Texas
Trespassing Laws (Purple Paint)
Texas originated the use of a stripe of purple paint as a legal substitute for a posted No Trespassing sign. This allows for a quick and inexpensive method of posting large land areas. If you see purple paint on posts, poles, or trees, they are legally the equivalent of No Trespassing signage and should be treated as such. Many other states have since adopted this same law.
Playgrounds and Playground Equipment
Adults not accompanied by children and seen lurking around playgrounds raise suspicion and may attract unwanted attention from both concerned parents and law enforcement officers. Therefore, caches on playground equipment and caches in or close to playgrounds will not be published.
Event Stacking
Events, including CITOs, scheduled for the same day must be separated in time by 2 hours (time between the end of the first and the beginning of the second) OR in distance by 20 miles between the two locations. HOWEVER, special guidelines apply during MEGA and GIGA events as described below.
On the day of the MEGA or GIGA event, there can be one additional event (hosted by the event team that cannot overlap in time with the Mega. The distance restriction for other events is increased to 50 miles
On the day before and the day after the MEGA/GIGA side events are limited to two events per day, and not back-to-back.
CITO events cannot occur on the same day as a Mega-Event (within a reasonable distance).
Two or more days prior to and after the event, normal event stacking guidelines apply.
Texas State Parks and other recreational areas
Geocaches placed on Texas Parks & Wildlife lands, including state natural areas, are required by the Texas Parks & Wildlife Department to have a permit and adhere to a set of park guidelines. Verbal approval from a Ranger is NOT sufficient. There must be a permit on file.
In general, cache permits are approved, unless the cache is in a sensitive location. Exceptions are the following parks, where caches are often not approved, but this is up to the rangers on site:
Caprock Canyons
Brazos Bend
Monahans Sand Dunes State Park
A PARTIAL list of the guidelines follows. The full text of the guidelines plus a geocache permit form, can be downloaded in PDF format here: Texas State Park Cache Placement Permit
A cache permit must be completed by the person placing the cache and approved by the Park Superintendent or designee before a cache can be placed on a state park or historic site. The permit must include the exact cache location, including GPS coordinates; name of geocacher placing the cache, a valid address, telephone number, email address (if applicable), driver’s license number (if applicable), and the website address on which the cache will be posted. Permits shall be renewed annually.If a cache permit is not current, park staff may remove the cache as abandoned property.
The location of the cache must be pre-approved by the Park Superintendent or designee, whose main concern will be public safety and prevention of undesirable impacts to natural, historical, and cultural resources.
If it is determined that a cache has been the cause of adverse resource damage, causes a public safety concern, or is unauthorized, the cache may be removed by the Park Superintendent or designee at any time.
Cache containers must be non-breakable, have some form of latch or other closing mechanism to prohibit content exposure to wildlife, and must be approved by the Park Superintendent or designee.
Each cache container, excluding micro-caches, must have an identification label affixed to the outside identifying the name of the cache and date of creation.
Caches shall not be placed in a location that leads to the creation of spur trails or other resource impacts.
Caches may not be placed in dangerous, inappropriate, or protected areas and habitats, on cliffs, underground, or underwater.
Caches shall not be placed in a location that is visible to the casual site visitor or that will degrade scenic views.

NATIONAL CEMETERIES
The National Park Service Reference Manual 61, National Cemetery Operations prohibits "Engaging in recreational activities" in National Cemeteries
RAILROADS
A railroad's right-of-way generally extends well beyond just the railroad bed. The general rule is to keep geocaches at least 150 feet from any railroad tracks, including elevated tracks, unless the railroad right of way is delineated. If the cache is placed in a rails-to-trails area and you can demonstrate that the tracks have been removed, or the cache is clearly outside of a marked or bounded right-of-way, the cache may be considered for publication.
VIRTUAL POSTED COORDINATES
Generally, if the posted coordinates for a multi-cache, puzzle cache, or Wherigo cache are virtual coordinates, they must not be placed in any restricted area listed above without permission of the landowner or authority controlling the property. This helps avoid confrontations for new geocachers who may not understand what a virtual waypoint is.
