All the way from 60-70 and it took me just like 3 days

And shouldRuneScape 2107 gold you have at least level 60 Dungeoneering you can access Taverley source dungeon; Red dragons - Not really recommended because Red dragons can only be found in two areas if I'm not mistaken: Red dragon island in the Wilderness and Brimhaven dungeon and both are from a lender; Black dragons - Taverley is crowded everywhere I would not even bother so Zanaris is the best alternative imo; Metal dragons - Not much to mention here, all Metal dragons are at the Brimhaven dungeon (Mithril dragons being the only exception) and are not too hard to kill and have pretty decent drops; Frost dragons - 85 Dungeoneering demanded so it is not really an option for you right now unless you feel like coaching Dungeoneering. It is also possible to try to make money with Slayer but unless you get Dragon jobs all of the time I'm pretty sure you'll make more money just killing Dragons.

What Silv said are all pretty great hints. When I was your level I did . All the way from 60-70 and it took me just like 3 days. It had been dull as you don't really gain anything but experience there however. It's kind of weird since I do not recall what I've been doing 70-90. I know I've Chinned a few tasks, umm and done things like Ranging directors, the Circus. And of course Cannon.

If you don't have a issue with wasting some cash you could Cannon Dagannoths while you Range them as well. Or you could Chin, however I don't suggest Chinning til at 80+. Going to Yaks can be great exp/hr. Around 40k in the best currently probably. But that could be pushing it a little. Since there are lots of robots.

I have not attempted Fire Giants though. I see a good deal of folks doing it whenever I had a task of these though. So it has to be okay. Aviansies can be a fantastic money maker and okay exp. But I'm also afraid like Yaks, they have started to have a lot of robots. Hope I sort of helped. Range is probably one of my poorer CB Skills oncheap RuneScape gold for what to train on.
