Lawrence Palmer appeals the district court’s judgment in favor of the United States in an action under the Federal Tort Claims Act.
I
On June 23, 1988, Palmer visited the swimming pool at the Tripler Army Medical Center (TAMC) in Honolulu, Hawaii. Although not an employee, Palmer was permitted to enter the facility at no charge in order to accompany his grandchildren. The grandchildren were allowed to use the pool because their mother, Palmer’s stepdaughter, worked at the TAMC. Palmer, however, was told not to use the swimming pool.
Palmer removed his shirt and shoes and relaxed in a lounge chair as he watched his grandchildren swim. He went to the patio area to retrieve his sunglasses. Palmer slipped and fell while descending a flight of six stairs on his way back to the pool area.
Palmer brought suit under the Federal Tort Claims Act, 28 U.S.C. §§ 2401-02, 2671-80, alleging that the United States was liable for his injuries because its employees maintained the steps upon which the fall occurred. Following a bench trial, the district court ruled that the HRUS immunized the United States from liability for Palmer’s injuries.
II
The HRUS, Haw.Rev.Stat. §§ 520-1 to -8, provides that “an owner of land owes no duty of care to keep the premises safe for entry or use by others for recreational purposes, or to give any warning of a dangerous condition, use, structure, or activity on such premises to persons entering for such purposes.” Haw.Rev.Stat. § 520-3. The immunity afforded an owner by the HRUS, however, is not extended to injuries resulting from willful or malicious omissions, injuries to a person who pays a fee to enter the land, or to injuries of “house guests.” Id. § 520-5. 1 The statute’s purpose is “to encourage owners of land to make land and water areas available to the public for recreational purposes by limiting their liability toward persons entering thereon for such purposes.” Id. § 520-1.
We review the district court’s interpretation of a state statute
de novo. Salve Regina College v. Russell,
— U.S. -,
A
Palmer’s first argument is that the term “premises,” as used in the HRUS, does not apply to urban swimming pools. Because the courts of Hawaii have not spoken to this issue, we look first to the language of the statute.
Brock v. Writers Guild of Am., West, Inc.,
Palmer relies upon a number of cases from other jurisdictions holding that recreational use statutes do not apply to urban settings.
See, e.g., Gibson v. Keith,
We see nothing in the language of Hawaii’s statute that makes a distinction between urban and rural properties. If the legislature wished to deprive urban property holders of qualified immunity, it could have easily done so. It is not our role as a court to rewrite the plain language of a state statute.
See Mansion v. United States,
The United States has chosen to make the pool at TAMC available for recreational use free of charge. Thus, the HRUS is applicable to the pool under the plain, unambiguous language of the statute.

Palmer next argues that the United States should not be protected by the HRUS because Palmer was not engaged in “recreation” at the time of the accident. He argues that he was engaged in the non-recreational activity of supervising his grandchildren and was not permitted to use the swimming pool.
Even assuming that watching over one’s own grandchildren is not a recreational activity, Palmer’s services conferred no benefit upon the TAMC. See Mansion, at 1118 (rejecting argument under California statute that presence of retiree at military recreational facility conferred a benefit upon the facility by promoting good labor relations); Cedeno, 301 S.E.2d at 267 (purpose for which public is allowed on property is determinative). He was not there for the TAMC’s purposes, but rather to facilitate his grandchildren’s authorized use of *1137 the pool. Indeed, Palmer admits in his brief that he “had extended a service to his stepdaughter who would not have been able to have her children in the pool without Palmer’s supervision.” He was allowed on the property for his granddaughters’ recreational purposes, which is the type of permissive use the HRUS seeks to encourage.
Moreover, Palmer’s behavior was consistent with relaxation and recreation. He was lounging in the sun. We therefore conclude that he was engaged in a recreational activity for purposes of the HRUS. By affording immunity in this situation, the purpose of the HRUS to encourage landowners to make their recreational property available for use is served.

Finally, Palmer contends that even if the HRUS immunizes the United States from liability, the government nonetheless is liable for Palmer’s injuries because it voluntarily assumed a duty of reasonable care. He argues that by hiring lifeguards, washing down the steps, and generally maintaining the pool area, the United States voluntarily undertook a duty of reasonable care.
We disagree. Application of the HRUS precludes other theories of liability based upon mere negligence. Nothing in the language of the statute or its legislative history indicates that Hawaii intended the HRUS to apply only when the landowner fails to take any precautionary measures to ensure the safety of recreational users.
Palmer primarily relies on
Collard v. United States,
Collard
also relied on
Stephens. Stephens
held that the government voluntarily assumed a duty of reasonable care by enacting safety regulations for a federal reservoir and conducting inspections.
Stephens,
The Tenth Circuit’s opinion in
Klepper v. City of Milford,
The RUS itself is a statutory modification of the common law of torts and provides for no liability for simple negligence. Instead, it provides for liability only where conduct is willful or malicious or where consideration is given in return for use of the recreational facilities. If the Kansas legislature had wanted to provide for additional exceptions, such as liability for negligent inspections, it could have so stated. To rule otherwise would have the effect of defeating the purpose of the RUS.
Id. at 1450. Similarly, Hawaii has not provided for an exception to the HRUS when the landowner engages in voluntary efforts to improve the safety of its property. We *1138 refuse to create such an exception, particularly since the result might be to discourage efforts to make recreational facilities safer. See id.
Ill
The HRUS shields the United States from liability for ordinary negligence. The judgment of the district court for the United States is therefore
AFFIRMED.
