The Mrazek trail is technical and filled with beauty. I love this trail when Phils Trailhead is packed and the weather is nice. It's a good way to escape the crowds and still have some beauty to explore. If you start from the downhill section you will have a good climb ahead of you. If that is not your thing you could shuttle this ride, but the road up to the top is gnarly and will work over any car that does not have a lot of clearance. The trail follows the edge of a canyon that has been created by Tumalo Creek. When you get to the top, the trail becomes a blast and can be technical in a few spots. The upper section is pretty straight and super fast, and the lower section is packed with switchbacks and a bunch of rocky sections. I would not take a beginner on this trail as it's just a little gnarly for someone new to biking. Overall this is a technical trail packed with beauty and a little out of the way from the other popular trails in Bend, which makes it a great way to escape the crowds on a busy day. If you have the time, be sure to check it out!
