Check out Seattle while you're in town! It's about an hour from Arlington. The view at the top of the Needle is amazing.
The town of La Conner is full of history and gorgeous views. It's only 20 minutes away, with minimal traffic. There are some amazing restaurants too!
Take a drive up North I5. Take exit 230 and follow Highway 20 West. Follow the signs to Deception Pass. It has many hikes that you can take or just stop by the state park beaches and enjoy the view of this incredible bridge.
Go shopping! DUH.
Research hikes near Granite Falls WA. Just about 15 to 20 minutes outside of Granite Falls, up Mount Pilchuck there are numerous breathtaking hikes. From easy to difficult. I highly recommend the Mount Pilchuck hike, if you are up for the challenge. Or for an easier hike, check out Monte Cristo or Lime Kilm trail. Remember to stay on the marked path!
A favorite in the Hendry Family! Go check out the old Anderson School House in Bothell, WA. Many different bars and a part of history. You'll be sure to have a fun night out here.
If you enjoy gambling or playing cards, this is a great casino! It's large and very fun! Only 15 minutes away from Arlington.
This gorgeous light house with views of the Puget Sound is located only 30 minutes from Arlington. If you want to take a ride of the ferry it's about $10 for each way.
