Cruises & Boat Tours

If you're an active bunch, there's nothing quite like getting out on the water in this wonderful temperate city. The Pacific Ocean is full of marvels, big and small, so why not scope them out on an afternoon Whale Watch? See the great gray whales alongside tiny seabirds and go home with a collection of phenomenal photographs. (Please note this tour is only available in the winter.)
Looking for something more along the lines of a relaxing sightseeing cruise? Then check out the San Diego Hour Harbor Cruise for a combination of informative narration and peaceful sailing. You have two options for the Harbor Tour: North Bay (which highlights Harbor Island, the Maritime Museum, and the Point Loma Lighthouse, a favorite lounging spot for many sea lions) or South Bay (focusing on the USS Midway Aircraft Carrier, Seaport Village, and Coronado Island).
San Diego Animal Attractions

Do you simply adore sharks? Then San Diego is the perfect destination for you! There are attractions to suit animal lovers of all stripes, from the amazing San Diego Zoo to their sister park, the San Diego Safari Park (maybe best known for its magnificent big cats).
If you prefer sea creatures to land mammals, another great option is SeaWorld San Diego. This amazing aquatic attraction combines the best parts of a theme park and an animal park all into one delightful package.
San Diego Museums

It's nearly impossible to narrow down the list of San Diego Museums to a few top choices, so we'll just have to settle for naming some of our favorites. The USS Midway Museum is a definite must-see; as one of the most popular attractions in all of San Diego, it's got a lot to offer fans of military history and naval culture.
Art lovers will also find much to enjoy about San Diego's museum scene, which features everything from fine arts museums (like the San Diego Museum of Art) to those which focus on photography and contemporary offerings (like the Museum of Contemporary Art). Of course, with nearly 20 museums and attractions to choose from in the Balboa Park area alone, you'll never run out of things to explore.
Amusement Parks

Feel like a kid again with a visit to Belmont Park, a delightfully retro amusement park featuring all your classic favorites like a giant roller coaster, arcade games, and cotton candy. Of course, there are plenty of modern rides, too, like the refreshing Beach Blaster or the fun Krazy Kars. Spend an afternoon enjoying rides, slides, and strolls along their palm-lined boardwalk and we know you'll have a wonderful time.
Sightseeing Tours

Searching for a way to explore the city that isn't just the same old bus tour? Check out the revolutionary San Diego GoCar Tours - the world's first GPS-guided storytelling car. Let it do the talking and navigating while you worry about nothing but enjoying the ride. It's an ideal way for adults to explore the city because it lets you go at your own pace, and stop and start the tour any time or place you want. Simply hop back in and the narration resumes.
Or, if you prefer something a little more charming and traditional, try a trolley tour of the city. This hop-on hop-off option gives you the flexibility to explore at your own pace and guided by your own interests.
Speed Boat Rides

Do you love the water, but want something more exciting than a leisurely cruise? San Diego has several options for you to choose from. Our favorite is San Diego Speedboat Adventure - an attraction that gives you the wheel of your very own exhilarating speed boat. Opt to cruise along at a leisurely pace, or rev up your engines to high speeds. It's a fun activity for adults who love thrills and being chill alike.
San Diego Sports

Head down to PETCO Park for a Padres game any time in season, or if they're out of town, take a tour of PETCO Park. This gorgeous downtown stadium is one of Major League Baseball's finest, and it's more than worth your time to at least stop by.
If you're a real sports buff, then you have more options depending on the time of year. Torrey Pines has a well-regarded golf course, and there are several college options.
Being Outdoorsy

Active couples and groups of friends will love the chance to get out and explore the beautiful weather and scenery of the San Diego area. Bike rides are a perfect boardwalk activity for you and your friends, allowing you the freedom to the roam the beaches while getting a little exercise.
Or, if you prefer to enjoy the beautiful waters of the coves and harbors in the region, try your hand at a tandem kayak?! There's even stand-up paddle boarding for the even more adventurous.
Coronado Island

This lovely island community is a must-see part of San Diego that visitors often overlook. It's part beachy delights, part historic heritage, and all wonderful. Explore the historic Hotel Del Coronado - today the home of many weddings and high-end parties -- bike the beaches, and visit museums. It's just a quick ferry ride from downtown San Diego!
You could also spend a little time in the Coronado Museum of History and Art, which features informative and interesting exhibits about this charming island.
Japanese Friendship Garden

After indulging in all this exciting fun, you may want to unwind a little and reconnect with the slower side of things. While you may not be able to squeeze in a yoga class while traveling, you can pay a visit to the lovely Japanese Friendship Garden in Balboa Park. (For more things to do in Balboa Park, see below.)
This serene garden is a haven from the hustle and bustle of the outside world, featuring a koi pond, a sand and stone garden, and many other beautiful plants within a cultivated gardenscape.
The Gaslamp Quarter

There are so many wonderful neighborhoods in San Diego that it can be hard to pinpoint the must-visits, but the historic Gaslamp Quarter is definitely on that list. Combining Victorian architecture and modern buildings into one beautiful, striking neighborhood, the Gaslamp Quarter is home to both historic attractions like the Davis-Horton House and modern nightlife / dining. Head here for a wide variety of options that span the gamut from dance clubs to fine dining establishments.
Balboa Park

There's nothing in the world quite like the magnificent Balboa Park. It's the country's largest urban cultural park, and is filled to the brim with top museums, gardens, concert venues, and so much more. Explore this beautiful expanse to relax and unwind with a picnic or leisurely walk, or, opt to explore with a visit to a couple of their many world-renowned institutions. Be sure to have your camera at the ready -- between the lush gardens and historic architecture, you'll be wanting to snap a photo every few feet!
