Best time to visit Anytime, but June through October is the high season. While the fishing is great, summer fog makes San Quintin feel more like San Francisco than Baja. San Quintin's prices are higher at some places than you would expect for a small town so far from the border, but there is a full range of price options for food and lodging. Culture shock Minimal. Credit cards are accepted at most of the larger motels and restaurants, but it doesn't hurt to carry some cash here.
Dollars are fine anywhere.
English is spoken at the hotels, but not universally spoken throughout town. Kid-friendly Not really. There isn't much for kids to do in San Quintin. While the beaches are wonderful, getting to many of them can be a chore. If you have kids along and are staying more than just overnight, try Celito Lindo Motel or the La Pinta on Playa Santa Maria.
