§ 75.001.Definitions

Four definitions, and the recreation list is what determines the statute's reach.

"Recreation" means an activity such as hunting, fishing, swimming, boating, camping, picnicking, hiking, pleasure driving (including off-road motorcycling and off-highway vehicles), nature study including bird-watching, cave exploration, waterskiing and other water sports, bicycling and mountain biking, disc golf, on-leash and off-leash walking of dogs, radio control flying, and rock climbing — or any other activity associated with enjoying nature or the outdoors.

The catch-all is doing the real work, and it is limited by its own terms to activities associated with enjoying nature or the outdoors. That is what confines the statute: an indoor activity, or an organised sport unconnected with the outdoors, is not recreation under this definition.

The enumerated list has grown steadily by amendment — disc golf, dog walking, radio control flying, and rock climbing are recent additions — which suggests the catch-all has been read narrowly enough that new activities need naming.

The liability section adds four more for governmental premises only: hockey, skating, soap box derby, and paintball.

"Agricultural land" means Texas land suitable for producing plants or fruits for consumption, fibre, floriculture, viticulture, horticulture, or seed; for forestry and growing trees for lumber; or for domestic or native farm or ranch animals kept for use or profit. The definition turns on suitability, not on current use.

"Premises" is broad: land, roads, water, watercourse, private ways, and buildings, structures, machinery, and equipment attached to or located on them.
