A word of caution on bouldering in Hampi. It goes without saying that bouldering is a risky sport. If you are a beginner try it only under proper guidance.
Like mentioned earlier, the boulders in Hampi are granite. They are not kind on softer skin. The boulder surfaces, especially the less exposed vertical faces, are rough and can be flakey. Monsoon season can make the surface slippery. Heat in the summer can really become unbearable for those of you who are not used it. See a more detailed account of the Hampi's climate .
It is not very rare to spot reptiles in the pits and shrubs around the boulder fields.
The langurs ruling the area can become your companions or enemies (if felt threatened) depend on how you treat them. There is no interspecies bouldering competition here. At the best borrow a couple of betas from them and leave them alone to their problems. That is going to be your effective strategy to deal with these master climbers.
Never try to tease or shoo them off. It's not going to work. They respond even to mild attention. Ganging up, hissing and grunting are typical signs of their agitation. Just ignore them and stop any provocation, they will simply disperse after some skeptical moments. You can go on with just another problem.
If still they are hanging around, see if someone is wearing a Tshirt with banana print on it!
While trekking off the trails, be on the lookout for the broken glass pieces (yep. beer bottles!) and those wicked thorny shrubs.
Do not venture alone into lonely places. Incidents of mugging is rare, but be prudent. Be careful with expensive things. Do not leave it unattended in the site.
To a question on his climbing movie Pilgrimage Chris Sharma responded saying Hampi is sacred to the Hindus since it is the birthplace of Hanuman, the monkey god. Also Hampi is a place for pilgrimage to the boulderers, since boulders are temples for them.
