It's worth going on the cable cars if they're on.
Worth going up just for the views.
The views are pretty decent. Use the (free) toilet in visitor centre rather than the one opposite.
Cafés, trams and cable cars operate from the end of March. Bring a picnic but keep a tight hold of your rubbish.
Get there by cable cars the scenery is beautiful
Fantastic views from The Summit although Snowdonia is likely to be hazy. Some very good walks to be had from here. Descent to Halfway Station to view the amazing Bronze Age copper mines
Get up there with a couple of friends and leave your mark on the "Hill of Names"...
Stay on for sunset over Anglesey. Up there with the best.
You can take the Tram to the summit or if you're feeling slightly more energetic walk up. The views from the top are well worth the trip.
Don't bother eating at the Summit Complex, the Captain's Table or whatever it's called is just a canteen style cafe, but it charges the earth! £8.95 for fish and chips?
