Is metal detecting legal in Texas? Metal detecting is not allowed in Texas state parks, and Texas has very little public land. That makes landowner permission the main way to detect legally in Texas. Gulf beaches are a common exception, but Padre Island National Seashore, a National Park Service unit, is off-limits.

Texas state parks are managed by Texas Parks and Wildlife Department (https://tpwd.texas.gov/state-parks/); check its rules before detecting in any state park.
