Hi Brent—Sorry, the trail is still closed. It typically opens in mid June. You can keep checking the status here to see if might open early.:

The cable car is running and I think it would still be worth going up there to walk around. Just show them your Pass at the cable car station and they will give you a discount on the ticket price for the ride. You also have the option of the Grindelwald cable car to or from Mannlichen. So, you could take the cable car up from Wengen and then down to Grindelwald. Just be sure to tell the ticket counter your plan so they can issue you the correct discounted ticket.
I just checked the live camera for someone the other day and there is still some snow up there:

But still fabulous views!!
Glad to hear you’re enjoying your time.
