Lehman Caves Visitor Center is the staffed park facility at the end of the main entrance road, about 5.5 miles from Baker. Cave tours check in and leave from here; the building also has an information desk, exhibit hall, park film, store and the Great Basin Cafe. If the cave is your main reason for stopping, reserve ahead: tours are limited to 20 people and often sell out, especially on summer weekends. Arrive about 15 minutes early and check in at least 5 minutes before departure; a late check-in can cost you your ticket.
