Just at the end of the zoo, one can find the HMI Darjeeling and there is no entry fee for this. You will find a statue of Tenzing Norge and a Museum. This place is mainly for aspiring Students interested in Mountaineering and we found a group of young boys and girls just completed a training and waiting for their certificate.
Tourists can try four types of adventure games for total Rs 100/- which we did and it was great. There is a eating place inside to have food which is quite good. We had Darjeeling tea with French fries which was fantastic considering the chill outside.
Altogether, you will love this.
