We had a similar itinerary this past late summer. We did Kylemore Abbey (wonderful and worth 4+ hours), the Sky Road (1-2 hours with stops) and several of the roads north of the Sky Road (around the Cleggan area) all in one unhurried day. We went after tourist season so there was very minimal traffic and no traffic delays. If you're going in Summer, allow some extra time, particularly for the Sky Road because everyone has heard about that drive. If traffic does seem to create a problem, head for any of the other local roads. The scenery is comparable. We took another day for the roads south of Clifden (Roundstone, the nature trail at the Alcock and Brown landing site, the local beaches, etc). Again, unhurried, all tiny lane driving, and we had plenty of time since days are long. We took a third day for hiking in Connemara National Park. Lovely vistas and the hikes meet a variety of enthusiasm levels. I don't know if you've picked your accommodation yet. We thoroughly enjoyed our stay at Abbeyglen Castle. I know, it's not really a castle (but few of them are). We splurged on a beautiful suite, and thoroughly enjoyed the warm fires, good food, castle-like ambience and great hospitality. My one caution would be to splurge at least a bit and avoid the cheapest rooms. Those tend to be small and placed near the pubilc areas.

The road is definitely narrow, but I think as long as you look ahead, and be prepared to pull over to make room for another car when necessary, you should be absolutely fine

The time tables for 2017 put sunset around 8:14pm on September 1 and 7:08pm by the end of the month.

Hi to you too... I am not a cyclist but the road is good but narrow so care needed with cars as always. Were are you coming from please? From Galway, take the Clifden road to reach the heart of Connemara, then see what you seek to visit. It is all utterly lovely. A favourite route is taking a right soon after going through Recess on the Clifden road from Galway, signed Letterfrack and Kylemore Abbey, . Across miles of moors and past a lake.Inagh. Quiet road and I think good cycling with little traffic. When you come to the main road then, left will take you to Kylemore, then Letterfrack, to Clifden, RIGHT to Killary Fjord I would go right! Then in Leenane, take the narrow right to Maam and Maam Cross for glorious scenery. Form there Cong maybe! So many lovely places. If you settle for Clifden, try the Old Bog road to Roundstone.. Enjoy!

I would get a B&B or Hotel in Clifden if you are going car-less as the public transit is hit or miss and the distance don't look bad on maps but roads are small, curvy and in season crowded. And I second the comment above the Sky road is beautiful but probably not safe for walking. A nice walk in the area is from Clifden town to the beach it is modestly challenging about 2-3 hours roundtrip. If you can get ahold of this book it may help "Walking in Connemara: Shorter Walks to Explore the Hidden Connemara’, Connemara Tourism 1996 I saw it when staying in area. Sorry do not remember any of the walks but our hosts used it to describe walks to guests. The B&B i stayed in the area has closed so can't recommend specific accomodation. .

Which monument? The Sky road is a long road so I'd need more details to help you.
