Leavenworth itself is a wild little place--it's a total replica of a Bavarian village. It's definitely worth strolling around town and checking out the gift shops, tasting rooms, and restaurants.
The retreat center has a lodge with a cozy great room, a meadow for lawn games, easy hiking trails, and a basketball court. The wedding party and our vendors will be buzzing around, hard at work on Saturday, and obviously we'll be convening for the wedding itself, but you should also feel welcome to hang out, crack open a beer, and mingle with friends and family here.
Icicle Ridge is a great day hike that is close to Leavenworth and has nice views at the top. We hiked it with a bunch or friends for Denali's 30th birthday!
