Try to find the spot where the photographer was standing.
The building at left is still the Lansdowne Arms Hotel, see Streetview and the historical OS 25" map at GeoHive.
Interesting that it is labelled Main Street. This was originally William Street, and is so named on the 25" map, surveyed sometime around 1900. However, it may have been called Main Street locally before the name was officially changed.
"Cork Bantry Glengarriff Killarney Prince of Wales' Route" on the side of the charabanc. Does that imply pre 1901 ?

Here is a bit more about the "Prince of Wales' Route" and a useful map. The four-horse coaches (see the one behind in this photo) were an extension of the Cork Bandon and South Coast railway between Bantry and Killarney, primarily used for tourist traffic.
... And a 1896 book, published by the Irish Tourist Development Pub. Co. which should have full details - catalogue.nli.ie/Record/vtls000182211 . Betting Mr French / Lawrence was sponsored by the ITD to do a series of photos c. 1895 ?!
I see a CTC sign above the name of the Hotel, introduced from 1887 per the Cycling UK website.
Nice - Thanks https://www.flickr.com/photos/gnmcauley! I have updated the note to match....
RIC man in a tall helmet suggests before 1900, when they started wearing a peaked forage cap.
