The site has undergone extensive improvements, including tree clearing, grass planting, and the installation of bathrooms and artificial turf. A new weather tower provides updates every 5 minutes. The shuttle service has been enhanced to eliminate a 300-yard hike, allowing direct access from the LZ to the launch. The site is flyable with winds from the south, west, and preferably the north. During peak season, Tiger Mountain offers prolific lift for beginner pilots to enjoy hour-long flights, while advanced pilots can explore ample cross-country opportunities. Flights have reached as far north as the Canadian border, south past Mt. Rainier, and east through Snoqualmie Pass. **Soaring and Airspace:** Tiger Mountain is extremely soarable. Most XC pilots work their way up to cloudbase and then fly south to Enumclaw, east towards Mt. Si, or north towards Duval. Due to airspace restrictions and limited LZs, there is little XC potential to the west. Controlled airspace directly over Tiger Mountain is at 5,000 feet, rising to 6,000 feet halfway between the launches and the summit. Commercial jets may fly over Tiger Mountain, so do not break airspace regulations. **Directions to the LZ:** From Seattle, take I-90 east to exit #17, Front Street exit in Issaquah. Head south on Front Street, which turns into Issaquah-Hobart Road. After leaving downtown Issaquah, continue for about 2 miles. The LZ parking and grass field will be on your left. Limited parking is available, with additional paid parking nearby. GPS Coordinates: 47º 30' 01.6"N 122º 01' 19.1"W. **Directions to Launch:** - **Hike:** The Chirico Trail is a moderate 1-hour hike from the LZ to the north and south launches. The trail entrance is on the east side of the LZ. - **Shuttle:** For those who prefer not to hike, the Tiger Shuttle is available.
