Tiger Mountain, Mountain peak in Washington, US.

Tiger Mountain is a mountain in the Issaquah Alps of King County, Washington, with six peaks forming a 13,500-acre triangle between Interstate 90, Issaquah-Hobart Road and State Route 18. Most of it lies within Tiger Mountain State Forest, established in 1981. A popular 6.2-mile round-trip trail climbs about 2,000 feet to the bald summit of West Tiger #3, overlooking Seattle.

The area experienced logging operations in the 1920s, when timber companies laid railroad grades through the forest. These old routes were later transformed into hiking trails that form the backbone of the current trail system.

Poo Poo Point takes its name from the steam whistles loggers used to signal along the mountainside. Since the 1990s the bare ridge has been a launch site for hang gliders and paragliders, and the Northwest Paragliding Club, formed in 1990, made the first improvements to the north launch in 1991.

Most visitors start at one of the main entry points and follow well-marked paths through the woodland. Weather can change quickly, so proper gear is important, especially during wetter months.

Poo Poo Point's name comes from the steam whistles loggers used to signal along the mountainside. The bare ridge, a Weyerhaeuser logging clear-cut until the 1970s, became a launch site in the 1990s; the Northwest Paragliding Club formed in 1990 and Team Chirico levelled the north launch in 1991. Cross-country flights from here have exceeded 75 miles.
