Need a high alch spot

Hey everyone, I'm currently 65 Mage going for 82...Any advice where I should high alch? I can't get to barrows cuz I have no idea how, or what quests, etc.
I heard about the fally spot, and I heard about the duel arena spot, but can anyone help me out? I'm trying so hard to autoalch but the randoms are just murdering me...

 

Dude go to the top of duel arena where you can lean to watch fights.. alch there no randoms.

Edit: Pest control boat stay in it dont un board and alch also no randoms.

 

i dont really feel like getting banned because i was by myself on the boat autoing. i just want a spot where i can start auto alching, leave for 3 hours, come back, and im still alching. I HATE RANDOMS.

 

dont auto alch jagex will find out. Easy autoer they can find

 

Edgeville bank.

 

edit: didnt read lol , best bet is duel arena

 

in the fight pits

 

Edgeville bank, or duel arena go to like the middle so no1 spots you, and theres no randoms.. so..

 

Okay so why am I getting a shit ton of different answers?
I just want a spot where i can for sure high alch like 2k yews w/o having to deal with a random. I like to just set my auto-alcher, leave for like 2 hours or more, and come back with the shit still training. I just don't want to like leave, then have a random kill me, or have a rs pmod fuck me over.

Where exactly if I goto the duel arena, should I go?
Fight pits? Can someone explain that more in depth please? Oh and I've had many a random while alching in edgeville bank.

 

the dual arena is ur best bet i did it there never got a random

 

duel arena is the best
