If you're flying into LA or Long Beach airports, it is recommended to rent a car during the trip to Artesia as the public transport available within the town itself may not be the best option to get around. Renting a car would allow you to explore the various nature spots with ease and independence. A day of renting a mid-size car can cost around $35 with gas prices ranging from $3.50 - $4 per gallon.
If you have less than 7 days, consider keeping day 2 as a free day to rejuvenate yourself or catch up with some rest. If you have more time, consider exploring more cities nearby like Pasadena or go on a road trip towards the Grand Canyon. Lastly, remember to carry sunscreen and enough water for the nature hikes.
Long Beach Airport(LGB), located at a distance of 8 miles from Artesia, is the closest airport. LAX (Los Angeles International Airport) is 22 miles away and may take up to 1.5 hours in traffic to arrive.
