There are tons of things to see and do in and around Utrecht during your stay. For a cultural experience, you’ll want to use your Utrecht car rental to check out the Centraal Museum, the Rietveld Schroder House, and the Castle de Haar. For some natural beauty, head to the Utrecht Botanical Gardens and Sonnenborgh Observatory. Utrecht also isn't very far from Amsterdam. If you're looking for a day trip into the Dutch capital, it's only about a 45-minute drive one-way.
