opening hours
Vesuvius National Park has no single park-wide opening schedule; access is set by trail. The Gran Cono crater trail and Strada Matrone are open from 9 am to 3 pm in January, February, November, and December, from 9 am to 4 pm in March and October, from 9 am to 5 pm in April, May, June, and September, and from 9 am to 6 pm in July and August. Crater visits must finish within one hour after the last permitted entry, and access closes automatically on days with regional orange-level or higher weather alerts. The Riserva Tirone trail is open Saturday and Sunday from 9 am to 4 pm, with last entry at 3 pm; some other trails may be partly or fully unavailable during maintenance.
