when avast block a website, it is because it is dangerous / infected, now why would you access a site like that?

and what is the site address?

Submit it as a possible false positive. If it truly is, you'll have access.
Have you checked the page a virustotal

There isn't a way that doesn't involve some risk - first you have to know the site is clean, site hacking is one of the most common infection routes. What is clean yesterday could be hacked and a malware delivery site tomorrow.

First you should report what site it is - when giving the url change the http to hXXp to break links to suspects sites and someone can investigate.

If it gets a clean bill of health it can be reported as an FP - that point you could add the url to the Web Shield > Customisations > Exclusions.

VirusTotal isn't particularly good at checking sites for malware as it is essentially only looking at blacklist databases and not doing a malware scan.

As DavdR says approaching such a site is always risky. It could even break out of a sandbox or be risky to open with malzilla browser.
A way  to go there is via the cut and paste method with a decent script blocker and third party requests extension enabled (NoScript and RequestPolicy in Firefox)  via a webproxy. But again there still might be a risk whenever you haven't fully updated and patched OS and third party software (Java etc.).  Check the code here: http://linkeddata.informatik.hu-berlin.de/uridbg/index.php?url=
There is a lot of difference between visiting a site that is a known PHISH and visiting a site that will try to infect you with a file infector like Virut for instance, that one visit can mean saying goodbye to the majority of your computer files. 
As we do not know the site in question (noted with hxtp or wXw) we cannot even make a far guess as what you will be confronted with there.
Know that questionable sites like pr0n sites are more likely to attract malcode (who's gonna complain later).
