What I wanted was to take grandchildren on a bike ride, but to find a route which did not have steep hills, or cross roads, or lumps in the path, only way is ride it.
I tried going for a bike ride in the Forest of Dean, cheap mountain bike, started at Bracelands caravan site, the old site has been turned to chalet site, new one is lower down, but the forest tracks from the site does a reasonable circuit around the camp, but rather steep first section to get to route to river, once first second done rest seems same gradient all the way down. But it would not be an easy return.
Other routes go towards the Symonds Yat which I did, but there did not seem to be a forest track down, so took to the road, which is where I learnt the problem with cable disc brakes, which would slow me, but not stop me, I had not until then realised how they simply run out of travel, so light braking they work great, but heavy braking they need to be kept in adjustment. Lucky I met nothing coming up.
At the bottom the old railway was a good route to Monmouth with a ferry that will take bikes at Symonds Yat base, and a foot bridge half way (Biblins rope bridge) which will also take bikes, opposite side of river to old train track was still passable with a bike, but not as easy, but what I relied on was being able to call my wife to pick me up from Monmouth and second time took car down to Monmouth and parked car on Hadnock Road out crossing river on rope bridge across ferry and return on railway track, but needs to have done the route first to know you can put bike on boat and the route is reasonable.
I tried the Wirral loop cycle route, and got lost, from Shotton the route follows the coast past a nice cafe and then pub, but then goes through the village of Burton Point, I found old railway but went wrong direction I think, did it a second time, up to Park Gate but there are road sections, so easy to get lost. Again first attempt rescued by wife, which is not the idea.
Shotton to Chester loop still has a small road section, you can join the canal to get right into Chester, but you need to get to New Crane Street and cross that major road to get into the small park and on to the river route back, and there is a gate to lift the bike over to get to Tower Road/Raymond Street junction, it may be possible to gain assess to Upper Cambrian Road, but not tried.
And this is the problem, you can get just one point on the route which stops you, I took my dad around Alyn Waters park near Wrexham him in a mobility scooter, half way around I had to dismantle it and rebuild it other side of kissing gate, there was no reason for it to be there, both sides free assess from the cafe at car park. Wepre Park route to Ewloe the same, all the way through the Park no problem for bikes, then just at point where you go onto Castle hill farm road, there is a kissing gate, I could just about get the bike around it on rear wheel.
