Puertocitos is a hole, anyway. The ride from Tecate to Mike's Sky Ranch, via Laguna Hanson, is the best. There are several rides around Mike's Sky Ranch that are very challenging and very fun. It is all high country, so you may hit snow or rain in the early Spring or late Fall. San Filipe is a fun ride and a fun town to visit.
Spring Break is the best time to go there.
Lots of scenery, if you know what I mean. It is too hot in the Summer, though. Pack light and bring dinero. Do not count on being able to use your credit or ATM cards anywhere except in the large cities. You'll have to use cash for most purchases.
