Map created by David Cole : Creative for the I-5 Colonnade bike park

I-5 Colonnade is the first ever urban mountain bike skills park. It’s part of a City of Seattle park, but was funded and constructed by the Evergreen Mountain Bike Alliance (formerly Backcountry Bicycle Trails Club). The park features a novice area – the Tqalu Trail; an intermediate and advanced area – Limestone Loop; a dirt jumping section; pump track; trials area and more.
