Hi Larry, I have nothing much to add to Mike’s comments.
I agree it’s far better to park outside, the car park is very rough and can damage your car easily.
It’s at least 30 mins strolling time as I remember those days of having five year olds in tow.
Whilst the Bóquer Valley is very pleasant, there are many other places to see Balearic Warbler without the walk. I’m not so familiar with the north so if anyone can help Larry with an alternative site, that would be great.
Home now after a fabulous three day break birding in the north in the company of some great people.
Mike
