Nearest subway at Hillhead, Byres Road. 5 mins walk

There was the 2 buildings and the park. Can easily be done in under an hour if you rush but likely no longer than 2 hours if you take your time. Double check the openning time. Google indicated a 10AM openning and when I arrived there was a sign on the door that they didn't open the buildings until noon. Might have been a covid thing and could have changed by now.

You sure can. I see many people walking dogs in the gardens.

Yes, as the architectural experience of the hothouse will be the same, but less crowded....and is cosy warm in the worst of scottish weather!

The best way is via the underground station from Buchanan Street to Hillhead, and walk a short distance. There may well be a street map at the station.

as above answers paths all the way round

Yes

No entry fees to the gardens - it's free!

The clockwork orange (the SPT) is brilliant you should get off at hill head and walk up the hill. You will go past Waitrose on the left. With a Waitrose loyalty card you can get a free coffee to take into the garden. You can get one for each adult. On the right just down Cresswell street superdrug and oxfam books are on the corner you can get fabulous milkshakes at the Atrium cafe. Oxfam books is wonderful to buy a book to read in the botanical. It is roughly £9 to get a taxi from the middle of town to the gardens so if there are several of you this may be the cheaper option. There is a taxi rank outside the gardens for a return trip. We love the cafe right in the gardens it sells very fresh food. Hope this helps!

Admission to the Botanic Gardens and conservatories is free
