At Thunderbird Park you'll find an easy-to-access network of trails in North Phoenix and a moderately challenging hike along the Thunderbird Park 3 Peaks Loop.
This is a great spot to go for a quick run or a short hike if you're in North Phoenix. Thunderbird park is easily accessible with free entry and a number of picnic areas.
There are 3 main hills with a variety of trail options to hike up/around each. From the top you'll find a nice view of valley and the north Phoenix area.
From Glendale head North on 59th Ave past the freeway and into the hills. Turn left after the road singles to one lane, or continue under the bridge between the hills and make a right turn to climb the southern hill. You can also access another trailhead on 67the Ave. from the opposite side. This is a convenient spot for anyone in the Glendale or north Phoenix area.
