On climbing the hill a little further one can find a Jogimut and Pandava cave. There's no supporting literature or folklore that links the cave to the Pandavas. The cave itself is very suspect and there's no way it could hold the Pandavas (especially Bheema) during their Vanavasa. So yeah in my opinion you just have to treat it as a tourist spot - nothing less, nothing more.
Getting-there: Right in the heart of the city. The buses are a good medium of transport to get around in Mangalore.
My Rating: 5/10
