You can walk the grounds and read the signs even when building interiors are closed. Summer may bring indoor exhibits in the Chinese Laundry and Acting Superintendent’s Office, horse-drawn wagon rides and occasional blacksmith demonstrations. Check the current Yosemite Guide if one of those is the reason you’re coming; the schedule changes.
Parking near the Wawona Store and Pioneer Gift Shop is the best access, with an accessible restroom nearby. The paved approach includes an 8.1% slope, and paths within the center are dirt; there is no designated accessible parking. Pets aren’t allowed for this activity. There’s no separate activity fee, though park entrance fees may apply.
