Mazatlán's residents don't bother with the tourist gridlock on Playa las Gaviotas; when they want a little beach time they head to Playa Olas Altas. Visit for yourself and you'll soon see why: This lovely pocket of golden sand and aquamarine waves is decidedly more tranquil. And the few cafés that corral the area aren't as overpriced. You will see the occasional beach vendor, but if you're not interested, just say a polite but firm, "No gracias." And be warned: Playa Olas Altas means "High Waves Beach" and its Pacific waters are sometimes better for surfing than leisurely swims.
