San Diego travel tips

1) Head to Pacific Beach for a relaxing getaway in San Diego

Pacific Beach is located next to Mission Beach in San Diego. Students have long preferred Mission Beach, so Pacific Beach is chosen by more mature vacationers who value privacy and comfort. The beach is very long. It stretches past the Crystal Pier and turns into North Pacific Beach.

2) Mind that San Diego legalized marijuana in 2018

Smoking marijuana in San Diego is not prohibited. The sale of cannabis is allowed only to persons over the age of 21. You can only buy marijuana in specially licensed stores that can be found in downtown San Diego.

3) Do you believe in ghosts? Take a peek inside a haunted house in San Diego

There are many legends around the Whaley House, where, according to rumours, ghosts live – a red-haired girl who was the daughter of the first owners and a man killed on the stairs right in the house. You can pop into the mansion for $8 and check the house yourself.
