You do have to pay to see The Lone Cypress in person by entering the scenic "17 mile drive", but don't worry it is just $10 a car! This 17 mile scenic route includes some of the most beautiful coastline in California and runs between the Pebble Beach Golf Links and Cypress Point Golf Course through the gated community of Pebble Beach. Also along this scenic route is Bird Rock, Spanish Bay, Spy Glass Hill, Point Joe and the 5300 acre Del Monte Forest.
This tree is so famous it has been featured in The LA Times - Postcards from the west series- https://www.latimes.com/travel/la-tr-postcards-lone-cypress-20130519-dto-htmlstory.html
