The San Diego Natural History Museum is the best museum in Balboa Park. Fossils,
living collections, regional wildlife, and a film included in the ticket price —
four floors that a whole group can walk into without anyone quietly resenting the
choice.
Most of these sit along El Prado, close enough together that you can change your
mind on the walk between two of them. Two more are out past Pan American Plaza
and want a decision before you set off. The tickets swing hard: one of these is
permanently free, one runs $35, and one hands you a year of coming back.
The Explorer pass covers 16 participating museums and cultural institutions, and
the park holds more than that. Performing arts, special events, and many special
exhibitions sit outside it. Work out the two or three buildings you
will genuinely walk into before you buy anything, and check Resident Free
Days while you are at it.
Park once and walk everything. Start with whichever building closes first, and
give the end of the day to the one that stays open latest.
For the rest of the park — gardens, architecture, and everything that is not a
museum — there is the wider Balboa Park guide.
With small children in tow, start from things to do with
kids before you buy several
tickets.
