Bring a water bottle, hat, and sunscreen There's no shade in Pompeii; you'll be in the sun for hours. Make sure to bring a water bottle (there are places you can fill it up again). Wear a good sun hat, or bring an umbrella to beat the sun. And take the time to lather up with sunscreen a few times during the day.

Yes, you are absolutely encouraged to bring your own water bottles into the Pompeii archaeological site. In 2026, the site remains vast and largely uncovered, meaning temperatures can soar during the summer months. There are several ancient Roman public fountains (nasoni) located throughout the excavations that still provide clean, drinkable water today, allowing you to refill your bottle for free. However, be mindful that large glass bottles or massive backpacks (exceeding 30x30x15cm) are generally restricted at the entrance for security and preservation reasons. Bringing a reusable, lightweight plastic or metal bottle is the most practical choice to stay hydrated while exploring the miles of dusty, uneven stone streets without having to rely on the limited and often expensive concession stands near the forum.
