“Sisters on the Fly” is the largest outdoor women’s group in the United States.

Since its start up in 1999, more than 8,500 women have joined the SOTF ranks.  Our current active membership is in excess of 3,600 and growing daily. This membership-based community supports women in their journey to get up, get out and become more adventurous!

Our membership is $70 a year and grants you access to an organized network of incredible members and a members-only calendar of amazing events that take place across the country all year long.

Member-hosted events and special destination trips run the gamut from camping to fishing, hiking, horseback riding, wine tasting, line dancing and whatever else sounds like fun to our members! From gathering for a 1/2 day or several, the sky is the limit for how Sisters recreate together.11.Big SOTF group in Whitefish MT

Once you’ve registered, joined & logged in you will see your official Sister Number (yours for life) in your profile. Also, you will soon get a one-on-one welcome from your area Wrangler. A welcome package with your official SOTF certificate, membership certificate, annual SOTF patch and other SOTF goodies will be in the mail for you in the near future- be patient!

Any woman 21 years or older can join. A Sister on the Fly does not need to own a trailer, have any special or particular skills or know anyone else in the group to be included in the organization’s adventures.

There is one rule for our Sisters on the Fly events and outings: “No Men, No Kids, Be Nice, Have Fun!”
