Novice angler

I am brand new to fishing, I needed a new hobby to do while I'm traveling for work, golf was getting to expensive lol. Any ways I'm in homestead right now for the next week or so and I saw this browsing google. I tried going to the Aerojet but couldn't figure out how to get on the north side where you could walk and fish the bank. The only exit I saw that might lead there said official use only. I tried fishing by the boat ramo but only made it about 10 min before getting attacked about horse flies. I'd love to try to get out there again before I leave if anyone has any instruction on how to get to the north side. Thanks.
