Washington State white water river rafting on the Wenatchee, Skykomish, Methow, and Skagit rivers outside of Leavenworth and Seattle, Washington. Alpine Adventures has been running whitewater river rafting trips for over 20 years. The closest whitewater rafting to Seattle is on the exciting Class IV-V Skykomish River. Our most popular whitewater rafting fun in the sun is on the Wenatchee River in Leavenworth. There is lots of snow so that means lots of water to make a great 2012 rafting season. The season kicks off the begining of May, trips are available on the Skykomish now. Give us a call locally at (360) 863-6505 for river information, gift certificates, and to book your trip over the phone. No matter what your river fancy may be, Alpine Adventures is here for you.
