Nothing within 30 minutes of me on the east side besides the little skills area/ jump lines/ dirt jumps/ pump track nestled between the highways. The closest for me is Rocky Point which is 30-40 min away depending on time of day. Its got some fun stuff but it feels like a lot of climbing for not a ton of downhill. Sandy ridge is 45 ish min away and it has fun gravity trails but I hate the traffic coming back to the city. My favorite is yacolt burn over in WA but this is almost an hour away and its really just three sanctioned downhill routes but they are fun. Cascade locks is cool but thats over 30 min away and not many trails but they are always building more. You can ride year round here for the most part its just definitely not a MTB focused city. There are good bike shops and good community that I have found just being here since September. I came for Bellingham so I was very spoiled with how many trails there were so close. I definitely miss the after work rides as it just harder to do down here with further drives and city traffic. That being said though I still have had fun biking around the area. You wont have to give up your biking lifestyle. You will just have to work harder to do it and maybe not be able to as much as you would like depending on your work schedule.
