Ice caves in the summer?

Visiting in late June and seeing unclear feedback on the posts here - sounds like maybe there were some worth going to in the past that have since collapsed. Also sounds like it might potentially be unsafe during melt season. We’ve also heard from friends who visited that there are easy ones to get to and more “adventurous” ones that require climbing / hiking that may be best in the summer. Any thoughts seriously appreciated as well as recommendations on any specific companies worth checking out. Thanks in advance!
