is there some place near San Jose airport to store extra luggage while exploring CR? Plan to backpack for awhile and head to Pacific coastline to start.
Unfortunately, they do not offer baggage lockers/storage at the airport. And there aren’t really any nearby offsite services like that either.
I think your best bit is to leave your bags at your San Jose hotel while you travel. If you’re not staying overnight in San Jose prior to traveling, you might ask a nearby hotel if they could keep your bags for a fee. There is a Courtyard Marriott right across the highway from the airport.
