$28 for adults gets you two consecutive days of admission. Military with ID are free under their Field of Flags program.
28 for adults
Their website has all the prices and membership info.
You can find current admission prices here: https://www.osv.org/visit/; the 2nd-day admission no longer applies, but you can buy a season pass for unlimited daytime visits through the season.
Our admissions were on the Boston Go Pass. The pass is amazing. $149 for adult 5 day pass,$115 for children. There is so many attractions on this pass is it mind boggling. We saved hundreds of dollars on admission fees.
