. However, many roads are narrow, leading to occasional congestion and conflicts between car drivers and cyclists. Lopez is locally famous for the longstanding custom of waving at every motorist, bicyclist, or pedestrian encountered on the island's roads.
Lopez, along with Orcas and San Juan, has its own fireworks show every year on July 4th. The show is held at Fisherman Bay.
The Lopez Island Historical Museum collects and preserves the regional history of Lopez and the San Juan Islands. The Museum features artifacts reflecting Lopez's contributions to maritime, fishing and farming. The museum has an extensive archive of documents of local historic, and artifacts depicting late 1800s and early 1900s Lopez life.
Lopez is home to a large number of tourist related businesses, largely country-style bed and breakfasts, many if not most with ocean views. There is a vineyard and one hotel and resort.
