Border to Border: Essential road trip stops along I-5

I-5 then takes you into San Diego. You could literally spend days exploring San Diego since there are so many things to do here, but the one must-see attraction in the city is Balboa Park. San Diego's natural history museum, air and space museum, zoo, science center, and art museums can be found set among the gardens here...and that's just naming a few attractions you an check out. It's worth at least visiting their legendary zoo or the Automotive Museum!

And if you need a hotel in San Diego, look into the Manchester Grand Hyatt, the Hotel del Coronado, or The US Grant.

Surfing, fishing, camping and beach access for day-use visitors make South Carlsbad State Beach a great place to spend some time. If you can, stay to watch the sun set over the water: there's nothing quite like it.

Next pay a visit to Mission San Juan Capistrano. The history of Spanish missionaries coming to California is important, and also sobering; there are 2,000 inhabitants of this 18th-century mission buried in unmarked graves, mostly Native Americans. The ruins of the old stone building are also quite fascinating to see.

Since you're driving right by along I-5, why not stop at Disneyland in Anaheim? A trip here won't be cheap, but it is the "Happiest Place on Earth." Plan out the things you really, really want to see, do and eat and familiarize yourself with the park beforehand to make the most of a day here!

Skeletons in the Closet is one of the quirkiest and most morbid attractions in LA! What started out as a joke among staffers making fun of the morbid souvenirs sold at places dedicated to the part of LA's history when murder rates were at an all-time high spun off into a full-fledged shop selling toe-tag keychains, skull-shaped business card holders and other dark takes on kitsch. Just let the guys at the front desk know that you're there to do some shopping!

If you plan on spending the night here, there are loads of nice hotels in LA. Farmers Daughter Hotel, the W Los Angeles and the Georgian Hotel are among the many places to stay!

If Disney isn't really your scene, then you might be more into Six Flags Magic Mountain, also right off I-5! Here, it's all about the intense roller coasters. In fact, it has the most coasters of any theme park in the country. In addition, there are also thrill rides for those of all ages, and some water rides too.

There's tons of natural beauty along I-5. Between late winter and early spring, Antelope Valley California Poppy Reserve explodes with brightly-hued flowers, mostly poppies. Seven miles of trail make for awesome wildflower viewing, or for a good place to stretch your legs after long hours in the car.

If you're into James Dean, history, pop culture, or offbeat roadside attractions, the Last Place James Dean Stopped in Lost Hills fits the bill quite nicely. James Dean died at the young age of 24 in a car crash while driving in his famed "Little Bastard" Porsche Spyder not far from this gas station. There's a 50's themed diner and general store, all bedecked with the legendarily handsome actor's likeness.

New Idria Ghost Town, built around a former mercury mine, was only abandoned in the 1970's so there are still nearly 100 buildings left, although they've been vandalized quite a bit. It's not as rustic as some ghost towns, but it's a cool place to stop and take some gritty pictures.

Another nice place to stretch your legs is the O'Neill Forebay Wildlife Area in Gustline, CA. It's perfect for camping, or if you pick up some food, for a nice afternoon picnic. If you have time, you can also enjoy the swimming and boating here and at the other nearby reservoirs!

Or, another great place to picnic is Bogle Vineyards and Winery... and, as an added bonus, Bogle also gives you complimentary wine tastings in a serene vineyard setting. Their wines are known for being delicious and reasonably priced, so pick up a few bottles as a souvenir.

Whether you're a Johnny Cash fan or not (the singer famously played a show for the prisoners here in Folsom), you're sure to find the Folsom Prison Museum interesting. You can see inside an old cell, and look at handmade weapons crafted by the inmates at one of California's most notorious lockups.

Dive Bar in Sacramento is a kitschy spot featuring specialty drinks, beer, pub grub, and real, live mermaids! Okay, maybe they're not "real" mermaids, but the performers in full mermaid garb who put on shows in the massive tank make this place totally worth a visit.

Stay the night at the Citizen Hotel, the Sterling Hotel, the Inn off Capitol Park, or one of the other nice hotels in Sacramento.

If you keep driving up I-5, you'll reach Chico, home of the National Yo-Yo Museum! Located in a super-cool indie toy store, the Yo-Yo Museum boasts the world's largest yo-yo, 80 years of yo-yo artifacts, and hosts the National Yo-Yo Championship each year. It's a super cute way to kill an hour!

The town of Shasta, which was active during the mid-19th century, is mostly abandoned today. However, the old buildings have been preserved at Shasta State Historic Park. Step back in time at the jail, the store, the church, the museum, the post office, and the school.

The stunning Lake Shasta Caverns, which must be reached via a boat, are one of the coolest attractions in the area. As you traverse the system of caverns, you'll learn about their fascinating history and see all kinds of wild rock formations. It's a bit of a trek, with about 600 stairs total, but it's well worth the effort.
