    Tips for your Travels:
    • Pair the following tips with the sample itineraries from our recent family adventure to make the most of your Saguaro National Park visit:
    • Always check the weather!
      • Come during the summer for the biodiversity, but be wary of the heat!
    • Allow for extended time to complete more challenging “elevation” hikes in Saguaro.
    • Carry more water than you think you need!
    • If traveling in the summer, map your hikes so you finish early - before 9am! - and save trips to visitors centers for midday when the temperatures climb
    • Winter is an amazing time for backcountry camping
    • November through April are the busiest months and parking is limited so consider coming later in the day and plan sunset hikes
    • Leave your pets at home as encounters with wildlife can be deadly
    • Loop drives offer great views with pull-offs for picnicking and trails for quick hikes
    • The Arizona-Sonora Desert Museum is a short drive from the park and features historic collections, live plants, and desert animals such as the javelina in a zoo-like setting
