If you live in Castro Valley and need urgent care in Castro Valley or nearby, CityHealth San Leandro is your closest and most convenient option. We’re just about 10 minutes away, and we offer the full range of urgent care services — walk-in, same-day, no appointment required.
Castro Valley doesn’t have a dedicated urgent care clinic. When residents get sick or injured, they’re often left choosing between driving further for urgent care or heading to the emergency room at Eden Medical Center right in Castro Valley. This guide will help you understand your options and why CityHealth in San Leandro is the better choice for most situations.
Urgent Care Castro Valley: Your Options
Castro Valley is served by Alameda County but sits in a gap between the urgent care clinics of San Leandro and the clinics in Hayward. Here’s what residents are working with:
- Eden Medical Center ER (Castro Valley) — A full hospital emergency room on Castro Valley Blvd. Great for true emergencies. Not the right fit for non-emergency urgent care needs — long waits and high costs.
- CityHealth San Leandro — 10 minutes north on I-580. Full urgent care services, extended hours (Mon-Fri 8am-8pm, Sat-Sun 9am-5pm), walk-ins welcome, on-site lab and X-ray.
- Other options — There are urgent care clinics in Hayward (15–20 min south) but CityHealth’s hours, services, and proximity make it the strongest choice for Castro Valley residents.

Urgent Care vs. Eden Medical Center ER: Which Should You Choose?
Eden Medical Center is a full-service hospital with a 24-hour emergency room. It’s a great resource — but it’s designed for emergencies, not for the everyday urgent medical needs that most people have.
Here’s a simple breakdown:
Go to Eden Medical Center ER (or call 911) if you have:
- Chest pain or pressure — possible heart attack
- Stroke symptoms — face drooping, arm weakness, speech problems
- Severe difficulty breathing
- Uncontrolled bleeding
- Major trauma — serious accidents, deep wounds, head injuries
- Loss of consciousness
- Severe allergic reaction with throat swelling
- High fever in an infant under 3 months
Come to CityHealth San Leandro for:
- Sinus infections, strep throat, ear infections
- UTIs and bladder infections
- Flu, COVID-19, respiratory illness
- Sprains, strains, minor fractures
- Cuts that may need stitches
- Burns (minor to moderate)
- Rashes, allergic reactions (non-severe)
- Pink eye, eye irritation
- Nausea, vomiting, stomach pain (non-severe)
- Lab work and STI testing
- X-rays for injuries
- Drug screens, physicals, workers’ comp
The difference in cost is significant. An ER visit typically runs $1,000–$3,000+ for non-emergency issues. Urgent care at CityHealth is a fraction of that — and your copay is far lower when you’re insured.
