Beautiful hiking opportunities along the coast. Both Lexi and Eric strongly recommend it if you have the time.
Eric's favorite local restaurant. Great lunch spot If you're in the mood for mouth watering sandwiches paired with their signature house sauce (not a sponsor).
PGA Golf Course Open to the public. Neither Lexi or Eric have any golf experience, so this recommendation is purely hearsay.
One of the best spots for viewing the local marine life, but brace yourselves for their potent smell. Walking distance from plenty of shops/restaurants.
It's a bit of a drive, but you can fill a full day at the botanical gardens, museums, and San Diego Zoo.
