Hello Robin,
It's so exciting to hear about how your adventure is developing!
Regarding your decision, if you're looking for a more nature related plan,
Wicklow is known as the Garden of Ireland. A perfect place for wonderful walks, but it might demand a few days to avoid getting burned out like you mentioned.
Glendalough, on the other hand, might be the best option for a more narrowed visit to check in Co. Wicklow! Surely a fantastic gem located right at the heart of
Wicklow Mountains National Park.; it would definitely be a visit to the past, with more than 5000 years of history in
Ireland's Ancient East!
Also, be sure to check

Kilkenny City!
I hope this help and look forward to hearing more about your journey!
