There and Back Again

I would say that the same impetus toward 'adventure', which was an innate part of his being, was what landed Bilbo ultimately in Rivendell.

He'd had the affinity toward Elves, and an interest in the outside world long before Gandalf approached him about the Quest of Erebor. Indeed, Bilbo's apparent difference from others of his race were what attracted Gandalf to him as a part of Thorin's company.

Having given the Ring and nearly all his possessions to Frodo, there was nothing holding him to the Shire. He also needed the safest place possible in which to live, since Sauron had become aware of him and his connection with the Ring. What better place for Bilbo than Rivendell?

Except Bilbo was blissfully unaware of any of that; Gandalf didn't tell him. In fact, Sauron had no idea that "Baggins" and "Shire" were of any significance at all until he interrogated Gollum, not long before Frodo set out.

Well, fear of Sauron wasn't Bilbo's motive for going to Rivendell, but it was a factor in his staying there permanently.
Bilbo told Frodo that he'd considered going back to the Shire to get the Ring but had been dissuaded by Gandalf and Elrond because Sauron was searching for him.

The only time-frame during which that would have been possible would have been within the preceding year, IF (we don't know this) Gandalf passed through Rivendell on his way from Mirkwood, where he interrogated Gollum, to the Shire, where he had the "Shadow of the Past" conversation with Frodo. From thence he went straight to Isengard, and didn't reach Rivendell until shortly before Frodo's arrival there.

I want to point out that Bilbo, though remarkably well-preserved, was quite an elderly hobbit after all. Had he been younger, and had young companions, he might have adventured some more with them. However, that wasn't the case; but even so, Bilbo picked one spot to settle down where there was most diversity of what to do and how to feel. He says himself that it's just great to do everything from eating to exploring nature in Rivendell.

Also, I'm getting rusty, so I'm not 100% sure, but did he not visit the Lonely Mountain for a time while Frodo had the Ring in the Shire? He didn't settle down completely for quite a while.

He did get to Dale. I would imagine he saw the Lonely Mountain again, but doesn't seem like he visited:

'I got here without much adventure,' he said, 'and after a rest I went on with the dwarves to Dale: my last journey. I shan't travel again. Old Balin has gone away. Then I came back here, and here I have been.'...~Many Meetings

As for what Bilbo knew about the Ring and any danger he was in once settled in Rivendell:

'I hear all kinds of news, from over the Mountains, and out of the South, but hardly anything from the Shire. I heard about the Ring, of course. Gandalf has been here often. Not that he has told me a great deal, he has become closer than ever these last few years. The Dunadan has told me more. Fancy that a ring of mine causing such a disturbance! It is a pity that Gandalf did not find out more sooner. I could have brought the thing here myself long ago without so much trouble. I have thought several times of going back to Hobbiton for it; but I am getting old, and they would not let me: Gandalf and Elrond, I mean. They seem to think that the Enemy was looking high and low for me, and would make mincemeat of me, if he caught me tottering about in the Wild.'~ibid

It seems, perhaps, dormitat bonum Homerus. Gandalf didn't know anything in particular about the Ring until he found the Isildur scroll at Minas Tirith in 3017, and then questioned Gollum in Mirkwood. Aragorn would have learned what Gandalf knew (or was willing to tell him) in the same time-frame; presumably he went straight from Thranduil's halls to Elrond's. In other words, that old ring of Bilbo's couldn't have caused much of a "disturbance" until roughly a year or so before the Council
