Sun, Heat, and Rain

  • Expect high temperatures, intense sunlight, and high humidity April through November. You will be spending most of your time outside, walking from one part of the mission to another.
  • Apply sunscreen, and wear loose-fitting, light-colored clothing and a hat or carry an umbrella.
  • Drink plenty of water.
  • On rainy days, be prepared for high water and some flooding at low water crossings. Never drive through moving water. Turn around, don't drown.
  • Lightning can accompany storms. If you hear thunder, take shelter.

Personal Safety

Always be aware of your surroundings.

1. Do not leave valuables (purses, computers, GPS, etc.) in your car. Vehicle break-ins do occur at the missions. You can avoid becoming a victim by keeping your valuables with you, and out of plain sight in your vehicle.

2. There are uneven walkways throughout the park, and low clearance entrances within the mission compounds. Watch your step and your head as you visit and explore each mission.

3. Please do not climb, walk, or sit on the historic walls (including the well that has steps up it!). Not only could you fall, but continued additional weight causes the mortar to deteriorate faster, leading to possible wall collapses.

4. Please don't climb the trees, it isn't worth that photograph.

5. Beware of the wildlife! Do not approach or feed any animal you encounter. Keep an ear and an eye out for bee hives/swarms (painful sting!) and fire ants (painful bite!). Please inform a Park Ranger of all sightings. There is also poison ivy (painful itch!) in wooded areas –Leaves of three, let it be!

6. Keep an eye out for bike riders.

7. Report all loose dogs to a Park Ranger; do not approach. The park is in an urban area, where stray animals are common.


Bike Safety

Stay safe while biking!

  1. Know where you are headed. Take a look at this Mission Reach Riverwalk Map. The Mission Reach Trail is a very popular biking route at the park.
  2. Wear a helmet while biking.
  3. Many bike lanes in the city share the road with vehicles, so take care when riding on city streets.
  4. All bikes should be walked while in mission compounds.
  5. Please bring a lock and dock in the bike racks provided at each mission.
  6. Leaning a bike against a historical building or structure can damage it.
  7. Do not ride or walk your bike across the Espada Aqueduct. It is very dangerous. Doing so threatens your own safety and also damages the historic structure.

Safety & Firearms

As of February 22, 2010, federal law allows people who can legally possess firearms under applicable federal, state, and local laws, to legally possess firearms in national parks. However, Federal law prohibits firearms in government buildings, including park headquarters, the Visitor Center at Mission San José, and the visitor contact stations at Missions Concepcion, San Juan, and Espada. Public entrance doors are clearly marked with a sign indicating that firearms are prohibited.

The mission churches are under the jurisdiction of the Archdiocese of San Antonio, which also prohibits firearms in its buildings.
