I decided not to post picture with all the entrances, But I'll post name of the places instead.
Well to my count there are
6 entrances to Technion !
2 - Main gates, 1 - at Mizrah Hadash, 1 - Canada Gate, 1 - hole in the fence in Canada dorms, 1 - entrance through the forest above Avironautics : 6 entrances
Well to be honest.. there another possible entrance for those who in fond of rock climbing. Somewhere between Science Park and Canada Dorms.
