As one of those involved in opening Giggel Rav, I would suggest that it is hardly worth a visit (unless you are a collector of obscure trips),
It constitutes merely a very low and wet section of immature stream passage which is the continuation of the upstream section of Brackenbottom Pot on its way to Gavel Rigg where the stream sinks.
Brackenbottom Pot on the other hand is considered well worth a trip...
