Excellent! That is a nice intermediate (for hiking) location and close to amenities such as a grocery and the Park Cafe.
A path beside the hiker-biker site in Loop A will take you across a bridge to the Visitors Center. It's about a 5-minute walk (I carry bear spray), as opposed to driving around a longer route. The rangers at the permitting/info desk inside can help suggest backpacking routes.
The campground has a shower block in Loop C.
Have a wonderful time!
