Starwood Hotels and Resorts has opened The Westin Snowmass Resort in Colorado, US.

Formerly known as the Silvertree Hotel & Conference Centre, the redeveloped resort is a joint partnership between Starwood Capital Group and Wasserman Real Estate.

Located in the centre of Snowmass Village, the hotel features 254 rooms including 18 suites.

The resort will house a spa offering a range of body treatments including detoxes and scrubs as well as facials and full-body massages.

Signature treatments include Altitude Adjustment, which uses oxygenated vapours to acclimate the body and increase its oxygen levels.

Duet Massages are also on offer using a variety of techniques including aromatherapy, a warm paraffin foot wrap and a scalp massage.

In-room treatments are also available to guests on request.

Dining options include The Snowmass Kitchen, an all-day restaurant with ski-in/ski-out access.

The resort also features a Westin Workout fitness centre as well as two hot tubs, a swimming pool and a 20,000sq ft (1,858sq m) conference centre.

Brian Povinelli, global brand leader for Westin Hotels & Resorts, said: "Guests can enjoy either winter skiing or summer recreation at a property that exemplifies the Westin brand's emphasis on wellbeing.

"As the newest addition to the Westin brand's already extensive collection of ski resorts, The Westin Snowmass gives travellers the opportunity to experience the Westin difference in the prestigious Snowmass area."
