Visit Snoqualmie and Hike to Twin Falls (Transportation included)

Jonny was knowledgable and fun, and timed the hikes perfectly. The meeting place is a block away from the Chinatown light rail station, v easy to get to. You'll get picked up in a van and travel to the locations. Jacket recommended even on warmish days, as the bottom of the falls is quite cool. It gets warmer as you start moving, though. Would recommend shoes with traction as there are some gravelly areas. The hike is easy/moderate but Jonny might hike at a good clip to get the group back to Seattle on time, so keep that in mind. You can choose to go partway and wait for the group or turn around on your own if you're tired; the trail is very straightforward except for maybe one turnoff at a sharp switchback (you can take a photo of the map at the trailhead or find the Twin Falls Trail on Alltrails if you're worried about getting lost). The hike is never exposed, either in terms of heat or a dangerous grade. You're under a canopy the entire time and there are no drop-offs. Appropriate for all levels. Even if you don't hike at all, you'll still get a couple of great views of waterfalls. Great way to spend half a day for all fitness levels!
