This unique state park dedicated to equestrians contains over 20 miles of horse trails as well as featuring multiple arenas for horse events. The trails are beautiful and heavily forested, a little haven of deep woods in the middle of suburbia.
Also, the park owns a small property across 132nd Ave NE which runs along the east edge of the park, where there are some trail-competition-style obstacles to try your horse with. To find it, cross 132nd near its intersection with NE 51st Place and go north a few hundred feet; there are signs designating the area as part of Bridle Trails Park.
The Bridle Crest Trail along NE 60th Street links this park to Marymoor Park and the Sammamish River Trail with some brief road riding as well as a couple of major road crossings, though recently this trail has been disrupted by construction and route changes at the Marymoor Park end.

Prior to the 1930's the land that is now Bridle Trails Park was
owned by the Department of Natural Resources. Residents demanded
that the state lease it for parkland rather than risk it being sold,
and in the 1960's the state finally purchased it outright for use as
an equestrian park.
