CordeValle sits at One CordeValle Club Dr. in San Martin, California, in the Santa Cruz Mountains. The fitness centre is next to The Spa at CordeValle and is set up for both cardio and strength work: Technogym treadmills, ellipticals and weight machines, a Peloton bike and a Peloton rowing machine. Personal training sessions run 60 minutes and cost $200, one-to-one, built around whatever you're working on — body composition, general health, or your golf swing or tennis game.

Yoga is bookable as a private 60-minute session for $200, or as a group session for $200 plus $20 per additional attendee. Guided hikes last 60 minutes for $200, with $20 per additional person, and take up to six people along trails through the tree-dotted foothills, countryside and vineyard.

The heated outdoor pool is open year round and looks over the golf course, with 180-degree views of the surrounding hills. Poolside service brings cocktails, salads, sandwiches and housemade pizza. Men's and women's locker rooms have showers, steam rooms and saunas, so you can steam after a session or before one.

What separates this from a dedicated fitness retreat is that nothing is scheduled for you. There's no fixed timetable and no group programme to join — you decide each day whether to train, hike, do yoga or sit by the pool, and pay per session for the coached activities. That suits people who want a resort stay with real training facilities rather than a structured camp.

The setting is quiet and green: hillsides, countryside trails and the vineyard are all on the property, and the resort is roughly 30 miles from San Jose in the south Bay Area.
