My husband and I always bring our bikes when staying at the Wilderness Lodge. Riding from the Lodge and all over the camp ground is often a highlight of our trip. There are two bike racks for personal bikes. They were up the walk way from the bike barn. Our bikes were often the only two bikes locked to it. I don't know where they moved the bike racks to during the construction. I seem to recall they were on the walkway between the Lodge and the Villas. We have never brought our bikes into the room or left them in the parking lot. We do bring a lock and use that whenever we leave them.
Ride to the campground early in the morning and see all of the deer about on the path.
