Having your own transportation is a must in and around Houston, especially if you plan to explore outside the 610 Loop. Remember to bring plenty of insect repellent, as you’re likely to encounter mosquitos year-round. During hunting season (November to January), backcountry camping is restricted within some state and national parks. Check ahead of time. Most Texas state parks require reservations for both daytime visits and overnight stays, so be sure to book in advance.
