Black Butte Stables is onsite at Black Butte Ranch. We love going on a trail ride with them and try to stop in every time we are in town. They have easy rides for beginners or more intermediate trails for an experienced group. Both are a blast and we always have a great time.
Shopping in Downtown Sisters is an adventure in its own right, with so many cute boutiques and shops to explore, I guarantee you can't see all the shops in just one trip!
For the adventurer at heart, Skylight Cave is an incredible sight, about 30 minutes from Sisters Oregon. It is not the easiest to get to and as is the case with any cave a bat encounter is likely. Check out the link for detailed directions, safety tips and additional details BEFORE you visit.
The McKenzie River Rafting trip site is about an hour from Sisters, OR and is a great option for a 1/2 day rafting trip. They boast of an awesome adventure cascading through a canyon blanketed in Douglas fir and old growth forest, down the crystal clear river with an abundance of dancing rapids. Call for scheduling, details and cost.
Check out the Recreation/Activities page of the Sisters County website, lots of great recommendations.
Bend is an easy 30 minute drive from Sisters and has its own long list of things to do. Check out the Visit Bend website for just a few fun activity options.
Great place to start if fly fishing or guided fishing trips are on your agenda while you are in town.
