His entrance exists, but only for employees/functionarios. It used to be the normal entrance for everyone. This was changed. I went there a week ago and was told I cannot enter there anymore, but have to go to gate 5. The entrance to the trail is now at gate 5 ( https://maps.app.goo.gl/bEBGEvejcygNN14C6 ). To get to gate 5 you can enter the park at gate 1/2 ( https://maps.app.goo.gl/Gi7Kgpc3MuuBieJF7 ).
