We will meet at 3:00pm at the Eastgate Park and Ride, 14200 SE Eastgate Way, Bellevue, WA 98007-6492, which accessed from exit 11 off I-90. Parking at the Eastgate Park and Ride is free. 

Please rendezvous at Bay 2 at 3:00pm. A map of the layout of the Eastgate Park and Ride is available online here. 

We will then make any carpool arrangements to drive to the Twin Falls trailhead.

If you are not going to carpool and would prefer to meet at the trailhead: please be at the trailhead ready to hike at 3:45pm, and we’ll be starting as punctually as possible, no later than 4:00pm.

The Twin Falls trailhead is located in North Bend, on SE 159th Street, ZIP code 98045.

Directions to the trailhead: Take I-90 to exit 34. Turn right (south) at the end of the exit ramp, and proceed a little more than half a mile to SE 159th Street. Continue another half mile to the Twin Falls trailhead.

This will be a beginner-friendly, scenic, and leisurely hike to soak in some late afternoon sunshine and enjoy some great views. Please do not wear any cotton clothes and practice good hiking etiquette by bringing your headlamp even though we should have plenty of time before sunset occurs at 7:06pm. Read about Ollallie State Park and its history at its website here.

A Discover Pass is required to park at the Twin Falls trailhead. Olallie State Park is equipped with an automated pay station for visitors to purchase a one-day or annual Discover Pass. Information about where else you can buy a Discover Pass is available online here.

I'm sure everyone is aware of the danger posed by wildfires this year. Please be aware that as of early September 2017, the Commissioner of Public Lands has issued a statewide burn ban that applies to state forests, state parks and forestlands protected by the Washington State Department of Natural Resources. Washington state parks are under a Level 4 Extreme fire ban. All outdoor burning, including campfires in fire pits and the use of charcoal briquettes are prohibited at all Washington state parks. Parks under a Level 4 ban may allow liquid or propane camp stoves that do not use solid briquettes and have on/off controls. Be aware that some parks may have a complete ban on any kind of campfire or open flame. To find out the burn ban level at a specific park, please read the burn ban announcement online here.
