When my daughter and I arrived in San Diego for a three-day mom-daughter getaway last spring, our schedule was packed full of places to go and things to see. After all, we only had three days!

On our first day, after a fun afternoon at a beachside amusement park, we began to walk back to our resort when we saw it: a baby sea lion sitting on the beach, alone and vulnerable. We stood just feet away, watching him rest his head on the sand, blink his eyes and occasionally waddle from side to side. My daughter crouched down with the camera, trying to get as close as she could without scaring him, with a look of pure joy and wonder on her face.

Locals told us it was a fairly common site on San Diego beaches, and that eventually the babies find their way back to the ocean. For my Colorado girl, though, this unique opportunity to view sea life in nature made her entire trip.

It reminded me that sometimes it’s the little things discovered during unplanned moments—a baby sea lion, ocean waves, a clamshell on the sand—that children will remember the most.

San Diego offers families a variety of experiences, from those simple nature activities to kid-pleasing museums and amusement parks.

It can feel daunting to budget for a family getaway, but October is a great month to visit San Diego, especially if you’re looking to save money. Kids can explore much of this west coast city for free October 1-31. In addition to miles of beaches offering hours of free sandcastle building, many of the hottest attractions have cut their admission prices for kids. Quick and affordable nonstop flight options make San Diego more feasible than other beach destinations for Colorado families and the fall is still a warm, but not too hot, time of year to visit. With costs reduced, you’ll feel less pressure to fill every last moment, making time for more serendipitous little discoveries.

Schedule Unscheduled Time

For a more stress-free travel experience, experts recommend that you not make plans on the first day you arrive — especially plans that require advanced-purchase tickets — in case you experience travel delays. Instead, use your time on the first day to explore your hotel. Lodging near the beach is usually entertainment enough when there is sand to dig in and waves to play in (especially for Colorado kids), and it’s free. When my daughter and I visited San Diego, our resort’s landscaping alone (the Catamaran on Mission Bay), with native flowers and plants, streams with turtles and ducks and tropical birds in the lobby, provided great arrival-day experiences and relaxed time for us to go on a mini adventure. The Paradise Point Resort & Spa offers bayside firepits for evening s’mores after a busy day.
