Major city · United States
San MarcosSan Marcos, California
Give San Marcos one night as a cheap North County base on the Sprinter line, or skip it and sleep in Carlsbad or Oceanside.
San Marcos sits on Highway 78 between Oceanside and Escondido, about 35 miles north of downtown San Diego. It is a suburban city with a university, a light-rail line and a restaurant strip, not a sightseeing town. Most travellers use it for a cheaper bed in North County and day-trip out by Sprinter or car.

- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Getting around
The Sprinter light rail (North County Transit District) links Oceanside and Escondido with two San Marcos stops, Civic Center and Palomar College. Breeze buses cover local streets. A car is far more practical for Restaurant Row, the lake and day trips; dial 511 for regional transit and traffic info.
