If you’re in a hurry, you can make the 990 kilometers from Guerrero Negro  to Cabo San Lucas  in one long day of driving, with a stop for lunch in Loreto . But if your goal is to experience a little more of the outdoors (and to have a safer drive), you’ll want to take more time.
The side trip out to the Vizcaíno Peninsula  takes several hours, depending on road conditions. Once there, you might spend a couple of days, up to a week, exploring the coastal towns.
Allow 3–4 days for a whale-watching adventure in Laguna Ojo de Liebre  or Laguna San Ignacio , since it can take several attempts to catch the right conditions and to see the whales up close. You can easily spend 2–3 days in and around San Ignacio ; add at least two more for a trip into the sierra .
Mulegé  and Bahía Concepción  offer enough activities to occupy visitors for a couple of weeks—or an entire season—including hikes to nearby prehistoric cave paintings, snorkeling, scuba diving, fishing, clamming, birding, and kayaking.
