The Vatican Grottoes are open to visitors every day from 9am to 6pm, and the entrance is completely free. To access this underground treasure, you&#8217;ll first need to enter St. Peter&#8217;s Basilica. Once inside, look for the staircase near the papal altar (it&#8217;s close to the statues of St. Helen and St. Andrew) and make your way down.<\/p>\n<p>Here&#8217;s a pro tip: explore the basilica first before heading to the grottoes, as exiting the grottoes will lead you outside the church. If you want to return to the basilica afterward, you&#8217;ll need to rejoin the entrance queue \u2013 and we all know how long that can get!<\/p>\n<p>For a deeper experience, <a href=\"https:\/\/www.headout.com\/st-peters-basilica-tickets\/st-peters-basilica-dome-guided-tour-e-10479\/\" target=\"_blank\" rel=\"noopener\"> guided tours<\/a> are available with online booking.

Having travelled to most of North India when I was a kid to backpacking across South India in my adulthood, I learnt that you often find your 'self' in the most unpredicted of places. And that is my inspiration to travel. To connect with nature, people and cultures. Books are my companion and I find my soul in trees. Music, yoga and literature is my passion. I often dream of attending a Peruvian wedding or living in a quaint Hungarian town for a while. When I am not writing, I think of the Himalayas or go running.","sameAs":["https:\/\/www.instagram.com\/just.rohit10\/","https:\/\/x.com\/https:\/\/x.com\/rohitjadhav786"],"url":"https:\/\/www.headout.com\/blog\/author\/rohit-jadhav\/"}]}},"_links":{"self":[{"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/posts\/199819"}],"collection":[{"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/users\/122"}],"replies":[{"embeddable":true,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/comments?post=199819"}],"version-history":[{"count":10,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/posts\/199819\/revisions"}],"predecessor-version":[{"id":200868,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/posts\/199819\/revisions\/200868"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/media\/200019"}],"wp:attachment":[{"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/media?parent=199819"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/categories?post=199819"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.headout.com\/blog\/wp-json\/wp\/v2\/tags?post=199819"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
