There are a LOT of great places to hike that are close to Seattle. One of them is located in the Olallie State Park, about 30-35 miles outside of Seattle – the Twin Falls Trail.
Some waterfalls tend to dry up in the winter time, and come to life again in the spring, as the snow melts in the mountains. Not Twin Falls – it runs year round due to the large amount of rain that falls there (twice as much as in Seattle, which isn’t know for its dryness!).
It has the added advantage this time of year of not being buried under too much snow to be safe.
The hike to Twin Falls from the trailhead is 3 miles, with an elevation gain of only about 500 feet, so it is not a difficult hike.
If you DO want to hike more than that, it intersects the John Wayne Pioneer Trail at the top. Many people who reach this area do not know where they are, but this trail has a 108 mile section from Cedar Falls to the Idaho border, following the Chicago-Milwaukee-St. Paul-Pacific Railroad roadbed. This part of the trail is also called the Iron Horse State Park trail.
The John Wayne Pioneer Trail is open to hikers, mountain bikers, and horseback riders.
The trail is fairly flat for the first 7/10 of the trail as it follows the Snoqualmie River. Then it follows some long switchbacks until it reaches a small trail that descends to a great overlook of the lower falls, a 150-ft drop. You can continue on up for some views of the upper falls.
You can bring your dogs with you on this hike, as long as they are on a leash. Parking is somewhat limited, and it is pretty crowded in the summer, so it is better to plan a visit during the week rather than weekends.
You will need a Discover Pass.
