This one-story, wooden building is nestled on the edge of a mountain valley lined by conifer forests and jagged mountain peaks. Most visitors enter through a large triangular overhang at the front entrance, which opens into a small 24-hour vestibule. A family, mens', and womens' restroom are located to the left. Two sets of double doors continue straight into the main building. Rangers provide information at an information desk at the right and notify visitors of the start of the 20-minute park film in the auditorium accessed through the doors to the left of the desk. In the center of the main room is a 3-D relief map of the park with buttons that indicate the four types of volcanoes in the park. To the immediate left of the map is a small, L-shaped park store. On the far side of the map is a doorway that opens to the back patio. To the right of the doorway is an interactive sandbox exhibit. The remainder of the rectangular building extends to the left and right of the map. The left wing of the building includes a seating indoor, fireplace, gift shop, cafe, and an exit to a service parking area. The right wing of the building includes a circular exhibit hall and an emergency exit in the far corner. The exhibit area includes an inner circle with volcanology interactive exhibits and an outer circle with text-based natural and cultural history exhibits. Within the outer circle are two smaller free-standing, cylindrical displays featuring interactive exhibits designed for young visitors.

This single-story building is built of native volcanic rock and surrounded by a three-foot-high rock wall. A set of steps leads to the front entrance, which opens into a large exhibit hall. An information desk and is located in the corner to the right and a park store is located in a corner to the left. A set of glass exhibit cases sit in the center of the room creating a circular walkway through exhibits on both sides. A doorway at the back of the hall leads down a short hallway to an auditorium where the park film is shown. The hallway ends at a wheelchair accessible entrance that exits to a ramp that wraps around the building and back to the front entrance. The museum sits on the west edge of a plaza, which includes a small restroom building and a second single story building that serves as a ranger station.

The historic museum is located one mile from the northwest entrance of the park near Manzanita Lake. The museum is only open during the summer months. Visit for information, to view exhibits and the park film, shop at the park store, or participate in a ranger-led program (offered primarily outside in the adjacent Loomis Plaza).
