this place is BALLSOME, u've got to have some tough, strong balls to get urself on there. though its not that hard to push on a short distance about 4KM uphill(gradual increase of elevation) u gonna need a bit of explosive energy to keep up. 
i set my gear on 1-5 for easy and relaxing tour. 
once u're in your destination, you have to pay 20 pesos for entrance fee and extra 10 pesos if u plan to park ur wheels. Me i just carry my bike on and have it with me up on the Lava Wall, and since its kinda hard to carry it up about 10meters high, i just park it on the path.. cause nobody is in there except me.. so kinda safe to left ur mtb on the path below.. 
the helipad area, is a great place to view the landscape of city and its whole coastal areas. beyond you will see other town like sto. domingo and Bagacay. and lastly facing north the a great wonderful view of Mayon.
